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.

Dr. Melanie Gray

“I went into medicine so that I could keep working with ballet dancers, but I discovered that my passion is people and families. Every person has an ambition and it is my goal as a physician to help you reach your maximum potential and maintain it throughout your lifetime.”

I am originally from the Seattle area. My first career was as a professional ballet dancer in Boston and Dallas. I completed my undergraduate degree in Biology at University of North Texas in Denton, went to medical school at Rocky Vista University College of Osteopathic Medicine in Parker, Colorado and finished my residency at the UNTHSC-Plaza Medical Center here in Fort Worth.  I enjoy working in a lively family practice clinic and am excited to focus on providing a more holistic, wellness-based approach to your health, medical care and lifestyle!

Although I love being active outdoors, you can always find me in the studio enjoying my dance and yoga classes. I have two young kids that keep me equally as busy with their sports and recitals.  I met my husband the first month I moved to Texas, and we are happy that after 20 years of adventures, we are settled in DFW.
