Sports Performance Nutrition

Athletes have many coaches for their sport, and these are all “energy out” coaches. I'm the "energy in" coach, and I'm excited to partner with our "energy out coaches" - trainers, fitness instructors and coaches. The body is just a machine and the better the fuel the better the output.

Obtain an easy-to-follow nutrition plan to help you look and feel your best. Small changes, big results. You can still dine out, bring food in, travel and enjoy your favorite foods and make changes that will be with you the rest of your life.

Why Nutrition consulting with glen?

There are many types of “nutritionists”. Every Registered Dietitian (RDN) is a nutritionist, but not every nutritionist is an RDN. Completing a weekend course results in a nutritionist title, but only after a 4-year degree, 900+ hours at an accredited hospital, and passing a standardized test can one be called an RDN.

Glen’s education, a Master’s Degree in Clinical Nutrition from New York University, being a certified specialist in sports dietetics (CSSD), 26 years of experience, being a Fellow of the Academy of Nutrition and Dietetics, and down to earth manner set him apart from his peers; “Perfect does not exist, if you shoot for it you will always fail,” says Glen of his approach to weight management and sports performance optimization through nutrition. Glen believes in making changes in your daily eating as part of your lifestyle. Restriction is not the answer to a lifestyle change, but balancing nutritious meals in a timely manner, as well as proper hydration and sleep play a critical role in achieving success.


“There are no bad foods, just degrees of better.” Weight management is all about calorically cheapening the meals you are eating; cheesecake is not bad, it is delicious … but [calorically] expensive. Carrots are much cheaper! The quality of the food is also an important component that he customizes to each client/athlete.

Glen teaches, guides, and monitors his client’s adherence with optimal ratios of macronutrients; proteins, carbohydrates and fats. His meal plans are designed to maximize satiation and energy output from meals, incorporate hydration programming, and improve sleep (not just duration, but rather when and how deep an individual’s sleep patterns are).
