Consulting Dietitian

Abbie is a Registered Dietitian, and Certified Specialist in Sports Dietetics. She became a Dietitian after her uncle spent time in hospice battling cancer. After his passing, Abbie started volunteering with hospice patients, being a member of the birthday brigade (singing happy birthday to hospice patients). This is when she saw, first hand, the effects food brings to someone and how nutrition affects everyone’s life.

Abbie attended Pennsylvania State University, studying nutrition while running for the Cross Country and Track & Field programs. Through the vigorous training, injuries, and successes, she personally knows the pressures that athletes face mastering their sport. During her time at Penn State, she learned the effects that underfueling and proper nutrition can bring on someone.

Her mission is to improve the nutritional habits and behaviors of endurance athletes to optimize their health and performance for the long run. Also to avoid the mistakes she made: not fueling appropriately, ignoring the symptoms of amenorrhea, and avoiding food groups. Nobody has time for stress fractures.

Abbie has worked with Olympians, National Champions, and simply amazing athletes. Her resume includes Red Card Athletics, University of Florida, University of Tennessee, University of Oklahoma, and University of Buffalo.

She knows how to provide realistic nutrition solutions to athletes of all levels and would love to help you meet your goals!
