John "Jack" Cartwright
Jack joined Metabolic Disease Associates in 2019 after receiving his Master’s degree from Lock Haven University’s PA program. He grew up in Chicago, but has lots of family in Pennsylvania. He did a rotation with Metabolic Disease Associates as a graduate student, and enjoyed it so much he decided to join us full time. Before becoming a PA, Jack worked in market research and consulting for the Nielsen Company. A passion for nutrition and metabolic health research, and a desire to help people lead healthier lives eventually drove him to change career paths. He enjoys skiing, reading, hiking, bikerides, and spending time on Presque Isle during the summer months.
