After finishing my visit with Dr. Geller, I was asked to wait in the lobby for my blood work. After I spent about 1/2 an hour, I found out that the nurse never checked me in to the lab even though she told me she did.

Doctor seemed a little too laid back. Hard to get information out of him. Didn't offer any meds or cough syrup.

11/27/2019
I thought the doctor was very knowledgeable. However when I left the appointment I asked the nurse if I would get a summary of my vitals my way my height and some of the referrals and things we talked about. She said "Dr. Geller doesn't do summaries". I thought she was kidding. But when I looked at my chart online there is no summary at all of my visit. And I find that annoying because I won't have a reference point next year of progress.

Dr. Mark Geller has been my doctor for more that 15 years and we followed him over to Facey Medical. The new office is very efficient and seems very organized. It is also very easy to get all test results, as they are sent to me via email notification. Dr. Geller is a wonderful doctor and I would highly recommend him. If he doesn't have the answer, he tells you and then calls you back when he has the answer.

Dr. Geller has been my endocrinologist for a long time but this was my first time seeing him at Facey. He is kind, never makes me feel rushed, listens and explains and keeps an eye on issues that could turn into a problem if not monitored.
100

06/13/2019
I always enjoy coming to Facey, and enjoy discussing medical info & my specific health concerns with Dr. Geller. He's great. I find him to be very knowledgeable, appropriately caring, and very thorough with his testing, since he's aware of the problems I've had with my thyroid, hormones, other concerns & imbalances over the years. The receptionists are very nice & helpful, as well. I'm happy with my choices & services here, and would gladly schedule all necessary specialists here, as well. I'm now looking for a Dr, and to schedule a colonoscopy, as it's been several years since my last one. I haven't had any negative experiences here. I like the facility, as well. The person, who drew my blood was a bit uncareful, however. I have never had a butterfly needle hurt until this blood draw! And, I'm a bit queasy about needles, so it wasn't a great experience, but was over quickly, thankfully!Thanks.
