As one of the founding members of Team Quest and Xtreme Couture MMA it is with great sorrow that we say good bye to Robert Follis. Robert was a friend, coach, mentor, and philosopher of martial arts to many of us. It is with a very heavy heart that I write this tribute to a man that touched so many. Death is like the sun. There is no escaping it. It infuses every part of our lives, but it doesn’t make sense to stare at it too long. That becomes a real challenge when someone you know, love, and respect ends their life. This is where Robert has been since his brothers passing a couple years ago and where we are left now. It is very easy to get caught up in the urgency that comes from the limited span of our lives. It can push us to obsess over life’s meaning in the time we have. But obsessing over it, and staring directly at it too long can blind us to the possibilities of living. Robert was a Hero to many. Heroes have the whole earth as their tomb . . . There is, enshrined in the chest of every person he touched, a record unwritten with no tablet to preserve it. It’s that which he imprinted on our hearts. What lives on is not what is engraved in stone monuments, but what he has woven into the lives of others. Those who have lived with us become a part of us. We honor the dead by living their values. Through our efforts, we ensure that the good things they stood for continue to stand even when they are gone. Robert stood for many good things. Let’s let Our actions become a living memorial to Robert Follis. R

Robert Follis you will be missed! These little speeches people take for granted. As an teacher and student I will always remember and learn what you have taught. #youwillbemissed #rip #xtremecouture #follismma pic.twitter.com/NMHTSOhmRo

You don’t realize how much of an impact you had on my life. A good coach is so much more than someone to teach techniques. Through the darkest moments in my career and life you’ve helped me see the light and keep pushing. I thank you for everything and apologize for everything more. The next gold belt is for you.

I just heard the news of Robert Follis' death.

I knew Robert from the beginning of his MMA career and transition to coaching. He has always been a kind and supportive person and I have enjoyed a long friendship with him

Heartbreaking. You will be missed my friend.

Absolutely awful to hear that Robert Follis passed away 😫 That man helped a ton of fighters, directly and indirectly. Hard to think of all the loved ones he leaves behind. 💔 for everyone that was close to him, I’m so sorry.
