A native of Robstown, Texas, John has lived in San Antonio for over 13 years now and considers the San Antonio area to be home. He has been married for 24 years and has two children who are also very supportive and involved in his practice. He has been working as a clinician in various ERs in the Corpus Christi and San Antonio areas for the last 5 years, but has also worked in urgent care and family health settings.
Before becoming a dual-certified Family Nurse Practitioner and Emergency Nurse Practitioner, John owned and operated 7 outpatient physical therapy clinics located throughout South Texas for over 10 years. As a non practicing owner, the challenge and reward of not providing direct patient care was missing, so in 2009 he sold the business and enrolled in school with the goal of becoming a nurse practitioner and opening an urgent care and family practice clinic. When not striving to keep his patients happy and healthy, he enjoys reading, golfing, snow skiing, and traveling with his family. John works in collaboration with Jeffrey Johnson, DO, a family medicine practitioner.
Dr. Jeffrey D. Johnson is a dedicated primary care physician with over 25 years of experience practicing medicine in Texas. Dr. Johnson obtained his medical degree from the University of North Texas. He also completed his residency in family medicine in the Corpus Christi area. For his excellence in leadership, research, and achievement, he received the Chancellor’s Award from the University of North Texas. Dr. Johnson is sensitive to the uniqueness of each patient’s situation and adapts his consultations and treatment options appropriately to accommodate individual needs and concerns. He serves as our Medical Director and Supervising Physician.
