Dr Tieman listens to your concerns and addresses them with professionalism and friendliness. He will explain what you do not understand. He helps keep you calm when you feel scared or not sure what procedures entail. I have been trusting in his expertise, services, and practice for over 10 years.
It was all over before I new it.
Dr. Tieman was very nice, helpful, and supportive
Dr. Tieman detected some Basal Cells on my nose, and referred me to a Mohs surgeon to have them surgically removed. Throughout my recovery, Dr. Tieman has been very attentive to my healing, and is always pro-active about skin screenings. Aside from his medical knowledge, Dr. Tieman is compassionate and always patient with my numerous questions. I wouldn't go to anyone else! Thank you, Dr. Tieman!
Been here a few times, always polite, prompt and proffessional.
He is helpful, listens, and works with me well
dr. tieman is great
Dr Tieman is very professional and takes the time to answer and address my questions. I have been seeing him for a few years now and recommend him without question.
I am so thankful Dr. Tieman is knowledgeable about treating Ichthyosis, which is a condition that I have. I recently met someone who was having a hard time finding a dermatologist that can treat her husband who has the worst form of Ichthyosis. I am so thankful for Dr. Tieman treating me all these years.

great provider

quick and professional

When looking at my face to meet the public, I first find it necessary to cover up a "scraping" done by this dermatologist to take a biopsy some years back. So far I have found no way to cover the blemish left behind. The scraping done was benine, it Was fast, did not hurt, done in less of second. But, there had been no explanation as to what results would be. He just had said he would scrape and scraped. If your appearance is important to you I suggest you not see this dermatologist.
