December 23, 2025Steven C.Verified patient
My second appointment this year with Karina. She was quick to judge. In the 15 min appt I had, I was called neurotic and told I should see a psychiatrist for my menopausal acne. She said I was “picking” at my face. She does not even know me, would not listen and raised her voice talking down to me. Literally a 15 min appt. I came for help, not to be spoken to this way. I told her I was not going to argue with her. A absolute horrible experience this time.
I left the office in tears and will never be returning. Zero stars for Karina!
Nothing like any of the other reviews I’ve read. Unbelievable, I will never return to this office.

August 4, 2025Sherrill P.Verified patient
The receptionist was lovely. I witnessed a disgruntled older gentleman raise his voice to her and she handled him like a champian. It was impressive! This happenewd about 7:30 am today.
Karina was outstanding in every way!!! Thank you!
July 14, 2025Susan L.Verified patient
She was great! I had to bring my 2 young kids with me, and she was very attentive and sweet to them. Normally bringing kids to an appointment can be a little chaotic, but she was very friendly and accommodating to the chaos. She was great and so sweet.
December 19, 2018Jessica W.Verified patient

Karina was extremely supportive, professional, and skilled. She explained the procedure I was about to have and frequently checked with me during the procedure to make sure I was comfortable. She explained what I should expect afterward and answered all of my questions. I’m really glad she was recommended to me!
