Client Testimonials


"Dr. O'Connor has worked with me since my sophomore year at Notre Dame to the present.  I was 14th pick overall in the NBA draft for the Golden State Warriors. His training and professional advice has been great for my game & I strongly recommend that any young player trying to go to the next level use his training system!" 
- Troy Murphy #1, Golden State Warriors NBA (Currently #3, Indiana Pacers NBA)


"Dr. O'Connor has been great for me,  his dedication and motivation for what he does is out of this world.  Not only is he helping me tremendously to get back to playing football but he is also just a great guy to be around.  With our ongoing improvements every day there's no doubt in my mind I will come back playing football physically and mentally better than ever."
- Rob Petitti, NFL Football Player


"When building a winning program you need to surround yourself with winners.  John's experience, work ethic, passion and ability to bring out the best in others is second to none.  He certainly is a key component in our strive to be a top women's basketball program in the east."
- Stephanie Gaitley, Head Women's Coach - Monmouth University


"Dr. O'Connor has worked with my program over the past 5 years getting them prepared for our highly competitive game schedule.  His program was an integral part of our program's success, which includes over 50 division 1 athletes and other scholarship players. My advice to any athletes or coaches is to sign on to the XCEL program to achieve optimum results in
speed and strength, and to minimize injuries!"
