I had my first visit to Prima Medicine today (4/24/21) in Fairfax). I was enormously impressed with all aspects of the practice: very cordial and professional receptionists and secondary medical personnel. My one-hour appointment with certified Nurse Practitioner Rena Kalter revealed a thoroughly dedicated and caring medical professional who possesses extraordinary expertise and a delightful personality. As a full-time college professor, I would award the grade of A-Plus to the entire Prima Medicine team!

I went to Dr. Haritha Yalamanchilli for the first time at Fairfax Office. Timings were perfect not so long wait. She was examined me for the first time so she listened to my concerns very carefully. No rush no watch time checking. Her patience is the key and she advised me some medications and test for further investigation. Will recommend 100% to anyone who is looking for a good Family practitioner.

I have been seeing NP Surin Rodino since we moved to Fairfax. She is kind, thorough, and listens. Wait times are usually well managed and often have availability to get you in when needed.

I was able to schedule my appointment very quickly, receptionist was so kind and understanding of my situation. They ask you to text them when you are in the parking lot so you don’t have to wait in the waiting room at all. Dr Curtis was so nice and took time to listen to everything I wanted to discuss and did not rush me at all. She explained everything in detail and really put my mind at ease. Love Prima Medicine!
