Dr. Grabowy asks the right questions and provides easy to understand feedback

All is very good with riverview medical associates folks. However, I don't like how i can't call them do directly any longer. It's such a hassle to go thru the larger parent company and leave a message that I have to change the date of my appt. I've needed to speak directly with someone several times in the last year or so and always have to leave a message with the larger company phone team. That's not good service imo.

Dr Grabowy took over the practice from our wonderful Dr [last name]. While we deeply miss Dr [last name] Dr Grabowy has been amazing to work with.
