He is exceptionally qualified and knowledgeable. He has written textbooks on dermatology and is an expert in diagnosis. I trust his opinion above all others.
Every aspect of my care has been exceptional.
I saw Dr. Dinulos for a routine skin exam during 2016. I waited for over half an hour in an exam room in an exam gown with nothing to read. He finally entered without an apology. The exam last 5 minutes. It was the least thorough skin exam I’ve ever had. He didn’t even check my scalp!!! Then I got a bill for $240 which is the highest bill I’ve ever received for a skin exam. I have a friend who also saw him for the first time and had the same experience.
I've had a skin issues for many years and MULTIPLE Doctors have taken look and could never give me a good analysis of what I should do to correct the problem. Dr. Werchniak correctly diagnosed the situation and provided some "straight talk" about the problem. I appreciated his candor, his level of care, and a nice office staff.
Office and staff are efficient and well qualified. Dr. Dinoulos is an outstanding surgeon, efficient and proper in his demeanor, and thorough in thought and examination. His approach is cordial and shows the fine academic teaching from Dartmouth.
I had my first appointment with Dr Werchniak and I had a very positive experience with everyone in the office. Dr Werchniak asked and answered questions and listened intently. He was kind and had a very nice presence. I would highly recommend him.
