Dennis Sims
Dennis began following CrossFit in the summer of 2007 thanks to a fellow SWAT team member who found this curious new way of training. After reading material on the CrossFit.com website, subscribing to the CrossFit Journal, and watching many of the demo videos, he transitioned over to the CrossFit style of fitness training and continues to implement it as his training regime to this day.
Dennis was a scholarship college football player who became a police officer eventually instructing and certifying other officers in the area of physical fitness. Dennis joined Off the Grid as a member several years ago after performing CrossFit workouts in traditional gym settings. Dennis wanted to continue to grow as an athlete and instructor and became a member of the Off the Grid coaching staff. Dennis has a M.A. (Criminal Justice) and M.P.A. (Public Administration) from Rutgers University, a B.A. (Law and Justice) from Rowan University, and is a certified New Jersey Police Training Commission Instructor with an added specialization as a physical fitness instructor. Dennis remains on staff at the Gloucester Count Police Academy as he looks to assist others, inside and outside of CrossFit, to lead an active lifestyle. Dennis enjoys welcoming new members to Off the Grid as he works hard to ease apprehension about this new method of training.
Dennis is also married with two beautiful daughters.

Jen Mcmullen
At the age of 40, after living a mostly sedentary lifestyle, Jen decided that if nothing changes, nothing changes; so she started walking every day. This led to a little running, and then a lot of running. After three years of nothing but running, she’d developed many new issues/injuries with tendons and ligaments. For a change, she thought she’d try obstacle course racing, but she needed to gain strength. In 2012, after driving by many times, Jen finally stopped into CrossFit Off the Grid to see what “CrossFit” was all about.
She signed up and fell in love with it! Jen helps introduce new members to the world of CrossFit by guiding them through our Intro and Foundation On-Ramp classes.

Kelly Wittenberger
Kelly was first introduced to Crossfit in 2013. She was intrigued at how it combined her love of gymnastics and kettlebells with unfamiliar barbell movements. After years of running alone for exercise, the camaraderie of the Crossfit community, in addition to the varied, challenging workouts, is what helped her get hooked from the start. Kelly graduated with Bachelor degrees in Elementary Education and Psychology from The College of New Jersey and has received her M.A. in Special Education in May 2019.
She is an upper elementary special education teacher. Previously, Kelly was a full-time personal trainer and small group exercise instructor.

Kat Norcutt
Hi there, my name is Kat and I have been involved with CrossFit for 4 ½ years! My passion for CrossFit developed quickly as I started seeing results immediately. I am a mom to six children, and as a busy mom, I have developed some unhealthy habits over the years. As the kids started leaving the house and those responsibilities that were holding me back from leading a healthier lifestyle were disappearing, I decided I needed a change.
I guess you could say I went through an empty nest syndrome and realized that my life didn’t revolve around my children and their many activities anymore, so I decided to take my own health and well-being into my own hands. Now that I have been doing this for a few years, I decided to pursue CrossFit to the next level and help those who are starting out. I began to educate myself within the health and fitness industry and look forward to whatever the future may bring with it! I have always felt that the more knowledge you have in a specific subject, the better you are equipped to handle any situation that may arise. So when the opportunity presented itself, I decided to come on board CrossFit off the Grid. I did so because I love helping people, and I love showing others what this community can do for them. I have years of customer service experience, and pride myself in relating to all walks of life!

Leanne Kuhn
Hi everyone! My name is Leanne, and I am super excited to join the CrossFit OTG community. I am married to my husband, Bruce, and we have a daughter, Ella. In addition, we have three fur babies- two dogs and a cat.
I graduated from Rowan University in 2015 with a BA in Elementary Education and from Wilmington University in 2021 with an MA in School Counseling. My favorite things to do are hiking, OCRs, going to concerts, and going to the beach.
When I was in college, I stopped playing sports and was bored working out at the gym alone. I contemplated joining a CrossFit gym for years. I finally started CrossFit in 2017 and never looked back. I attended the CrossFit Level 1 course for the first time in 2018 and started coaching at the local gym I was a member of.
Since then, I have also completed my Precision Nutrition L1 certification. I am currently in the process of completing my GGS Women’s Coaching Specialist Certification and GGS Pre/Postnatal Coaching Certification.

Kelly Amato
Kelly entered the Crossfit world after years of trying on the various options for fitness out there.
Her passion for exercise came after the sudden loss of her mother at a young age. At-home workouts led to community group runs and a multitude of different fitness arenas; ultimately landing her at Off the Grid.
Kelly is a Licensed Clinical Social Worker with 15 years of experience as a Mental Health Therapist with a concentration in nutrition and mind/body wellness. She has seen first hand the impact nutrition and fitness has on mental health and hopes to bring that to her coaching at Off the Grid. She is continually motivated by seeing others progress both in and out of the gym.
She loves that she gets to share this community with her fifteen year old daughter Caelyn, setting her up for a life of longevity and health.

Greg Martin
Greg started CrossFit in 2013 as a 42 year old, unhealthy and sedentary man. Fearing that his lifestyle was going to shorten his life, he decided to make a change… for himself, for his wife and for his kids! Greg, a weightlifter in high school and in college, had not worked out in many years, until he found CrossFit Off the Grid. After losing well over 100lbs, Greg turned his unhealthy, sedentary lifestyle into a much healthier, active and happier lifestyle.
Greg has gone on to compete in the Escape the Cape Triathlon, the MS City to Shore 100 mile cycling event as well as Tough Mudder, Rugged Maniac and many other running races and obstacle events, many of which raised money for charities such as Children’s Hospital of Philadelphia. Greg’s motto is “If I can, you can!” and does all he can to motivate others to give CrossFit a try! In 2017, Greg completed his CrossFit Level 1 Certification with the goal of helping others who simply feel like they CAN’T… and showing them they ABSOLUTELY can… and have fun doing it! Greg is married to Tracy, a member of OTG, one who swore she never “could”… and now DOES!
Greg is also a father of three daughters who are the apple of his eye. Greg is a Director of Operations for a restaurant company and an assistant football coach for Washington Township Parks and Recreation. Greg coaches Introductory classes, Foundations Sessions, Fit Camp and the Youth Strength and Conditioning classes here at Off the Grid.
