I’ll start with the staff. The entire group at the derm group in North Wales was hands down excellent. From start to finish of my surgery, the entire team was incredibly considerate in ensuring I was comfortable and keeping my mind at ease. In addition, they were very timely in returning any calls regarding any questions I had, as well as following up on received results. Onto my dermatologist Alexis. Alexis is one of the best individual people I’ve dealt with in the medical field. She was truly exceptional in performing the excision and was constantly checking in to ensure there was no discomfort, answering all my questions, and addressing any of my concerns. Her performance was what I would describe as the complete opposite of trash. I would recommend her to anyone. My only recommendation for improvement would be to allow the staff to select the music played in the office. I don’t doubt it would be appreciated by staff and customers alike Thanks so much to the team at the North Wales Derm Group

Very nice office and quick appointment. I called a couple other dermatologists and they couldn’t take me for months. I think I found my new dermatologist

My son is being treated for acne with isotretinoin (Accutane) by Dr. Stierstorfer. I find Dr. Stierstorfer to be thorough, knowledgeable and encouraging. I have also taken my elderly parents to him and easily give him 5 stars.
