Dr. Hastings

Dr. Hastings is passionate about affordable, research-based healthcare. He practices integrative medicine, which combines the best of traditional western medicine and well-researched alternative methods. He specializes in internal medicine, allergy treatment, prolotherapy, and osteopathic manipulation (similar to chiropractic treatments).

An entrepreneur at heart, Dr. Hastings pioneered one of the first Direct Primary Care (DPC) practices in the U.S. in 2008: Doctor’s Health Solution. He is now the founder of 7Health, a thriving DPC practice in Frisco, TX (in the same building as the Family Medicine Plus clinic).

Dr. Hastings was named by Star Local Media as Frisco’s favorite allergist, and Family Medicine Plus was voted as one of the city’s favorite family practice clinics.

Dr. Hastings’ greatest passion is spending time with his wife and family. He enjoys composing and playing his own classical piano music, traveling, and doing humanitarian work with his family.
