Michael Frostad, MD - Palouse Pediatrics

Philosophy of Care:

The privilege of my job is to assist parents as they try to raise their children to be happy, healthy, and to make good decisions in life.  It is a journey that we partner in and my role is to provide education for the family regarding current evidence based practices, medical counseling and expert recommendations.  With this collaboration, we often share times of joy and pride, as well as sorrow and frustrations as the children mature. 

Every child is different and every family is different.  I get to help parents gain the confidence to be the parent they want to be, and encourage children to develop into their own personhood, while keeping general wellness as a primary goal.


Why a Pediatrician:

I wanted to be a physician so I could help people.  My father was a Pediatrician here at Palouse pediatrics for over 40 years.  Those who know my father know that I am a lot like him.  I look like him, I walk like him, I talk like him and we share many of the same mannerisms.  So, in medical school I initially wanted to focus on something a little different than what my father did.   I thought I was heading towards Emergency Medicine instead of pediatrics, but during my medical school rotations, I soon found that I was a lot happier when I was dealing with the younger patients.  They seemed to smile a lot more than the adult patients and I seemed to smile a lot more when I was around them.  Eventually, I realized that I was best suited for pediatrics…just like my father, so my Pediatric residency soon followed.

 I value the relationships I have with my patients and their parents.  I enjoy things like calming a fussy baby, tickling a toddler, and talking with the teen about their latest victory.  As a pediatrician, I get to be a part of the lives of children.  How great is that! 


Personal Interests:

I enjoy outdoor activities like fishing, camping and skiing with family and friends.  I like building gadgets in my garage with my welder and I would someday like to design and build my own boat.

I have enjoyed taking part in mission trips providing health care in some very different cultures.  So far, I have been to Venezuela, China, and Mexico.  It has been very rewarding to provide even a small amount of help in other parts of the world with great health care needs. It has also allowed me to have opportunity to help meet some spiritual needs as well.  I quickly realized that the parents of every culture I have encountered so far are just like the parents of our community.  They all really love their children and want the best possible life for them.

Methuel Gordon, M-D- - Palouse Pediatrics


Philosophy of Care:

I share the core values of our group:  compassion, integrity, respect, and excellence.  Every family who comes to our office is important. Using my experience and medical expertise to provide the best care for your child is very important to me, and this is most effective when I provide a nurturing and caring environment where families feel like they are being heard.


Why a Pediatrician:

I knew I wanted to be a doctor at a very young age.  I had a sibling who struggled with chronic health issues, which motivated me to become a pediatrician.  I find great joy in helping children and their families be healthy. 


Personal Interests:

When I am not providing care to my patients, I spend the bulk of my time with my family. We spend much of my vacation time travelling, which is often challenging with younger children, but there’s never a dull moment.  When the weather is conducive, I make good use of local trails on my road bike. I will occasionally carve out time to do oil paintings of landscapes (of which there is plenty of subject matter on the Palouse).

Dr- Katie Hryniewicz - Palouse Pediatrics

Philosophy of Care:

Being a parent is one of the most rewarding jobs on the face of the earth – but man, is it HARD! It is life-changing, frustrating, joyful, terrifying and bewildering all at once. My philosophy of care revolves around wellness and empowerment, ensuring that you get to be the parent that you desire to be, while keeping your child safe and healthy.

I acknowledge there are all kinds of parenting styles that can be successful, strive to honor your relationship with your child, and yet guide with science, well researched standard of care, and experience. I believe in establishing a trusting relationship both in the office and across different platforms so that we can effectively work as a team in the best interest of your child or teen.


Why a Pediatrician:

What if I said it was because they have cuter, less stinky feet than adults? Partly true! In actuality, pediatrics is one of the most amazing fields and I couldn’t see myself doing anything else. Do you realize how much someone changes from tiny newborn to high school senior getting ready to head off to college and the real world? Sure, the medicine and physiology is different (children aren’t “just small adults”), but the social and emotional changes are also never-ending and fascinating. To be able to form relationships through that, and help shape their future, is such a privilege.


