Strength & Metabolic Health Coach

Member, The Menopause Society

I am a Houston-based Strength & Metabolic Health Coach who works with women in perimenopause and individuals using GLP-1 therapy. Both transitions require adjustments to strength training, recovery, protein strategy, and everyday habits. I combine evidence-based strength programming with movement assessments, metabolic health coaching, and recovery strategies to protect lean mass, improve strength and bone density, and help you succeed in this stage of life.

The Missing Piece in Fitness Programs

Strength training is one of the most effective tools for preserving muscle, maintaining bone density, improving metabolic health, and supporting healthy aging, especially during perimenopause and while using GLP-1 medications.

However, many people work hard in the gym for years without realizing that mobility restrictions, muscle imbalances, recovery deficits, balance limitations, and movement compensations may be limiting their progress. The value of coaching is not simply providing exercises. It is identifying the specific areas that need attention, prioritizing what will make the biggest impact, and adjusting the plan as your body adapts.

That is why every client begins with a foundational assessment. We evaluate strength, mobility, balance, posture, body composition, and metabolic health to identify opportunities for improvement and build a program around your specific goals and needs.

The result is a more personalized approach that helps you build strength safely, protect lean muscle mass, improve movement quality, support bone health, and continue making meaningful progress over time.
