When I went to the doctor for a rash he looked at my rash and went I’ve never seen that before and just prescribed me random medicine, just seemed very unprofessional because other dermatologists have been way more thorough and in depth

Today was my first time being seen by Dr. Roger Karlin as my new primary doctor. He matched my energy, so did all of the staff. Dr. Karlin listened to everything I spewed on about (I'm a hypochondriac lol) so he's obviously a great listener. The nurse was so nice and calming when she had to withdraw two vials. The wait time was probably 1 minute. Overall great experience.

Dr. Roger is a great doctor because he gets right to the point and doesn't try to make small talk with you and waste your time by beating around the bush. I would recommend this doctor, although the charisma and welcoming to the office by the desk lady wasn't that warm as I would expect but rather dull and not with much energy. The nurse had more charisma but she also lacked in that area I would say. Even so though, my visit was pleasant and relaxing and I definitely would come back for future appointments.

I saw doctor Karlin for an annual physical, just having moved to a new area. I had an excellent experience with Dr Karlin and his staff! Highly recommended.
August 13, 2021Joyce B.Verified patient
Listened well and didn’t make me feel rushed.
July 5, 2021Matthew D.Verified patient
This was my initial visit. I explained my reasons for wanting to affiliate with a CT doctor and my concerns today. Dr. Karlin was a very attentive listener. He changed my blood pressure meds and he made a recommendation for an arthritis specialist. I have an appointment with him soon for an annual physical. I look forward to a long relationship with Dr. Karlin.
