Just an FYI - I donate for Doctors day in honor of Dr Grabowy each year. Being able to see the provider you need to see at the time you need them is critical to good health care. Availability of a provider makes such a difference when something is wrong, not emergent, but more important than "we'll see you in 3 weeks". I was fortunate to have been able to get a shorter term appointment and received the care needed and am now recovering before the original appointment offering. I owe this to Dr Grabowy and the staff at his office.

Dr GRABOWY is extremely thorough and easy to understand. He takes the time needed to and really cares about my well being. I've recommended him to several of my family and friends. He's the best! The staff is very helpful, professional and polite. I can't say enough great things about this medical group.

Excellent- since I hadn't seen this provider in 6 years, there was a question as to whether I was still considered a patient. But, the front desk was helpful in understanding my concern and booked me an appointment foe the following week- much appreciated

Excellent service.

The doctor answered all the questions I had. Was referring to his notes on the computer to the previous conversations we had. Was very knowledgeable about my case.

The only complaint I have about the visit is when I called to schedule it, I was told there were no appointments available until December and I needed to see Dr. Grabowy shortly. While Roxanne, who was his assistant, said she would email him, I said no, I would. It turned out I did get the appointment the next day. But there needs to be provisions where Dr. Grabowy does see people on an urgent basis, even if they're in, in addition to his regular scheduling, whether it's before or after hours. That's the only complaint that I have. I do think Dr. Grabowy is an excellent doctor. Thank you.

I've been with Dr. Grabowy for a very long time. I wouldn't go to anybody else. He knows me really well. When I do, he does a colonoscopy. He knows exactly, you know, my body.
