Our Practice

Simon-Williamson Clinic comprises 36 providers, mostly primary care (Internal Medicine, Family Practice and Pediatrics) with a number of other medical and surgical subspecialties. With so many specialties under one roof, our team is equipped to provide medical care for a wide spectrum of health issues. We maintain collegial relationships with other specialists who may be participating in your care.

Our History

Founded in 1935 in north Birmingham, Simon-Williamson Clinic, P.C. is named after our two founding visionaries, Harold E. Simon, MD and Byrn Williamson, MD. In addition to forming Birmingham’s first group practice, the doctors initiated a philosophy expressed as “not just treating the sick, but caring for people.” In 1975, SWC moved from Norwood to the campus of Princeton Baptist and we’ve been based there for over 40 years. Over the years, despite the changes that have taken place in medicine, the clinic has remained committed to the philosophy and purpose of serving and caring for people. In 2007, the Clinic moved into a new 113,000 square foot building on the Brookwood Baptist Princeton campus and have since been able to expand the range of medical services that we provide.

Our Services

SWC has on-site state of the art diagnostic facilities and on-site physical therapy. Our welcoming new building includes spacious reception areas and large windows, and we provide free wireless internet access for all patients and visitors. All of our physicians are Board Certified or eligible, ensuring the most advanced care for our patients. Our extensive services include:


Most lab tests can be performed in our own CLIA-certified laboratory. Reference lab tests are sent to the appropriate lab by daily courier.

We provide Digital X-ray, mammography, CT, and MRI. We also perform bone density, ultrasound, cardiac echo, vascular, and nuclear medicine studies.

Health Screening
We perform many other screening and diagnostic tests, such as EKGs, cardiac monitoring, spirometry, and TB skin testing, and give injections of medications and immunizations.

Information Technology

SWC has used fully computerized medical records for years. We provide free wireless internet access for our visitors. Ask us about signing up for the Patient Portal for secure and encrypted access to your health information and email communication with your SWC providers.

Same Day Appointments

Our Primary Care physicians (Internal Medicine, Family Practice, Pediatrics) are usually able to see established patients as work-ins for urgent issues that day. Additionally, our pediatricians see urgent care work-ins on Saturday mornings. Call us first before heading to an urgent care center — we’ll get you taken care of.

Hospital Facilities

Our physicians maintain privileges at several area hospitals, including Brookwood Princeton Baptist, Brookwood Baptist, St. Vincent’s, and Children’s of Alabama.
