Our Providers




Rachel L. Holzhauer, PA-C


Rachel believes in a collaborative approach to treatment, so she is committed to find an individualized plan for each patient. Her goal is to find a treatment approach that best fits with where the patient is at, understanding that medications may not be the right fit for everyone. Rachel completed both her Bachelor of Science and Master of Science in Physician Assistant Studies at Philadelphia University. Once completing school, she became a nationally board certified physician assistant and licensed to practice medicine by the North Carolina Medical Board. Rachel relocated to the Charlotte area and started working on an inpatient psychiatric unit. While she enjoyed being a part of the hospital team, Rachel also found she enjoyed practicing on the outpatient unit as she get’s to spend more time building a relationship with each patient. She has experience working with behavioral health patient’s that are inpatient, outpatient, in intensive outpatient programs, and for emergency psychiatric evaluations. As a provider that believes all systems are linked, mentally and physically, she enjoys keeping up-to-date in all areas of medicine. Rachel also believes in the importance of ongoing education and for this reason precepts physician assistants students from Wingate University and Thomas Jefferson University.
