About the Trainers

 Jim Denofa: Owner/Trainer


  • -BS health and physical education
  • CrossFit level 1 trainer
  • USA Weighlifting level 1 sports performance coach
  • ISSA certified personal trainer

 Training Background: 

  • Strength and conditioning for 20+ years
  • CrossFit since 2006

I began weight training when I was 13 years old. I began with the typical bodybuilding routine, but soon discovered powerlifting. After years of squats, deadlifts and bench presses, I began to want more out of my training. I then decided to learn the Olympic lifts, this got the wheels turning for me and I tried some strongman training soon after. I found myself struggling to find a balance in my interests in strength athletics. In 2006 a friend introduced me to CrossFit. WOW! I had finally found a program that I could combine all of my goals and interests into. The diversity of the CrossFit program has given me incredible results, both as a trainer and an athlete.

Coaching Background:
  • Personal/ Group Training for 10+ years
  • CrossFit Trainer since 2008

I have been a certified trainer since 2003. Training one on one with clients and also teaching gym classes to children. In 2005 I began coaching the strength and conditioning programs for the men’s and women’s golf teams at Cameron University. Soon after I began coaching the volleyball and basketball teams strength programs as well. In early 2008 I received my CrossFit level 1 certificate and began teaching the CrossFit method soon thereafter.

  • CrossFit Level 1 Trainer
Training Background:
  • CrossFit since 2010
 I was never the sports girl growing up. I tried Soft Ball and Volleyball but nothing seemed to stick. My husband Jim tried to get me to work out with him for 8 years. I couldn’t be convinced that working out needed to be a part of my life. Then one day in 2010 I decided to try CrossFit. Guess what? It had to be my decision. That is what it takes. You have to decide to make the change for yourself, no one else can make it for you. I was soon hooked on the new challenge I had given myself. Now I am in better shape then ever in my life and continue to seek new challenges in the gym. Striving to become a better CrossFit athlete helps keep me motivated and continue to love training.
Coaching Background:
  • CrossFit Trainer since 2012
My husband Jim was my biggest inspiration for becoming a coach. Watching him train people to reach goals that they never thought they could achieve was fulfilling even though I was not doing the coaching. I constantly listened to Jim train and coach and soon felt that coaching was turning into a passion of mine too. In 2012 I got my CrossFit Level 1 Certificate and started coaching at our gym. Nothing is better then helping someone beat a personal record or learn to do something they never thought they could do.

“Shut up Jim!!” – Dustin AKA Mac


  • CrossFit Level 1 Trainer

Training Background:

  • CrossFit since 2013

I’ve been playing sports since I was 4 years old; whether it was at the peewee, high school, intramural, or college level. I was always one of those “power lifters” / Monday – chest and triceps, Tuesday – back and biceps, ect. I saw results and gained mediocre strength but it was a slow methodical gain with periods of plateau that caused me to lose motivation or take an extended break. I was not and am not a runner so my cardio has never been that strong. I began my career in law enforcement in 2009 and began to lose the time and motivation due to the schedule forcing me to work odd hours and my overall lack of energy. I became stuck in a rut until one day I was training at work with a coworker and he invited me to workout with some other employees. We began doing this workout with box jumps, Turkish getups, pushups, dips, and other non-familiar difficult things. When I asked what this was called I was told “CrossFit.” I had heard of CrossFit but only the typical negative hater comments from other “power lifters.” I continued training with my coworkers for a few weeks in the afternoon until one day I came and they weren’t there. I saw them later and they told me they started training at a CrossFit gym called Havoc close by. I got the invite and began training there. There was a lot of strength training right off the bat so I was hooked on that but I struggled with flexibility/mobility. I’m a very competitive person so what I lacked in the cardio areas I made up for in certain strength areas. Before I knew it I was gaining ground on the cardio people and still excelling in the strength areas. Don’t get me wrong I struggled and still struggle in plenty of the strength and cardio areas. I have come a long way in flexibility/mobility but I continued to struggle everyday with them and several other skills/modalities. What I slowly began to realize is that I made more progress in my overall fitness, strength, performance, motivation, and quality of life in the year and a half that I was doing CrossFit than the fifteen years I was “power lifting.” I couldn’t say a particular day, week, or month when it happened but I can say for sure that I am addicted to CrossFit. I’m currently feeding my addiction at CrossFit Havoc Monday through Sunday and have no plans of slowing down.

Coaching Background:

  • CrossFit Trainer since 2014

Whether it was though his teaching, working out with us as a group, his terrible music choices, terrible jokes, terrible dancing, and big heart Jim has been motivating me ever since I began working out at CrossFit Havoc. I slowly began helping him give coaching ques to my friends who were training in the classes with me. Both Jim and Natasha approached me and told me I’d make a good coach. Over time I saw I was helping my friends make progress and realized I might enjoy this more than just a little. In 2014 I took the level one certification down in Miami, FL and began interning as soon as I could. I gained a lot of coaching techniques, verbage, and time management from both Jim and Natasha. I began training on my own after a couple months and the feeling is pretty awesome. To help someone who I struggling with a skill or movement improve is an amazing feeling that I relish. I am looking forward to teaching more and more as soon as time becomes available.

