Scott Sorensen
"Len helped me immensely after my rotator cuff surgery. Very professional and a great guy. Can’t recommend him enough!"

John Hooper
"I have some post injury and surgery issues that he not only works around but works on after the training. Len doesn’t push you but rather makes you want to push yourself. I’ve never felt stronger in my life and I’m turning 64 this summer!"
"My Back Finally Healed!"
Nicholas Colletti
"Len is hands down the best. I came in wanting to build strength and improve flexibility but had no idea what I was doing in the gym. He not only helped me get stronger but also gave me the confidence to train on my own. More importantly, when my partner threw out his back, Len’s cupping therapy and stretching techniques had him walking normally again the same day—and with continued practice, he healed quickly."
