Eddy Dark, DO

Associate Medical Director

Dr. Eddy Dark is a Floridian by birth but got to Texas as soon as he could. He attended Baylor University, where he met and later married his beautiful wife, Amy. He attended the University of North Texas for medical school and Scott and White Hospital for residency in Emergency Medicine where he became board certified. He worked as an ER physician for 8 years before deciding to open his first urgent care in Waco. In the ER he experienced the crippled healthcare system that this country is living through. He saw urgent care as a common-sense answer to many of the healthcare problems and drama. “Why can’t we go back to treating patients how we would want to be treated?” is the driving question to our urgent care clinics. He has partnered with several great medical providers that share this passion for common sense medicine that is served with value and enveloped in integrity.

Dr. Dark lives on a farm in central Texas with his wife of 19 years and his three awesome children. He is passionate about Faith, Family, and Farming. The Darks are active members of Fellowship Bible Church where they love investing in men’s and women’s lives, as well as marriage and family groups. Dr. Dark loves teaching his children the business side of farming and is really proud of their micro-businesses of raising chickens, goats, pigs, and cattle.

Dr. Tony Hill is a rural Oklahoma native.  He graduated from Oklahoma State University then went on to earn his DO from OSU College of Osteopathic Medicine in Tulsa, OK.

During this time, Dr. Hill became involved in the practice of Urgent Care Medicine, in addition to his ER practice. In 2010, Dr. Hill transitioned his practice to full-time Urgent Care and has never looked back.