Tracy Rankin: Trainer


  • CrossFit Level 1 Trainer

Training/Coaching Background:

  • Gymnastics and Competitive Pole Vault
  • CrossFit since 2012
  • College Strength and Conditioning Coach
  • CrossFit Trainer since 2012
 I have been an athlete my whole life, participating in a variety of individual and team sports ranging from Gymnastics to Pole Vault. From 1999 through 2010 and I competitively pole vaulted and trained with Olympic Pole Vault coach Rick Suhr and Gold Medalist Jenn Suhr leading me to compete at the collegiate level.  After receiving All American Honors for Pole Vault and a B.S. degree in Broadcasting I began coaching Track and Field as well as Strength and Conditioning at the University of Rochester in 2008.  A few years later I enlisted in the United States Coast Guard, which brought me to Staten Island. Although my past coaching and teaching fulfilled the desire to keep sports and education in my life, it wasn’t until I discovered CrossFit in January 2012 that I was re-inspired as an athlete and shortly after as a coach. My passion to compete both with and against others has been rejuvenated within the CrossFit Community.  I love the competitive atmosphere that CrossFit provides and look forward to pushing athletes to reach their personal goals as well as being pushed by others to reach my own. In May of 2013 after attending Officer Candidate School for the Coast Guard I was stationed in Boston. I quickly found my place in the CrossFit Southie community where I became part of their coaching staff training over 700 members. Along with being part of the staff I was also invited to be part of the Crossfit Southie’s Regional team competing at the 2014 Northeast Crossfit Regional’s. After getting married in September 2014, I relocated to Portsmouth, NH with my new family and joined Crossfit Portsmouth’s community as an athlete and coach. In June 2015, following my separation from Active Duty, my family and I moved to Parrish, FL after my husband received military orders. I quickly found the Crossfit Havoc community and knew it was the right fit. I am very excited to share my knowledge with the athletes here at Crossfit Havoc and look forward to learning from every member as well.

Alicia Brogan: Trainer



  • CrossFit Level 1 Trainer

I’ve always been an active person, no so much an athletic one, though. I’ve worked out, on and off, since my freshman year of high school. I’ve done it all; the typical and traditional all cardio regimen, light weights and cardio mix, overloading on carbs (the wrong ones) before running, and unfortunately, but of course, the 3-a day gym rat while experimenting with little to no food, regimen. I always had it in my head that heavyweights and mixed up workouts would give me a manly physique. I’m sorry it took me so long to figure out this was the exact opposite.In 2006, I became constantly sick and I ended up having my gallbladder removed in 2007. Afterwards, my diet no longer consisted of red meats and fried/greasy foods. In my head, I thought, I’m eating healthy and can eat whatever I want as long as my stomach tolerates it. This went on for 3 years. I slowly started working out and started seeing results, just not impressive ones. I was “skinny-fat” and was fine with it… at that moment.

In 2011, I started dating my fiancé. We did what most couples do in new relationships; get comfortable, get lazy, gain weight, start an unhealthy trend, but we were happy! In 2012, our son graced us with his presence. My fiancé and I were rocking the “mom and dad bods” without even realizing it. Everything in our lives was going great, until I realized how unhappy I was. I no longer had the cute little body I had known my whole life, it was replaced with extra, extras everywhere! I no longer felt comfortable in my own skin and was starting to lose vision of the person I was. We decided to make a change, join a gym, and work hard. We motivated each other and worked out together 4-5 times a week. After about 3 months, we both noticed absolutely no change in our bodies and I was getting frustrated quickly. I felt hopeless.

In April of 2014, a couple of good friends of ours opened a CrossFit gym in Tampa. I had only heard the typical bad CrossFit banter and had no honest inkling of what it really consisted of. We decided not to hate something we’ve never tried and in effort to support our friends’ new adventure we dropped in to try it out. The workout was horrible! I pushed me way past any limits I had ever known before. Afterwards, I fell on the ground, searching for a breeze and air, and while having what can only be described as an outer body experience, I realized I was already wanting more! As horrible as I felt, I also felt proud and accomplished for not quitting! I quickly became a permanent fixture in the gym. I was hooked!

In 2015, we relocated to Sarasota. We were so sad to leave our gym and thought for sure we would never find another. When researching local CrossFit gyms; it was overwhelming because there were so many options. The first gym we dropped into was CrossFit Havoc. I was excited and nervous, because well, have you seen our daily WODs?! At the end of our first workout at CFH, we realized that not only had we lived, we had found our new home gym! It was such an awesome feeling!

Our family has been members at CFH for over a year and rarely miss a workout. The amount of progress we’ve made is incredible! I am the happiest and healthiest I have ever been in my life. I have come to realize that I have a true passion/obsession for not only improving myself but helping to motivate and improve other people, as well. When Jim and Natasha approached me about becoming a CF trainer, I was floored! I couldn’t believe that they believed and saw that much potential in me. I am so eager to motivate others. I am so excited to see where training takes me in the future. I know now that this is my calling and can’t wait to help others bring out the best in themselves.

  1. Coach,
    I was doing a pretty painful “fran” the other and I’ll be darned if I wasn’t doing some pretty good thrusters. Later that week I completed a respectful (650) “Crossfit total”. Your squat coaching really did the trick with me and my flexibility continues to improve! Still working the overhead squat issue but making progress. At least one other guy in the group is using your Dynamic Movements. Our little prison gym here in Iraq continues to improve a little at a time, I think we got a line on a tire and I have a duffle ready for “labor”. This is gonna suck!
    Thanks for everything!
    My best to you and your family and especially Victor aka Mini Coach!


  2. Glad I found Crossfit Havoc! This is just what my body and mind needs. Two sessions under my belt, and I can’t wait to do it again! Thank you Jim for bringing your passion, talent and service to Lawton.

  3. I am so glad I found Crossfit Havoc! Jim and Natasha are awesome. Both of them are extremely knowledgeable and passionate. They welcomed me with open arms and have been a constant source of inspiration and knowledge.
