Simon-Williamson Clinic Joins Complete Health

80-year-old clinic joins fastest-growing primary care group in the Southeast


BIRMINGHAM, Ala., October 19, 2021 – Simon-Williamson Clinic has joined the Complete Health family of primary care practices as the organization continues its growth in Birmingham and across the Southeast. Simon-Williamson is the largest primary care company by patients and providers to join the Complete Health group. Simon-Williamson has been caring for patients in Birmingham for more than 80 years, and accounts for an additional 34 providers joining the Complete Health team.

Becoming a part of Complete Health provides additional resources to continue to provide excellent patient care in a privately-owned, physician driven company independent from larger health systems and insurance companies. Complete Health practices include those formerly known as Birmingham Internal Medicine Associates, Northside Medical Associates, Deerfoot Internal Medicine and Adamsville Family Medicine. Complete Health now has more than 110 health care providers, 700 employees and 16 locations caring for more than 150,000 patients in Alabama and Florida.

Complete Health is a physician-driven, value-based primary group dedicated to improving patient health outcomes, patient (customer) service, and keeping people out of the hospital through high-engagement and easy access to primary care for patients.

“We are proud to add Simon-Williamson Clinic to the Complete Health family,” said Jeff Preuss, CEO of Complete Health. “Simon-Williamson has a long history of caring for the Birmingham community, and we intend to continue its legacy.”

Doctors Harold E. Simon, M.D. and Byrn Williamson, M.D. founded the Simon-Williamson Clinic in 1935, and the clinic is now headed by President Dr. William Kirby, M.D. and practice Vice President Joseph Wu, M.D. The clinic has grown to provide expanded primary care services including hematology/oncology, ophthalmology, gastroenterology, urology, podiatry, rheumatology, pediatrics, OB/GYN and diabetes education.

“We are honored to join forces with Complete Health,” said Dr. Kirby. “We look forward to building on our purpose of caring for our community and strengthening our position in the market as a leader in primary care services and resources.”

Complete Health offers a unique, industry-leading concept in patient care – dedicated care coordinators and member support representatives who educate and address concerns of patients, reducing the stress that often comes with accessing the right health care, benefits, and services. Complete Health will offer same-day visits, convenient hours, and special programs for seniors.

Complete Health is a physician-driven, professionally managed, technology-enabled primary care group delivering excellent quality support services and patient health outcomes. The group based in Florida has practices in metro-Birmingham, Alabama and metro-Daytona, Florida, with growth plans across the Southeast. Complete Health builds on existing practices to embrace value-based care concepts, reduce physician administrative burden, and focus on patient care and quality outcomes – all while lowering the total cost of care.
