“Our experience with Coach Harrison has been tremendous! One of his great attributes is that he demands excellence from every one of the kids and it transfers over to how they practice and play on Friday nights. The skill and technique that he teaches is on the college level, when his kids go to camps or Coaches see their film, they stand out from the crowd, as they have been taught and trained by the best Oline Coach in the area...bar none!”

“Ahmarion began training with Coach Harrison before there was HOLD. Coach Harrison has worked diligently and patiently with Ahmarion. I have really seen a tremendous improvement in Ahmarion’ foot work and overall performance as an offensive lineman. I appreciate that Coach Harrison has pushed Ahmarion to reach his full potential not only as a football player but as a young man. I am well assured that Coach Harrison has Ahmarion’s best interest at heart. I would not have any other trainer for my son. Coach Harrison resonates the true definition of “ you don’t have to be related to be family “. “

“Since starting to work with Coach Harrison and H.O.L.D, my son Wesley has dramatically improved his technique and understanding of the complexity of offensive line plan. Not only has Coach Harrison given him the tools he needs to thrive, he has given him the confidence he needs to excel at his position. In addition to the outstanding coaching and training, my son has matured as a player and as a young man along side fellow linemen from different schools, backgrounds, and levels. This is a family and everyone is completely invested in each other’s improvement and success. We look forward to being active members of H.O.L.D for as long as Wesley plays the sport of football, through high school and beyond.”

I was sold at that moment. Coach Harrison is dedicated to developing the skills of offensive linemen.”

“David Harrison is a guy who studies the game of football. He was a great player, and is a natural leader.  When he decided to become a football coach, I knew he would be exceptional. For the last 10 years, he has studied not just technique, he has become a teacher, mentor, and motivator. His genuine concern for others makes him an ideal choice to teach young men, and not just the game of football, but life skills as well. He knows what it takes to become a complete offensive lineman.”

“David Harrison is one of the only two-time captains I ever had in 15 years as a college head coach. His passion and work ethic as a player was truly unparalleled. He became a strong student and a very detailed offensive lineman. I am so pleased that David is now taking the time to mentor and teach young offensive lineman. “I am sure these young men will greatly benefit from David’s excellent knowledge, attention to detail and communication skills and as a coach”.
