ABOUT Nutrition For Performance

Our mission is to provide individualized, tactical strategies to improve your overall performance through nutrition and lifestyle modifications. We offer private consultations, public presentations, and other avenues of education to present the most recent, evidence-based nutritional practices to put you on a path towards success.

We firmly believe that true results require a TEAM approach. What do we mean by TEAM? “Together Everyone Accomplishes More.” That is what we want for you – to accomplish your goals and more. We work as your coaches, but you are the captain of your championship season. Just like any team captain, your commitment to consistently improve is key to the success of your overall performance.

Antonio “Tony” Castillo

Tony’s journey began as an overweight middle schooler. This continued throughout high school until he decided to jump on a “diet.” Unfortunately, this resulted in unsustainable weight loss. His weight fluctuated in college due to lack of nutrition knowledge, but this inspired him to understand how nutrition played a role in the human body.

Enhancing performance through nutrition every day

Tony’s passion today is to teach others how healthy lifestyle modifications optimize performance in ALL areas of life. After working at the University of Florida and then with the Toronto Blue Jays, Tony focuses on helping you to become an elite performer. Being an elite performer in your field can take many forms, whether you’re the owner of an investment firm or a professional athlete trying to become an MVP. Tony’s plan is to teach his clients how to sustain their weight goals without counting calories or macros.

Tony graduated from Florida International University in Miami with a B.S. in Biology, B.A. in Chemistry, and an M.S. in Nutrition and Dietetics. He is credentialed by the Academy of Nutrition and Dietetics as a Registered Dietitian. Tony continues to hone his practice and regularly mentors with colleagues and professionals such as Tony Stephan, RD and The Dietitian Mentorship program

And did you know? Tony’s parents are from the Dominican Republic, and Antonio is fluent in both English and Spanish.

Karen Baldree

Karen is a registered dietitian with over a decade of experience.  She is licensed in North Carolina, South Carolina, Georgia and New York.   She graduated from Georgia Southern University and completed her internship with the Georgia Department of Public Health. 

She has spent many years helping both children and adults alike make the best food choices.  She seeks to view the family as a unit and try to cater to the family needs as well as the individual.  Karen holds both Nutrition and Food Science degrees.  Her degree in Food Science helps to direct clients to choose the healthiest and tastiest alternative.  She is certified in adult weight.  She is very well-versed in food allergies and feeding problems for all ages.  She had worked extensively with women and children throughout her career addressing issues such as prenatal nutrition, postpartum weight loss, newborn feeding intolerances and childhood picky eating habits. 

Karen’s approach to nutrition counseling is based upon two principles.

First, small, attainable goals add up to meeting large goals.  When you celebrate the small accomplishments, you feel empowered and motivated to continue.  Before you know it, you see lasting changes.  Secondly, let’s be real.  If the food doesn’t taste good, is too expensive or it’s what you like, you aren’t going to benefit at all.  Being real and looking at your tastes, lifestyle, and preferences is the only way to succeed.  

In her spare time, Karen enjoys spending time with her awesome husband and two beautiful children. She also enjoys cooking, gardening and traveling.
