About Us

WellFast Urgent Care Center was founded in 2006 by Emergency Medicine physicians with a vision: to provide high quality health care to patients presenting with unexpected minor illnesses and injuries in a friendly environment, without long waiting times, and for a reasonable fee. Five years and two clinics later, we have grown to offer a variety of services encompassing urgent care, occupational medicine, and physicals to the Lawton/Ft. Sill community and the surrounding areas. Our clinics are staffed by Emergency Medicine Board Certified physicians, Advanced Registered Nurse Practitioners, and Physician Assistants who bring a wealth of experience to treat a vast range of minor conditions that do not require in-hospital care and can be worked up, diagnosed and treated (most of the times) during a single encounter. Serving busy people with busy schedules who have limited time to spare for doctor’s visits is our specialty. With digital X-rays and labs on site, we provide a one stop shop to address your ailments and get you back to enjoying life. We get you in, out and well fast!
