Dr Ruymann was very attentive and explained all my concerns with great care expertise. An excellent Doctor Highly recommended.

★☆☆☆☆ 1.0 Carol Montana · Jul 2023

Nurse practitioner cold, unfeeling, couldn’t care less. Because it was above her knowledge she got angry. I can’t tell you how much it hurt me to know my “doctor” just wants people with an easy fix that they can hand a prescription to. At least drug companies should like these kinds of doctors! Over her head I guess so she got angry like I was wasting her time. Is this the medical person you want😭

Doctor RUYMANN was a blessing from heaven.. We were in Cape Cod for the summer when my husband became ill. After a few false starts we ended up in the emergency room. They took some tests and highly recommended doctor RUYMANN to do a procedure to find out the cause of my husband's illness. Within a couple of days we were in the Cape Cod hospital meeting doctor RUYMANN for the 1st time When John Had his scheduled Procedure. Even before we got the results from the biopsy back the doctor recommended that we go back to Florida and begin to lineup some Doctors.He recognized at that point that it might be cancer He was right. There is no doubt that it was the right thing to come home. Though we miss doctor RUYMANN. Anyone would be blessed to have this doctor Thank you doctor RUYMANN

Dr Ruymann was wonderful. Explained my issues so I could understand fully. Even drew a picture so I had a good visualization of what was going on. Incredibly compassionate office.
