My Philosophy and Approach to Wellness...

As your private physician, my goal is to develop a partnership with you and provide highly personalized healthcare that emphasizes wellness and prevention. After working in internal medicine for over 23 years, I have come to appreciate the importance of taking a holistic approach to treat and prevent illnesses by focusing on nutrition, exercise, stress management, and spiritual wellness. Through my affiliation with MDVIP, we will have additional health resources available to us and I am able to dedicate more time to each of my patients, giving us the flexibility to develop a close relationship and create a personalized wellness plan.
For over two decades, I have been practicing in Oneida, New York and have established personal relationships with numerous specialists in and around the area. I work closely with them to ensure quality care. I have privileges at Oneida HealthCare and am able to visit you in the hospital. By communicating and coordinating your care with the hospital physicians, I can make your transition as smooth as possible.
My number one priority is to help you achieve your desired health goals and provide the best care possible for you.

About the Practice/Practice News

Change is significantly affecting the healthcare landscape with ongoing implications for doctors and patients. It’s nearly impossible to navigate such a complex system alone, but with me as your ally, we can get through it together and keep you on the path to optimal health.

The best healthcare starts with a physician partner who truly knows you, your needs and your goals. In my MDVIP-affiliated practice, you come first. Third parties and red tape will not interfere with my ability to care for you the way you deserve.

Testimonials from patients of Dr. Ratnarajah

from cynthia in NY March 15, 2020 for Daniel M. Ratnarajah, MD

I have been a patient of Dr. Dan's since roughly 2009. I couldn't ask for a better doctor. He has helped me in sickness and he has helped me with my personal life as well. I couldn't ask for a better doctor as well as a friend that does his best to give his patients the best care and advice. I only wish the payments were a little less as I seem to struggle with them.

I am a healthy over-50-year-old. My weight is in a relatively normal range and I exercise moderately. I don't drink or smoke. That said, I take full advantage of Dr. Ratnarajah's services. In today's busy world, we are getting very accustomed to instant gratification through technology.

from Eileen in NY March 11, 2020 for Daniel M. Ratnarajah, MD

I recently relied on his wonderful expertise though I was 1000 miles from him. We discussed the nuances of a health problem and came up with a solution. He ended the call reminding me I could call at midnight if I needed him. Thank you! 🥰
