Meet The Team


Our Physician
Dr. April Guminsky

Dr. April Guminsky has over 15-years of experience working with patients to improve their health.  After graduating from the Medical University of South Carolina, she went on to complete a duel residency in both internal medicine and pediatrics at VCU Health Systems (MCV Campus) in Richmond, Virginia. Dr. Guminsky also holds a Master of Education from Chapman University.  She enjoys partnering with patients to understand their symptoms and find the underlying cause, so they may take control of their health and change their circumstances. 

In 2017, Dr. Guminsky began incorporating Functional Medicine into her medical approach and treatment plans.  With the inherent premise that the body can heal with proper support, Functional Medicine is a lens to medicine based on general principles of function that cross system lines.  For example, an inflammatory process affects the GI system, cardiac system, musculoskeletal system and more.  Today, medicine has been artificially driven into organ systems, like isolated silos, and treatment is mainly pharmaceuticals that further disrupt the natural function.  Dr. Guminsky believes that medication has an important role in medicine, but only in the context of understanding their effects on the entire system.  Often, lifestyle and natural supplements can help restore function, avoiding downstream side effects and further dysfunction.  Dr. Guminsky is an Institute of Functional Medicine Certified Practitioner.  Trained by respected, world-renowned physicians from the Mayo Clinic and successful, acclaimed Functional Medicine practitioners around the world, Dr. Guminsky uses techniques and testing to discover nutritional deficiencies, gut imbalances, systemic inflammation, food sensitivities and more.


Dr. Guminsky focuses on healthy living, disease prevention, optimal function and performance and finding the root cause of all symptoms and disease.  She also understands that the Mind-Body-Spirit connection affects every aspect of a patient’s life, especially their physical health.


Dr. Guminsky has seen how living wellness can change people’s lives, including her own.  She has two grown sons.  She and her husband enjoy traveling.
