If you're struggling with sleep disorders like insomnia, restless leg syndrome, and sleep apnea, we can help. Treating sleep disorders is no different than treating any other medical problem. After a thorough consultation, patients who have clear indications for diagnostic sleep studies will be referred for an overnight study, followed by a personalized treatment plan. Recommendations may include medications prescribed by your physician, or non-drug approaches by a sleep psychologist. We strive to help you understand the nature and treatment of your sleep disorder, and partner closely with your primary care physician to provide a comprehensive ongoing treatment plan. 

Our Sleep Center Lab is part of an elite group of facilities that are nationally accredited with the American Academy of Sleep Medicine.  Highly trained board-certified sleep specialists conduct sleep studies upon physician referral.

Usha Nandhini-1

Philosophy of Care:

Core values of my medical practice include individualized, patient-focused care integrating physical and emotional well-being with compassion, empathy, and respect. I believe in forging genuine and unique relationships with patients, their families to gain an in-depth understanding of the complexity of their ailments with dignity and sensitivity to make informed health care decisions while valuing their core beliefs. I trust that open communication and effective listening to the patient's needs and desires are paramount in providing quality care. I wholeheartedly believe in making each patient feel important in my clinic and leaving a positive impact on their lives.

Personal Interests:

I would call myself a food enthusiast, as I love exploring food experiences including, trying new restaurants, diversifying my taste buds with different ethnic food. I have an innate curiosity to know about food origins and history. I would love to travel more in the future - Italy is on top of the list. I appreciate different cultures and experiences, and traveling is a way to feed that desire for me. I watch plenty of travel and food shows - favorites would include "Parts Unknown by Anthony Bourdain, Somebody feed Phil, Rick Stein's Journey to the Mediterranean and Greek islands."
I also love to read books, mostly non-fiction nowadays, on mindfulness and Buddism. Fiction books that interest me are mostly thrillers, murder mysteries, and suspense novels.
When I am not feeding my stomach or soul, I like to hike, walk and hit the gym for a spin class.

Why did you decide to pursue Sleep Medicine?

An innumerable amount of people in this world suffer from sleep disorders, affecting their health, relationships, longevity, and daily functioning.

A negative sleep pattern arose during my internal medicine residency when I fueled my tired body with caffeine and quick naps. Compounded with the jet lag I experienced due to frequent travel, I became fascinated by my sleep cycles and the complexities of sleep disorders and was drawn to study them further. My own experience made me realize that quality sleep plays an essential role in the human body’s optimal functioning, and depriving the body of rest impacts one’s emotional and physical wellbeing.

I sincerely believe that good health begins largely with good sleep. I am passionate about educating individuals on the importance of quality sleep as a prerequisite for a healthy life and eager to treat sleep disorders to help them achieve their optimal health.

Dr. Usha Nandhini at Palouse Sleep Medicine is great! She helped me identify what sleep issues I was having - sleep apnea. Right now all CPAPs are on back order and Dr. Nandhini has been great with giving me information to hold me over until I can get my machine. Thank you to the whole Palouse Sleep Medicine team!
