I have worked with Theresa several times, for special events, meeting goals with nutrition while also working out. Recently though I had a big change in my life and rotated a couple meds that messed with my metabolism and gained weight quick, that was out of my control, until my body adjusted. I had never been through anything like that before. So I started working with Theresa to come up with the right plan to get back my “normal” weight for me. I was the highest I had ever been and so uncomfortable. My diet to lose ended up being different than it was before. I just metabolize differently now, but once we found the right path, I am happy to say I am 3 lbs out from goal. She has taught me so much about food over the years that will forever change choices I make. I am so grateful she was there to help me through this more difficult time. If you are unsure. Try it! You will learn a lot and reach your goal! More...

Working with Theresa has honestly changed my life! I feel very strong! Now at 56, I am in better shape than when I was in my mid 30s. In addition to amazing workouts Theresa has given me amazing nutritional advice. I have lost 39 pounds since January 1 of this year. You are an incredible answer to prayer Theresa!
Thank you! Thank you! Thank you!

I loved working with Theresa. Bi began working with her in 2011. I was at such a low place. I did not have skills for designing my workouts, or knowledge about how to design eating plans that worked for my body nor did I have positive thoughts as I worked out. I was inconsistent and had too much fat for my body. For 1 year I worked with Theresa. She came to my home, trained me, designed personalized training plans, eating plans and while I was working out would always say, “You can do anything for 10 seconds or 30 seconds!” She encouraged me to complete cardio on the day she was not with me and did not chastise but kept teaching and encouraging why it was important to be consistent. Within a year I had lost all my back fat I was down 3 sizes, I was stronger and more positive. I continued to work with Theresa through 2013. She partnered with me to create a training program for teachers at my school that she and I led together she taught me more tricks of the trade to the point that by the time she was no longer able to train with me at my school I was flying! I was training others, I had created and after school training class for my teachers, I was working out consistently and my mindset and body were healthy. I will forever be grateful to Theresa. She changed my life. Now 11 years later, I am doing everything she trained me to do and so much more. Thank you Theresa for teaching me, training me and caring. More...

Very unprofessional. I received a phone call from her, paid for an initial consultation. Explored her beliefs/principals as soon as I got off the phone and those did not line up with my current beliefs so I requested a cancellation and refund which was denied. Paid for a consultation that never happend. More...
