With many of its core members still interested in training with Chris, he took that as motivation to open EDGE Fitness & Strength in March of 2013 with the help of his sister.

That fact now comes to fruition as he and the EDGE Fitness staff are able to help changes peoples’ lives for the better through fitness and strength training.

Favorite Quote:

“But He said to me, ‘My grace is sufficient for you, for my power is made perfect in weakness.’ Therefore, I will boast all the more gladly about my weaknesses so that Christ’s power may rest on me. That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.” 2 Corinthians 12:9-10
