What are our clients saying?

One of the most important things about Andrew is that there is only one promise made.  It’s not about being an elite player, obtaining a baseball scholarship to the university of your choice or making a certain team.  The promise is that a player will get as much out of the lessons as (s)he is willing to put the attitude and effort into each lesson.   As the players buy into that, it’s amazing how it transcends ball into other areas like school work!!

Thank you, Andrew.  Mark’s success is a testament to your efforts as much as to his.


Andrew and the staff at PPA are top-notch! Jacob has been training there for 6 years and whether it is learning a new pitch or fine tuning mechanics, the Hithouse has been instrumental in his development.


Andrew is very professional, works hard with you and always pushes you to your fullest potential. You won’t ever be disappointed! Been going to Andrew for over 4 years.


Andrew and his team offered a professional teaching style that incorporated great technique for a young player to become successful in hitting, fielding and pitching.  At the same time providing a fun, safe and inviting environment for the players to come together as a team in the off season.  I would and have recommended Peak Performance Athletics to every team in my own organization of Halton Hills and in the COBA loop.  Continued success to PPA and thank you for all of the success you have brought to me personally, my coaching staff and especially the players that you have trained over the years.


Andrew has always been so amazing working with Colby over the past 7 years. His guidance and advice has also been very helpful. He truly cares about everyone who works with him.

Cortney’s 1-1 sessions with my daughter are always well planned and have changed throughout the years to match her developmental level. These sessions have kept my daughter at the TOP of her game!


We are heading into our 3rd season with The Hithouse. We have been so thankful for all the sessions with all of the trainers – I think our son has pretty much worked with them all and I cannot say enough great things about the positive atmosphere The Hithouse creates for baseball athletes. Today my son worked with Jose and again it was a super positive 1 hour training experience to help yield results on the field. See you again tomorrow!

My daughter has been a regular client at Peak for several years.  The positive atmosphere and encouragement from all the staff at Peak have and continue to motivate her to excel both offensively and defensively.  She recently committed to a school in the Southern States and without a doubt it was the instruction she received at Peak coupled with her desire to reach this goal.  Her performance on the field as well as her coachability is a direct result of the superior coaching she received at Peak Performance.  I would strongly recommend any child interested in fastball/baseball should go to Peak it will truly be the best investment in their future as Peak kids standout in every way – ability, performance and attitude.

Recently our daughter Kael committed to a university in the US on scholarship to play softball and it would not have been possible without the elite level instruction and mentoring by Cortney.  Our daughter has worked with Cortney for the past 7 years and we cannot emphasize enough how invaluable her coaching has been. Cortney is a qualified, expert instructor who, having the experience playing at a D1 university, knows what it takes to get to the next level. We are very impressed by her vast knowledge of the game and that she constantly networks with colleagues to learn the latest information and techniques.


Massimo was so happy to be back! He said it was “like we had never been gone”! The way that everyone greeted him and remembered him made him feel great. Especially on a day when he was feeling a bit down! Being there tonight totally lifted his spirits as per usual when the Hit House is involved
