Insurances accepted
Baylor Scott & White has established agreements with several types of insurance to ensure your health needs are covered.
Insurance listings are subject to change without prior notice.
Please call your physician's office or your health or insurance plan to verify coverage information prior to scheduling your visit or procedure. Not all members participating in contracted networks have "in network" access. In network participation may change from time to time without prior notice. Independent providers (which could include, for example only, anesthesiologists, radiologists, pathologists, emergency medicine physicians, advance practice professionals, and other independent providers of health care services) may deliver part of your care, and such providers may be considered out-of-network on your health and insurance plans even if the Facility may be considered in network. If you desire additional information as to the providers who may be involved in providing your care, you can either ask your treating provider (who may know some of the specialists or groups who could be involved) or you can request a list of Facility-based physician groups by calling the following toll free number: (877) 810-0372. This list is updated annually and is subject to change without prior notice.

Patients appreciate
Dr. Mark Thieberg consistently receives exceptional praise from patients for his thoroughness, professionalism, and expertise in dermatology. Patients repeatedly describe him as knowledgeable, experienced, and meticulous in his examinations, with many noting his ability to detect skin cancers and pre-cancerous conditions early. His communication skills are highly valued—he explains procedures clearly, takes time to answer all questions, and never makes patients feel rushed. Many reviews emphasize his caring, patient-centered approach and describe him as friendly, personable, and genuinely interested in his patients' wellbeing. Patients appreciate that he listens carefully to their concerns and involves them in treatment decisions. His efficiency is frequently mentioned, with patients noting he is consistently on time for appointments while still providing comprehensive care. Many long-term patients have been seeing him for 10, 20, or even 30+ years, with several stating they drive long distances specifically to continue receiving his care.
Patients also share
While the overwhelming majority of reviews are highly positive, a small number of patients mention areas for improvement. One patient felt the visit was somewhat rushed and that Dr. Thieberg did not provide adequate post-procedure instructions for wound care after facial treatments. Another patient noted he can be "all business" and doesn't always respond to humor. A few reviews mention that he can sometimes be delayed for appointments due to his busy schedule, though most patients indicate he apologizes for any delays and that the wait is worth it. One patient commented that while competent, Dr. Thieberg lacks a warm bedside manner and doesn't fully explain procedures or follow-up treatment, though this appears to be an isolated perspective.