Personal Interests:

In addition to being “Dr. Katie” I am also a wife and momma to two girls – and hanging with them is one of my greatest joys, inspirations and interests in life. I’m sure you will hear me talk about them. I also love slow summer days at the lake, hiking, running, enjoying yummy foods and trying out new restaurants, coffee dates with friends, exploring different aspects of personal wellness, and sharing mom and medical knowledge on social media.

Dr .Lee

Philosophy of Care:

I love walking alongside children and families in their journey of growth and development. Meeting a family with a new baby and being able to take care of that child from infancy until adulthood is the greatest privilege of my work. As a doctor, I am dedicated to providing excellent evidence-based care, and partnering with the whole family to understand your child's needs.

Through my training at Seattle Children's Hospital, I took care of the sickest children in the region from Alaska to Washington and all the way through Montana. I was a software engineer before that, and now, I am the father of 4 children at home. These experiences taught me how valuable a trustworthy relationship with your doctor is. Solving complex health needs starts with reliable well-child checkups. My goal is to understand your family's unique needs so I can best care for your child's physical, mental, and spiritual well being. I look forward to supporting you and your children's healthy lives!


Why a Pediatrician:

Everything changes the moment you become a parent. It's an incredible privilege to be a part of that and to watch families grow year after year. I can't imagine a more rewarding profession helping kids to grow healthy, mature, and strong!


Personal Interests:

I enjoy exploring the wonderful outdoors with my wife and four young kids, who seemingly achieve new heights every day. Outside of our home, church and community are great sources of joy for me. Personally, I still find writing software to be a fun challenge, and I'm always looking for ways to use technology to make the world better. I also play guitar and enjoy good food.

MacKenzie Rinaldi

Philosophy of Care:

As I have grown into my physician identity throughout training, I have become both a pediatrician and a mom. Becoming a parent is the hardest job I have ever had! There's no user manual for the never-ending months of broken sleep, toddler tantrums in the grocery store, or the forever runny nose. By incorporating both parts of me, my philosophy of care revolves around supporting individuality and compassionate teamwork. Recognizing the unique components of every family is a core tenet of my practice; what works for one may not work for all, but it's my job to distinguish these different pieces and help brainstorm the best path forward.

Additionally, my job is to cheerlead the team! Supporting parents/caregivers when we cannot handle one more meltdown about the pink dress vs. the purple dress (and bigger conflicts, too), supporting the office staff and nurses who make everything happen, and supporting my colleagues as we collectively care for our community. It is a great privilege to walk alongside families from birth to adulthood through difficulties and triumph together.  


Why a Pediatrician:

I have wanted to go into medicine for as long as I can remember. My mom's cancer diagnosis ultimately helped me decide on human medicine over veterinary studies - though my "why" has largely stayed the same! I'm passionate about advocating for these little beings to become the best versions of themselves, working together as a team to make that happen (working with parents, family, doctors, teachers, caregivers, coaches, etc.) and emphasizing the importance of preventative healthcare and choices to avoid trouble down the road. To play even a tiny part in someone's "growing up" journey is an immense joy!


Personal Interests:

Outside of work, I enjoy gardening, spending time in the sunshine and chasing my two young daughters with my husband, Matt. If you live on Sunnyside, you will probably see my toddler running down the sidewalk in only a diaper and rainboots!

Maricarmen Shields, MD - Palouse Pediatrics

Philosophy of Care:

My main role as a pediatrician is to be a support system for families so that they can live happy and healthy lives! Going to the pediatrician’s office shouldn’t feel like a chore - it should be a time to get a few tips on anything you are struggling with or have questions about, but mostly a time to hear about all of the wonderful things that your child is doing. From the challenges of breast feeding on that first day, to navigating life with a teenager, my goal is to make that journey as smooth and fun as possible!


