Our team



As a type 1 diabetic for 20 years, Alejandro always wants to show that no matter the circumstances or conditions, people can reach the best physique of their lives with his knowledge in nutrition and exercises. He always loves helping people achieve their fitness goals.



Weight training has been Monica’s passion since the age of 15. She has always been athletic and played sports throughout high school and college. When she moved from Venezuela, she remained active by becoming a personal trainer. Her goal is to teach others how to be active and stay fit! She tries to live by example and make an impact on her clients’ lives every single day.



Jose loves helping his clients achieve their personal training goals. He strongly believes that together we can create a healthy lifestyle and the body we want.



Rachel is a NASM certified personal trainer who has a “mind over matter” mentality that she translates into her workouts. Her goal is to push you, hold you accountable, but still be a supportive, attentive, and caring coach.



As someone who went from underweight to healthy, I want to show clients that lifting and a healthy lifestyle are essential to living a full, happy life no matter their body goals. My goal with each client is to push them to be their best selves, support them through the process, and to hold them accountable as they reach those goals!
