Working with Boomer was a game changer for me, he helped me learn of the unmaxed potential within me and showed me how to gradually challenge myself until I went from dreading the challenge to embracing it. Working with boomer was both a positive physical and spiritual experience for me. More...

Boomer rocks! A year ago I came to him after not having worked out in 30 years. And year later I have lost near 30 pounds and work 5 times a week. I am stronger, healthier and my diabetes is gone! More...

Boomer is very informative, knowledgeable and passionate about what he does. He motivates others to become there best and teaches you so you can do it yourself and help others later. Great choice!!

I linked up with Boomer after several years of following him on various socials, but using my own guess work to form my routines. After only 1.5 months working with him, I’d say I’m the strongest I have been in that time, as well as the most confident. Boomer brings professionalism and extensive knowledge to the table, but also knows how to break it down to a layman so it’s all easily digestible and applicable. Five stars. More...

When working with Boomer, he has been incredible with showing me and letting me understand what our goals are in getting to our goals. When working with him I've seen a lot of progress in my health and my appearance. A bunch of my friends and family have taken notice that I've slimmed down and put on muscle. He is also amazing to talk to. When working with him, you'll learn good fitness but you'll believe in yourself. The quality and experience that he provides is worth it. More...

Personal Trainers

In my experience personal training can be hit or miss. Sometimes you get a sub par trainer only interested in your money, or you get a trainer who is knowledgeable and actually cares about your progress, Boomer is that guy! He has helped me get out of the tremendous rut I was in and helped me get on track to achieve my fitness goals. This is a man who thrives on people succeeding and flourishing. If you want someone who will get you into peak shape look no further! More...

Boomer is one of the strongest (physically and spiritually) people I’ve been blessed to meet in life. He has extensive training knowledge and is extremely hardworking, which is a great motivator in the gym and life. I’d recommend Boomer as a trainer to anyone willing to put in the work — he pushes hard and gets RESULTS. More...

Q&As

I teach them the benefits of a healthy lifestyle, including but not limited to:
proper nutrition and hydration,
exercise and weightlifting/ strength training,
proper daily habits such as sleep, rest, relaxation,
also focusing on proper mental health, journaling, and treating yourself and your body as something that they are responsible for helping. Your body is an extension of yourself, the vessel through which you interact with the world and others with whom you have a relationship with. You would do well to take care of it.

Hard work and consistency. You must stay focused and keep working whatever plan you have. You could have the greatest plan in the world, but it will not work if you aren't consistent. If you want to look different, lose weight, put on muscle, whatever that goal may be, if you do not train for it, you will not reach your goal. However, the opposite is also true. If you work hard, and stay consistent, you are always 3-6 months from a life changing body.

Making new friends. Every client I have ever trained, we have developed great relationships. It makes sense too, because If I help someone create the body of their dreams, get confident, string and healthy, it makes sense to say I've made a new friend for a very long time.
