I found the SB Dermatology staff to be helpful , friendly , and efficient. I waited only a few minutes for my appointment with Dr. Siamus. She was also very friendly, thorough, and professional. She listened to me, and addressed my concerns with solutions that were thoroughly explained. It was a very good and productive visit!

★★★★★ 5.0 I O · Sep 2025

I find the staff to be extremely professional. It's the first doctor"s office I had been recently where patient were attended to within a reasonable timeframe. I received immediate attention at registration and was triaged within a short time of sitting waiting to be seen by the doctor. Dr Siamas was quite professional, yet warm and welcoming. I absolutely appreciate the service and care from the time I entered the office until I left. Excellent standard if service which should be replicated through the medical industry.

★★★★★ 5.0 Lois Kilkenny · Oct 2025

Dr Siamis is the absolute best. I look forward to seeing her annually and she always educates us, is extremely thorough and has a lovely demeanor. The entire practice is wonderful, working very hard to meet standards that are uncommon in busy large practices. Top notch facility.
