Providence Patient
A+ Visit
Providence Patient
I met with Dr. Geller for the first time and he was great and everything about my visit with him was great. More of a general feedback for Facey is that it feels like patients are double/triple booked with providers so there is always a wait time when waiting for you provider to come to your room or even be seen.
Providence Patient
Dr. Geller is a very caring and knowledgeable doctor.
Providence Patient
Dr. Geller was very kind, respectful and informative during our appt. I however waited over an hour to see him which apparently was due to miscommunication with the receptionists. I was on time to my appointment and was not seen for over 60 mins. Dr Geller and his assistant were both very apologetic about this mishap.
