June 23, 2023Andrew R.Verified patient
I was very impressed with the office staff. I was late because l thought my appointment was 2. They called me and asked if I was coming for 1pm. I explained that I thought it was 2. She told me to come on anyway. When l arrived I was greeted with warmth and was made to feel she cared. The doctor apologized for the wait, which wasn’t very long. He listened and answered all of my questions. I must say l was very impressed with the entire visit. I think they won me for a patient.

Doc Rybstein and his team were excellent today. Smooth check-in and everyone he had working for him were excellent. I had a routine check-up and blood work along with an echocardiogram, ekg etc.
I have a follow up in a month and plan on going back every mo until i reach my ideal weight, my blood pressure is down and other levels.
If your looking for a good doctor certainly call Doc Rybstein !

It was great! I been looking for a good doctor since I moved for 2 years now and I finally found one. He is very understanding he listened well and was very concerned and caring.
October 16, 2017Jessica D.Verified patient
Dr. Rybstein and his wonderfuk front desk manager are amazing. I went in for extreme neck pain and I needed an mri asap. They worked very hard to obtain the authorization for the mri and to get me an appointment for the mri just an hour later. Then they set up an appointment with an orthopedic surgeon for me the next day. Also Dawn who draws blood, does sonograms, and other exams does an excellent job and is very friendly. I would highly recommend this medical practice.
