Why We Built A2Z
Dr. Mark Shank, DO, FAAEM began his career as an emergency nurse in 2001, became a physician in 2009 and achieved board certification in emergency medicine in 2015. With over two decades on the frontlines of emergency care, he understands firsthand the toll that stress, long shifts, and poor habits take on the body - and what it takes to truly change.
​
Together with his wife Dr. Colleen Shank, DO, MPH, FAAEM - a board-certified physician with expertise in emergency medicine, public health and exercise physiology - they built A2Z to give patients what they wished they'd had: real medical expertise, real personal support, and a program that fits your actual life.
