Coach G

My name is Gaspar Reza, proud owner of Optimal Gainz performance. I am grateful to say that I have been in the fitness space for close to a decade. Working with hundreds of clients from all backgrounds of fitness, helping guide and achieve their fitness goals.

I specialize in strength and performance, function strength, injury prevention, and mobility.

My goal as your strength coach and owner of OG Performance is to not only guide you in accomplishing any fitness goals you have in front of you but to educate and give you the pure confidence of lifting and training.

Coach Mari

My name is Mariam Shawish but you can call me Mari (Mau-REE)! I’ve been working as a personal trainer and group fitness instructor for the last 4 years. I am currently working on getting my Bachelors Degree in Exercise Science and Masters in Nutrition.

I love training Brazilian jiu jitsu, strength training, and spending my time with the people I love. I became a trainer for a very simple reason- to help people on their fitness journeys at whatever point they are at.

Fitness to me isn’t just about working out- it’s about taking care of your body, mind, and soul. I started lifting in high school yet I really got into heavy lifting 6 years ago when it felt like everything was out of my control. Getting into lifting heavier weight and seeing how that changed my body- helped me realize how much control I have in my own life. My strength and confidence grew while also leading me to so many opportunities in life! I hope I can help others do the same


Coach T

My name is Taylor Hanberg, one of the NASM-CPT on-site coaches here at Optimal Gainz Performance. I’m the owner of Fitness Tailored LLC, an online fitness coaching business, and I’ve partnered with OG Performance to offer 1-on-1 personal training to round out my all-inclusive client experience.

My fitness career began in 2011, when I worked as a personal trainer while pursuing a bachelors degree in human performance and sport and a minor in nutrition. In 2018, I began offering online fitness coaching, helping people worldwide dramatically transform their physiques and overall quality of life. 

As a coach, I specialize in women’s body composition change, muscle building, and fat loss, and am committed to helping you establish sustainable lifestyle habits. Your health is my top priority, guiding every decision regarding your cardio, resistance training, and nutrition programming.
