I had the privilege to participate in Garrett Gray’s online interactive fundamentals improv class. Structured as a zoom class, it had tremendous value as a learning experience, which is difficult to attain while not in person. Garrett created a safe environment lending itself to positive feedback and encouraging his students to take creative risks. His knowledge and professionalism were evident in teaching the fundamental techniques and core curriculum of improv. I totally enjoyed the class and walked away with a renewed sense of comedic performance. It was laugh out loud funny!

I have wanted to take a class like this for a long time. After seeing Garrett and his group perform, I signed up right away for his 7-week Improv Fundamentals class in Orland Park when I saw he was teaching. Honestly, I was nervous in the lead up to the class, but Garrett did such a great job of breaking the ice and making us comfortable to learn. Our group laughs so much during class and we have really bonded. If you have ever considered trying improv or want to learn to be an active listener and get out of your shell, I HIGHLY recommend taking Garrett’s course! You won’t regret it!

The 2020 ‘Fundamentals and Characters in Improv’ course, taught by Garrett Gray was one of the best things I’ve ever done. Humor is tough, but Garrett makes it easy, and I am little bit funnier because of him. It taught me to how to safely run with scissors.

Garrett’s online improv fundamentals course kept my improv skills sharp during the pandemic. No longer performing with my previous improv troupe, I was elated to take Garrett’s class because it helped me keep my reps up and keep my improv skills sharp!

Garrett Gray’s 7-week Improv Fundamentals Class was incredible. Garrett’s teaching style is fun, constructive, and always supportive.  His positivity is infectious. Your confidence grows with each class – from the activities and games that are designed to build on what you learn from week to week, to Garrett’s words of support during class, pointing out things you did well or were funny between classes, and to the amazing group of classmates who support each other and have a ton of fun with each week. I strongly recommend this class for anyone interested in challenging themselves and having a ton of laughs while they do it!

Mike Banker

I had an extraordinary experience in Garrett Gray’s IMPROV class. I took his 7-week course because I had to do more public speaking in my work. The training and coaching I received from Garrett went far beyond my expectations. It DID help me in my work, but in addition, the IMPROV experience had a huge impact on how I observe the intricacies of life now. I became more aware of body language, listening to others, timing, and above all… HUMOR! We-students always left our IMPROV class smiling, laughing, and feeling happy. Hey, this could be the solution to World Peace! I highly recommend taking any class that Garrett Gray teaches. It is rare to have a great teacher…Garrett Gray is one!

Garrett’s 7-week improv class in Orland Park has exceeded my expectations.  As a Toastmaster, I signed up thinking it would help elevate my public speaking skills and in just a few sessions I realized the training provides so much more.  I am learning how to be more present in the moment, how to actively listen, how to respond freely & authentically and how to make meaningful connections out of ordinary interactions.  The laughter filled environment created by Garrett and my fellow classmates allowed me to let go of my fear of failure and to simply have fun with the exercises.  Garrett’s teaching style is perfectly paired with improv too because he is enthusiastic, genuinely supportive and encouraging at both the individual level and to us as a team.  I highly recommend taking Garrett’s class to anyone looking for a unique opportunity for personal development.

Garrett’s improv course is the best around! So much fun! And, unlike many other introductory improv courses that focus on the very basics, Garrett will teach you the true fundamentals of performing improv. It’s taught in a very easy-to-learn manner, yet the course felt like an advanced improv class.

Garrett initially introduced me to improv through Yes and And Toastmasters, and when I found out he was doing a 6 week Improv course, I jumped at the chance to learn even more! I highly recommend his Improv classes to the novice or the experienced Improv performer, because either way, you’re guaranteed to learn a lot, and have a blast!

Garrett’s improv class has “improv”ed my skill set and made life better! Signing up—I just wanted to improve the skill of speaking on my feet. And yet this class has been so much MORE! Not only do you learn to think and speak on your feet but you also learn object work to enhance communication, and active listening which in turn helps build relationships and leadership skills. And did I mention we laughed in class—A LOT—even out to the parking lot. Every night I drove away from class, my face would hurt from all the laughs and thinking about all the fun we had. Outside of class, I began seeing the new skills at play and a lightness of laughter and intention show up in other areas of my life. No need to go to Second City—Garrett’s an awesome improv instructor! He’s not only Second City trained but closer to home! He provides a safe space to learn, grow in different skill sets, and laugh. He also creates a culture that inspires, empowers, and encourages each of his students in their journey. I believe anyone can improve with Improv. I challenge you—don’t hold back—this class will change and “improv”e your life!

Garrett’s guidance not only honed my improv skills but also instilled a newfound confidence in me both on and off the stage.
