Background

I am a Registered Dietitian Nutritionist (RDN), Certified Strength and Conditioning Specialist, NSCA-Certified Personal Trainer, and Tactical Strength and Conditioning Facilitator. As a proud Marine Corps veteran, I bring a disciplined yet empathetic approach to helping clients transform their health through personalized, evidence-based care. My clients can expect clear, actionable strategies to achieve their goals while building sustainable habits that lead to long-term success.

My passion for this work is deeply personal. Over the past decade, I’ve lost over 40 pounds, maintained that loss, and become stronger and more fit. This transformation not only improved my health but gave me the confidence to join the Marine Corps, excel at the highest level, and pursue graduate school to become an RDN and CSCS. Watching my parents struggle with preventable health issues—losing my mother to cancer and helping care for my father—further inspired me to change the trajectory of my family’s generational health. Today, that mission drives me to help others achieve their own life-changing transformations in health, fitness, and quality of life.

I’ve had the privilege of helping clients sustain significant weight loss for over a year, proving that lasting change is possible with the right approach. I’ve also worked with Marines to maintain height and weight standards, enabling them to serve honorably and continue their military careers. Whether it’s building a solid foundation for better health or achieving performance goals, I’m committed to guiding my clients with the same focus and dedication I’ve applied to my own journey.

Outside of my practice, I stay active through strength training, Brazilian Jiu-Jitsu, shooting, and golfing. I also value spending quality time with friends and family, which helps me maintain balance and connection in my life. My journey—from personal transformation to serving in the Marine Corps and building my private practice—reflects my belief in the power of discipline, education, and resilience to create meaningful and lasting change.

If you’re ready to take charge of your health and improve your quality of life, I’m here to help. Together, we’ll build a foundation for confidence, vitality, and fulfillment that will serve you for years to come.
