Dr. A is a Board Certified Internist seeing patients in a busling Primary Care Practice established in 2012. With an immense passion for innovating new ways to achieve optimal wellness, he set out to create the IVy several years ago. Dr. A saw that patients just don’t have time for slow recovery, missed workdays, and not being at 100% for their friends and family. It was then that he realized it is equally important to provide a wellness program for patients as it is to manage dangerous health conditions. Soon after, the IVy was conceived and now patients have a multitude of options to improve their wellness even when disease is not present. 


Nothing excites Dr. A more than hearing stories of recovery and revitalization once patients have started to experience the offerings available through the IVy. When we fall into the insurance trap that wellness is one annual checkup with your primary doctor, it becomes difficult to feel your very best. Be your best you now by booking your first IVy appointment now.
