In Dr. Carl Thonfeldt’s Own Words

My passion for medicine, the skin, and rural America began as a child. I grew up in Eastern Oregon on a sheep farm, where I watched my father dedicate his life to improving the health and quality of life for the animals by providing for the whole animal. We designed specialized feeding programs and the best medicine and treatments in order to breed championship sheep.

I also personally experienced the challenges of highly sensitive skin. For most of my childhood, I struggled with allergies, eczema, and sensitive skin. I know that for any individual with skin problems, especially a child, the problems don’t affect just the individual; they affect the entire family. So from an early age, I was fascinated by the process of putting human and animal bodies in their best shape possible. It wasn't just about treating, but preventing.

I received my M.D. from the Oregon Health Sciences University, now one of the top two clinical medical schools in the nation. I knew I wanted to spend time in family practice before specializing, because I wanted to be able to focus on the whole person, not just the case. Specialists often become so focused on their one area of specialty that they neglect to view the person as a whole. I later learned that 85 percent of all skin diseases are a manifestation of internal conditions. I spent three years in family practice for the U.S. Navy, then completed my dermatology residency at University Hospital in San Diego, California, now one of the top three dermatology training programs in the nation.

My passion has always been for rural America. When I was in training, I would see a man-power distribution map, which showed there were no dermatologists in the Southeastern portion of Oregon and Southwest Idaho. I believe that people living in rural areas deserve to have access to specialty medicine. Oregon had invested in my education, and I felt they deserved a return on their investment. I have dedicated my career to serving those 110,000 people who live in a 30,000-square-mile area of Southeastern Oregon and Southwestern Idaho.

Within the first year of practicing dermatology, I noticed that there was a trend of people who were not getting well—and not because I wasn't smart enough. An increasing number of patients were unhappy with modest treatment results that did not last, along with the side effects they experienced while using many types of prescription medication. There were a couple of diseases that continued to stump me—conditions known as "winter itch" and "sun allergy" that would come and go no matter what the treatment. I knew there was something deeper to be investigated and resolved. I was determined to figure out a solution that was both safe and effective, and so I put together a research team.

At the time our research began in 1989, the outer layers of the skin were thought to be nothing more than a superficial layer of cellophane. The question our team hoped to answer was, "If we could optimize the structure and function of the skin, could we prevent skin diseases and skin cancer, and possibly even skin aging?" We first had to study the skin barrier, though. After nearly a decade of basic research, we discovered that more than a dozen major skin problems stem from chronic inflammation and disruption of the skin barrier.

In 2002, my team developed a product line, Epionce, that not only helps to calm the damaging effects of chronic inflammation in the skin, but also helps our body naturally repair and fortify the strength of the protective skin barrier. My research and the Epionce products we created help me to be a better doctor for my patients by helping improve their quality of life with higher clearance rates and more prolonged remissions. I started the first medical spa in the Western Treasure Valley: The MedSpa by CT Derm. The purpose was to introduce cosmetic treatments developed by using our medical devices combined in unique protocols to reverse and prevent cosmetically disfiguring conditions. Ultimately, they work together to improve the health of the skin.

My hope is for the people in Eastern Oregon and Western Idaho to know the resource that is available to them concerning their skin and to take advantage of my years of study and expertise. My focus is entirely about the health of the skin, so it can function at its best. No one has to live with the burden of untreated skin disease or ailments, because at the end of the day, everything we do at CT Derm is about improving the quality of skin.

Here is What our Patients Think

All of the interaction with the staff, technicians and doctors have been professional and friendly. The staff is efficient, the wait times are minimal, and the care is exceptional. I highly recommend CTDerm.

Wade W. (Patient since 2019)

I have known from a distance that Dr. Thornfeldt and his staff were very good. But in just one visit, I realize that I had underestimated how good they are. Our son and daughter's skin issues, as well as my own, were not noticed by our dermatologist where we live. It was fully worth the trip from Florida.

Robert H. (patient since 2016)

My experience with Dr. Thornfeldt and his staff has been nothing but pleasurable. The staff are friendly and helpful going the extra mile to meet the patients needs. Dr. Thornfeldt is dedicated to the care of his patients, actively listening and responding as he seeks to see the bigger picture.

Dezra. R (patient since 2019)

The staff at CT Derm is very friendly and helpful. I found the visit very comfortable. Dr. Thornfeldt is extremely knowledgeable, thorough, and understanding. I am a former patient of his from when he had an office in Nampa, but due to improved skin issues and major life changes, -- a divorce and move, I didn't follow him to his Fruitland office. After over 12 years, and new skin problems, I knew it was time make the drive. I trust him completely and appreciate his experience and expertise.
