Dr. Theriault graduated manga cum laude from The University of Texas at Austin. She attended medical school at The University of Texas at Houston and was selected as a member of Alpha Omega Alpha Medical Honor Society. She completed her Dermatology residency at the University of Colorado. Dr. Theriault became board certified in Dermatology in 2000. She serves as an Assistant Clinical Professor at The University of Colorado and is currently on the teaching facility of Medical Education Resources. She also mentors medical students at the CU Health Science Center as a preceptor, and as a volunteer faculty teaching University of Colorado dermatology residents on Cosmetic Injection Techniques.

Drawn to Dermatology because it is a mentally challenging field, Dr. Theriault finds it very rewarding to diagnose a tough case and implement promising treatment options. She especially enjoys treating autoimmune skin diseases, such as psoriasis cutaneous lupus and pemphigus. Apex Dermatology, now a part of U.S. Dermatology Partners, is involved in clinical research, enabling our patients to receive the most cutting edge treatments available.

Dr. Theriault enjoys the personal relationships that have developed from treating families that she has been lucky enough to care for over her 16-year career. Her philosophy is to treat her patients with compassion and respect, explain the disease process and involve her patients in the healing process.

Dr. Theriault also finds reward in the cosmetic side of dermatology. “I believe that my background in art serves as a good foundation for performing cosmetic procedures as many of them are sculptural. We do not aim to change the patient’s appearance; rather, we are looking to enhance it.”

During her free time, Dr. Theriault enjoys skiing, running, hiking, playing the guitar and enjoying time with her husband and two children. In the community, she participates in free skin cancer screenings, and is involved in philanthropy for children’s programs for those at risk, programs that support the Arts in Colorado and programs that aid the homeless population in Denver.

What Our Patients Say

Alexandra Theriault, MD
5 Stars  I may have been one of her first patients when I moved to Littleton and she took over the practice of the retiring dermatologist, can't remember his name. Squamous cell cancer was removed from my left hand, and later from my right hand. I was so satisfied with her care that I continued to return for all of my skin issues over the past 26 years. I have had many sun damage issues that are all now taken care of. I would recommend Dr. Theriault to any person for dermatological issues. –

5 Stars  First visit/annual skin check. Dr. Theriault was quick, thorough and quite friendly! She made me feel quite at ease! She reacted to my 'out of comfort zone" behavior with grace and professionalism when she performed a quick procedure during this visit!!! –
