  • Jessica Patterson Level-1 Certified Trainer

    Jessica decided to come try CrossFit on Memorial day 2013. Murph was her very first workout and she was hooked. She came in the next day and signed up! A little over a year later Jessica decided to get her Level 1 Certification because she wanted to learn more about CrossFit and become a better athlete and to have the ability to coach if the opportunity came about. Now she has been coaching for about 7 months and LOVES it! She feels blessed to have the opportunity to help people live healthy lives through fitness. Jessica truly feels there is nothing better than the smile on her clients faces when they get their first double under, or first kipping pull up, or when they PR on their clean and jerk! CrossFit has changed her life in so many ways and she hopes the same for everyone who comes into CFM!

  • Bobby Wood  Level-1 Certified Trainer

    Bobby has always been active, playing sports since childhood. He got his first start in weightlifting while playing football in high school. In January of 2013, Bobby reluctantly tried CrossFit after some convincing from a friend. He was immediately hooked due to the challenge, variety of work outs, and the community atmosphere. Bobby became highly motivated to improve as an athlete. As he pursued further knowledge, he found that he enjoyed sharing what he learned with his fellow athletes, so he earned my Level 1 certification in June of 2014.

    Bobby’s personality type is to pay close attention to details. His philosophy on coaching is to help the athlete break down movements into smaller components, improve each piece, and then put it all back together for a more efficient performance.

    The biggest reward for him as a coach is taking the athlete through that process and sharing their excitement when something “clicks”.


    Marcy is proud to say she is married to the most perfect person. They have 3 dogs and a Koi pond with 11 fish. As a Massage Therapist for over 25 years and a woman in her 50’s, Marcy understands the importance of staying strong and fit. She is very grateful to have been a part-time Coach for CFM for almost two years now and Coaching others to be stronger physically and mentally enriches her life in so many ways. Our members, owners, and coaches feel much like family to her and she feels truly blessed.
