William L. Epperly, MD, FAAFP 

Dr. Epperly has been a board certified family practitioner since 1985.

He received his M.D. degree from the University of Illinois College of Medicine, and completed his family practice residency at St. Joseph Hospital in Chicago where he served as Co-Chief Resident.

He is affiliated with Northwestern Central DuPage Hospital, although his practice is exclusively office-based. He is a certified Clinical Nutritionist, a Fellow of the American Academy of Otolaryngic Allergy, a Fellow of the American Academy of Family Practice, and a member of the Christian Medical and Dental Associations.

Dr. Epperly has also received special training through courses and seminars in the areas of functional medicine, allergy, hormone therapy, and clinical nutrition. This has enabled him to become enormously more effective in dealing with thyroid issues, hormone issues, low testosterone, autoimmune disorders, chronic fatigue, fibromyalgia, menopause, arthritis, bowel problems, and many others, while being able to rely much less on drug therapy.

As an evangelical Christian, Dr. Epperly believes that good health is a blessing from God, and we are to be good stewards of the bodies we’ve been given. He tries to encourage his patients to pay strong attention to their spiritual health, and enjoys praying with anyone who so wishes.
