Testimonials + Reviews

Since both of my boys began working with Christian their improvements in skating have been very noticeable. My boys each play high level hockey (NCAA D1), and Christian does an excellent job challenging the two of them, all while making their time on the ice an enjoyable experience. I would recommend Christian to any hockey parent looking for a knowledgeable and dedicated coach to improve their players skating.

“It’s the opinion of my wife and me that Christian Grunnah is an exceptional skating coach and person. He genuinely cares about the development of the kids and is always willing to go the extra mile in order to help them improve. In my years of taking my kids to rinks, I have never met an instructor who possessed the combination of the unique qualities of personal decency, kindnesses, patience, knowledge of how to help kids develop properly as skaters, combined with the ability to motivate his students to achieve ability levels that they-themselves did not believe they could achieve. Not only has my son benefitted from Christian’s instruction and guidance, but he has also become a better person in the process, just by being around him. We are grateful to Christian for all he has done to help our son Sean in every way.”

There are many guys who claim to be skating and skill coaches. They find nice videos on-line from prominent skill instructors across the globe and replicate their drills. Things look good on the surface. But they are not. 

Unfortunately most of these instructors don’t know the core techniques and are unable to break down a player’s form down to do things the right way. 

The result is their students end up doing what look like nice skill drills, but the player is replicating the wrong form over and over. 

Christian is the complete opposite - he understands the core technical aspects of skating and puck handling and can break a players form down so they have the proper technique and efficiency to their game. 

Most importantly he loves teaching and has a passion for the game. This is regularly on display in his interactions with his students as they make strides in developing their skill set and achieving their goals.

"Christian’s expertise is in teaching explosive, multidirectional, and neurologically-challenging edge work and agility. Each skill is progressively taught with a high-speed, masterful demonstration, supplemented by unparalleled clear-cut age/skill-appropriate verbal instructions. Coach Christian is a positive role model and consummate professional who actually cares about passing down his extensive hockey knowledge & life-lessons to younger generations. My son smiles ear-to-ear every time he comes off of the ice from a GPS lesson because he enjoys being pushed to his limits and developing his confidence."

—D.A. Molloy


“We were looking for real improvement in our 2009 son’s skating, and it was evident from the first skate with Christian and GPS, that this was someone who could make a huge impact on our son. It’s been close to a couple years now working with Christian and the results have been dramatic. Not only has his skating and speed improved dramatically, but his overall skill level has also followed suit and resulted in great success on the ice. If your child wants to become a better, faster and complete hockey player this is the path.”

My son has done drop ins, hockey schools, camps, and private lessons on a regular basis with Christian for over a year. They have all been phenomenal and touch on many aspects of the game. I have noticed an enormous change with my son’s speed and agility along with his confidence to play the game. I attribute this all to Christian and GPSpowerskating. Christian is as good as it gets. He’s pleasure to work with and his techniques and attention to detail are unmatched.

I’ve never seen a coach with so much passion on and off the ice. My son absolutely loves working with Christian . Coach Christian will take your player beyond the next level.

GPS hockey was very organized and run in a very professional manner. All the coaching staff was thoroughly prepared and very familiar with all drills and breakout sessions. This aspect really separated themselves from other camps. My son improved and really enjoyed the camp!! I would highly recommend it to any player looking to take their game to the next level.
