What I love is the access to telemedicine feature. The simple stuff like my refills can be done through telemedicine without a need to come in in person. Love it.

Both doctors or very nice and compassionate. And take the time to explain everything that is needed for you to be healthy. Wait Time is very short 90% of the time. I have been with them for over 10 years. I was 36 at the time. I'm still here.

It was great; found them online, scheduled appointment online and was seen that same day, by the medical doctor! First floor, free vallet parking. Friendly staff. Inexpensive. Happy to recommend to anyone.

Dr. Witten at Ninth Avenue Internal Medicine is an excellent Medical Doctor. He is very professional and has a wonderful disposition. I appreciate having Dr. Witten as my Primary Care Physician. He is thorough, proactive, patient (I didn't feel rushed), and sincere. And yes, he has a great sense of humor.

Dr. Borisov has been my primary care physician for a couple years now and he has done a superlative job. He always takes the time to listen to my concerns and makes a point to ask how my girlfriend is doing, how work is going, and things like that. He isn't just making small talk, he genuinely cares. Everyone else in the office is very helpful as well and they all seem to work together very well to make sure that I receive the best care possible.

The PCP that is saw for over 10 years retired and I needed to find another primary care physician. Upon recommendations, I chose Dr. Daniel Witten to help me manage my health. I made a great choice. Dr. Witten cares about me as a patient. He asks questions to get to know me and better understand my health. He is so smart and quickly figures out how to fix any problem. Dr. Witten is also very funny. He cracks jokes and is just a great guy. The staff at this office is incredible. I have always been able to get an appointment within a day or two after calling. The nurses and technicians are just fantastic. Prescription questions and problems are taken care of quickly -- just leave a voice message. I highly recommend 9th Avenue Internal Medicine and Dr. Witten.
