Lou Ferrigno, actor, author, “Mr. Universe”
I have known Brian for several years and over these years I have come to find out what a very genuine person he is. He genuinely cares about his clients emotionally, physically, spiritually and mentally and this care he has shows in his clients. His caring and compassion, makes him in my eyes, a genuine human being. I am Happy to be his friend.

Kevin Sharer, CEO, Amgen
Brian has changed my life. His programs work, and his passion is infectious.

Bill Toomey, Gold medal decathlon champion, 1968 Olympics
I was introduced to Brian at age 68. I had not been able to do any form of strenuous exercise or practice running for more than 18 years. During my visit to Brian’s Institute, I was first evaluated and the information that was ascertained along with my medical documentation allowed Brian to design a program that would include two sessions for two weeks and a meal plan that regulated my hormonal balance. Unbelievable, is all I can say. In two weeks I was transformed to a time years ago when I happened to be training for the Olympics. The net results after this challenging session was a complete transformation- my markers told the story. After being measured I was astonishing. Brian was able to set my physical age to a time decades ago and the final joy for both of us happened when he urged me to sprint. Tears of joy streamed down my face when through the “Theiss Miracle” I was reborn as a runner… as neurotransmitters sent messages throughout my body. I had received the ultimate reward a body that now had the capacity to perform at the highest levels and the net results was that I felt not 68 but youthful, happy and physically competent. ‘It was the Theiss Miracle’.

Bill Austin, founder, CEO, Starkey Laboratories, largest hearing aid manufacturer in U.S.
I humored my wife and went to the Theiss Institute with absolutely no intention of taking any of it seriously. The last thing I expected to find there was someone who actually knew what they were talking about and would motivate me to make exercise a part of my life. Brian Theiss did both! He is a man I have come to respect, trust, and believe in with my longevity. Straight facts and results are all I had time for, and Brian delivered!

Dr. Sal Aria, co-founder & executive director, International Sports Sciences Association, team doctor for the USA track and field team
Brian’s facility and his programs get the best results in the shortest amount of time, and have been scientifically and medically proven. He works with physicians every single day in ways that other trainer only dream of.

Freddie Ravel, #1 recording artist, composer
’We are going to do greatness together!’ These were the very first words that Brian Theiss uttered in our first handshake! His passion, purpose and sincere heartfelt interest in people is legendary, and he shined his light and gift on me form that moment on. It is said that ‘knowledge is power’ but when it is combined with heart, you have a master. Brian embodies this mastery in his expertise in transforming people from overweight, tired and out of shape to glowing beings who are truly empowered. I know, he put me on his program and I am more alive today than I ever have been. I am honored to call him my health advisor and colleague but more importantly, I am blessed to call him my friend.

Marty Albertson, Chairman, CEO, Guitar Center
Thanks for the new. Putting lean back into my life takes a whole new meaning after working with you. Give me one more!

James F. Little, Chairman / President & CEO, Employers Direct
Brian, as you and anyone that really knows me – I am a man of little words. When I was first introduced to you and your program, I thought to myself…’if this kid can produce a fraction of what I’ve been hearing about him, for me, I’d be amused.’Since I’ve known you over these many years – you have turned my amusement into admiration and respect. You and your program did not impact my life. It actually saved my life. You are truly a man of great action, and it has been my pleasure to watch you save so many other lives. My family and my business all thank you for giving me back my life.