Why a Pediatrician:

I love working with families and seeing kids grow! I love taking care of all types of kids, but I have a special place in my heart for children with complex medical needs and infants born with club foot.


Personal Interests:

In my free time I enjoy spending time with family, traveling, hiking, and playing volleyball.

Our services

If your child is experiencing a life-threatening emergency, please call 911 or go to the nearest emergency room.

During the well child checks, our pediatricians will evaluate your child’s development, behavior and general well-being. Palouse Pediatrics uses CHADIS, an online system that delivers questionnaires that determine if your child is developing on schedule and without health risks. Our receptionist will send your child’s questionnaire a week before the appointment to fill out. If you forget to fill out the questionnaire please arrive 15 minutes early to fill out your questionnaire upon check-in. Using CHADIS before the visit will help your pediatrician take better care of your child.

We also will address safety in the home, optimal nutrition, toilet training, and environmental concerns.  Our pediatricians will also determine if any vaccinations are recommended during your visit with our office. During these visits our pediatricians encourage parents to ask questions about any concerns that they are noticing in their child.


Here is our recommended schedule of well child visits:

  • 3 day
  • 10 day
  • 2 month
  • 4 month
  • 6 month
  • 9 month
  • 12 month
  • 15 month
  • 18 month
  • 24 month
  • 30 month
  • 3 years and up we recommend a well check every year

Palouse Pediatrics is dedicated to the well-being of all children, adolescents and young adults. Vaccinations are the cornerstones of health and wellness. The family of providers at Palouse Pediatrics firmly believes in the effectiveness of vaccines to prevent serious illness and to save lives. We offer the full range of vaccinations necessary for healthy child growth.

We provide several in-house labs with some results provided during visits. For our patient's convenience, we have partnered with Pullman Regional Hospital to provide more comprehensive testing. You will receive a separate statement of charges for services provided outside our office.

Depending on the type of lab testing your child will be getting done, it may be necessary for your child to plan ahead to ensure that they are able to fast if necessary. Fasting for the purpose of a lab draw means that your child does not eat or drink anything but water 12 hours prior to their blood draw.

  • Newborn Circumcision
  • Skin Lesion Removal/Biopsy

We have an on-call pediatrician available 24/7. If your child is experiencing a life-threatening emergency, call 911 or go to the nearest emergency room.

For established Palouse Pediatrics patients who need to speak with the on-call pediatrician, please call our main office number and listen to the message to find out how to be connected.

Please call back during our normal business hours to put in these requests through our reception staff.

We hope this Health Insurance 101 will be helpful information, however if you have any questions do not hesitate to call our billing department at 509-332-6139.

Please bring your most current insurance card at the time of service as this information needs to be updated to provide you with the most efficient billing service.

Below we have listed the answers to most commonly asked questions. If you need further assistance, please contact our billing office 509-332-6139.

Q: What if my child is covered under an insurance company that is NOT listed. Can they still be seen?

A: YES! We are willing to bill any insurance for you. However we are not contracted with all of the insurance companies. This means that you may be responsible for more of your bill. We do expect $75 dollars upon check in and the remaining at the end of the visit.

Q: Do you offer a discount for patients who pay in full at time of service?

A: YES! We offer 20% discount for patients who do not have health insurance coverage and pay their bill at time of service. We do expect $75 dollars upon check in and the remaining at the end of the visit. Payments are available if you are unable to pay in full, however the discount will not be applied.

Q: Why was I charged for another office visit when my child was in for a wellness check?

A: There may be times when a child needs a service that is not considered preventative on the same day as well child visit. If a child is not well or a problem is found or needs to be addressed during the checkup, the physician may need to provide an additional office visit service (called a sick visit) to care for the child. This is a different service and is billed to your health plan in addition to the preventative services provided that day. If you have a co-payment for the office visits or coinsurance or deductible amounts that you must pay before your health plan pays for these services, our office will charge you these amounts.

