About
At Crossbridge Direct Primary Care, Dr. Zachariah Overby delivers family medicine to individuals, families, and businesses across Greenville, SC and the surrounding upstate region. He keeps his patient community small so he can know each member personally and respond to their specific needs. Standard appointments run 30 minutes, and same-day or next-day scheduling works in most cases. The practice also offers appointments before or after typical business hours and on Saturdays.
Crossbridge DPC carries a wide clinical scope, from annual wellness visits and sports physicals to vasectomies, joint injections, and auricular acupuncture. Dr. Overby also holds specialized allergy training and offers allergy testing with sublingual immunotherapy drops through Allergy Choices, using the La Crosse Method Protocol. This service extends to non-members as well. Business memberships allow Dr. Overby to visit employers directly at their workplaces, and he makes house calls for patients who need them, including elderly patients in assisted living or skilled nursing settings. The practice currently operates a waitlist for new patients.
