Dr. Geller is personable and has genuine concern about medical issues. He is very helpful with working on medical issues. I have been with Dr. Geller for many years and have been very happy to have him as my doctor.Providence Patient
dr geller is a great dr. knowledgeable, kind and caringProvidence Patient
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.Providence Patient
Dr Geller is SUPERB!!!!!Providence Patient

Very pleased with health care service at this pointProvidence Patient
did send RX to pharmacy now airing to get RX resent so i can get it filled. RX for US of thyroid wasn't sent Hx of US with prior facility that has evaluated thyroid for 10 plus years.Providence Patient
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.Providence Patient
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.Providence Patient

Dr Geller is the finest doctor I have ever had in my 70 years. He REALLY cares about his patients. He spends ample time with them AND he listens carefully. ANd he follows up. He even called me personally to review lab work that my non-Facey rheumatologist ordered, because Dr Geller saw a problem in the blood test results of which I had copies sent to Dr Geller. HE IS OUTSTANDING!!! and he's a nice guy too :-)Providence Patient