Q: How do I know for sure if our doctors are covered under my insurance plan?

A: The best way to know for sure is to call your insurance and ask them directly. We are contracted with many insurance companies so there should be no problem. However, there are times we may choose not to renew our contracts with an insurance company.

Q: I received a statement from you showing that my insurance company has not been billed. Why is that?

A: Most often it is because we did not receive your current insurance information while you were in the office. If you did give us a copy of your card and you’re still receiving a bill, it may be because we failed to link your information to the visit properly. Either way, if you let us know, we can easily correct the problem.

Q: Both parents carry insurance for their child, which policy is the primary?

A: All insurance companies follow the birthday rule. The parent whose birthday falls first in the year will be considered the primary insured. We are happy to bill both your primary and secondary insurance.


Glossary of Billing and Insurance Terms:

  • Applied to deductible: a portion of your bill, as defined by your insurance company, that you owe your provider
  • Co-insurance: the amount you must pay after your insurance has paid its portion, according to your Benefit contract. In many health plans, patients must pay for a portion of the allowed amount. For instance, if the plan pays 70% of he allowed amount, the patient pays the remaining 30%. If your plan is a preferred provider organization or other narrow network type of product, your co-insurance costs may be lower if you use the services of an in-network provider on the plan’s preferred provider list.
  • Co-Payment (co-pay): A predetermined, fixed fee that you pay at the time of service. Copayment amounts vary by service and may vary depending on which provider (in-network, out-of-network, or provider type) you use. The amounts also may vary based on the type of service you are receiving (for instance, primary care vs. specialty care).
  • Deductibles: The amount a patient pays before the insurance plan pays anything. In most cases, deductibles apply per person per calendar year. With preferred provider organizations (PPOs), deductibles usually apply to all services, including lab tests, hospital stays and clinic or doctor’s office visits.
  • Health maintenance organization (HMO): Health maintenance organization (HMO) (refers to health insurance)—these health insurance plans require enrolled patients to receive call their care from a specific group of providers (except for some emergency care). The plan may require your primary care doctor to make a referral before you can receive specialty care. An HMO may require you to live or work in its service area to be eligible for coverage. HMO’s often provide integrated care and focus on prevention and wellness.
  • In-network: A group of doctors, hospitals and other healthcare providers preferred and contracted with your insurance company. You will receive maximum benefits if you receive care from in-network providers. Depending on your insurance plan, your benefits may be reduced or not covered at all if your receive services from providers who are not in network.

Thank you for choosing Palouse Pediatrics for your healthcare needs. You have entrusted us with your most valuable asset, your child’s health. We strive to provide quality care in accordance with your wishes.

As a new patient, we ask that you contact our office first, so that our reception staff is able to build your child a profile. Before you place a call to our office, be sure to have your child’s health insurance card in front of you as we will need the policy number, group number and any copay amount in order to complete the profile.  If you don’t have health insurance or your child has not been added to a health plan yet, no problem, just mention that to the reception staff and they will help you.

Our office is contracted with all the Medicaid plans offered by Idaho and Washington State. In order to start seeing our practice, we will need to be listed as the primary care provider on the card. If you are unsure or need to change this information, please call your insurance company to request this change.

During check-in, we will ask for the following:

  • Current Health Insurance Card - please note that all co-payments are expected at the time of service. If you do not have insurance, please contact our office so we may discuss payment arrangements with you.
  • New Patient Paperwork - If you would like to print off the new patient paperwork, please click on the links in the "Patient Forms" tab below.

To pay your bill online please call 509-332-6139.

We ask that you give us five business days to process your child’s prescription refill request. This allows the physician who prescribed the medication to review your child’s record and call if there are any questions. In order to expedite your request, please contact your pharmacy to have them fax us a request.

All controlled substance prescriptions do need to be called in each month.  Please give the physician five business days to process your child’s refill request. These prescriptions are not available to pick up in the office, they will be electronically sent to your pharmacy.
