Our Multi-Disciplinary Approach
to Your Successful Health Journey
Two Experts. One Comprehensive Strategy.
The Clinical Foundation
Juan M. Ramirez, RDN, CPT, B.S.
Juan is an experienced Registered Dietitian Nutritionist and a Certified Personal Trainer who translates complex nutritional science into a safe, data-driven plan for your specific body and health and fitness goals. Unlike general nutritionists, Juan can clinically interpret your bloodwork, manage chronic conditions, and ensure your diet doesn’t interfere with medications. Juan will filter through the “fad diet” noise and create a sustainable, evidence-based eating and nutrition strategy that actually works for you and your busy lifestyle. He can also create custom fitness programs that you will love to keep you active and healthy!
The Behavioral Edge
Lilian Leyva, M.S., BCBA, PN1
When knowledge isn’t the problem—consistency is. Lilian is a Board Certified Behavior Analyst and certified nutrition coach who specializes in the rigorous science of habit formation and behavioral change. Lilian helps you deconstruct the environmental and emotional triggers that lead to “all-or-nothing” cycles. By applying functional behavioral assessments to your daily routine, she works alongside Juan to ensure your clinical plan is actually sustainable in the face of stress and a demanding career. Lilian provides the high-level accountability and mindset shift necessary to turn discipline into a permanent lifestyle, helping you master the psychological side of health for long-term success.
