Coach Greg Jones has been more than 25 years in the making! I’ve been a certified personal trainer and training people since playing College Football in the mid-nineties. My area of study in College was Physical Education, where I received my Bachelor’s degree, along with a minor in Nutritional Health from Eastern Oregon University. I’m classically trained to teach Phys Ed to youth and adults, along with being a multi-sport collegiate athlete, who knows the struggles of injuries and adversity with a plethora of experience make me better suited to be your strength, conditioning, contest prep, or just general fitness specialist.

DaMarr Easton

Group Trainer
My name is DaMarr Easton. I have been a Certified Trainer and coach for more than 20 years. Born and raised in the Pacific Northwest, I am a former High School and college athlete. Having a love for fitness and sports performance is a great understatement for me. I am a sports enthusiast.

Having been in the best shape and the worst shape of my life, I understand the importance of having a solid foundation to work from. Being that guide or helper of many to reach and become the best versions of themselves has been my greatest desire.

Creating a fun and challenging atmosphere, welcoming all that come into Monkey Bar to experience the passion for life and well being. That’s my mission…..
