Who We Are

Nikki Dofflemyer

Nikki began her relationship with CrossFit like most people. After retiring from a 25-year career in law enforcement here in West Volusia, she needed a change. That change came when she walked into a CrossFit box in Pennsylvania. Athlete Nikki quickly became Coach Nikki. Passionate about movement at all ages and stages of life, Nikki has experience in everything from managing exercise for pregnant and postpartum athletes to helping clients maintain their quality of life. As head coach, Nikki is constantly learning and expanding the toolboxes of the coaching staff to serve Berzerk’s members better.

Stacey Dofflemyer

"I always wanted the energy to keep up with my kids and grandkids. I watched Nikki do CrossFit for years and thought I would try it myself. It's the best decision I've ever made for myself and my family."

Stacey is our resident guru for everything 'people' – from memberships to mindset. Mom to seven and grandmother to two, Stacey is no stranger to logistics or management. If this gym had a heart, she would be smack dab in the middle of it. Stacey combines professional skills from Volusia County Corrections and half a decade in gym operations with a passion for the fitness community.

Kara (Cummings) Guerrero

"We all have goals we want to accomplish in life. Moving our bodies and accomplishing goals in the gym primes us to take on challenges in our daily lives. My favorite part of coaching is helping others break through barriers."

Back in 2018, Kara walked into a CrossFit gym, fed up over having fallen off a monkey bar rig at a local obstacle course race. Three months later, she returned to conquer that obstacle. In that time, she fell in love with both the methodology and the community. From gymnastics and volleyball to triathlon today, she is a lifelong learner who loves helping athletes break through barriers.

Skeeter Little

"People make a gym. Gym people make a family. And family makes life great."

Skeeter holds a B.S. in Kinesiology & Exercise Science and has competed in collegiate basketball, obstacle races, and bodybuilding. In 2014, she found CrossFit and shortly after became a coach. When she's not flying planes (she earned her pilot's license!) or playing with her pup Goose, Skeeter programs and coaches specialty barbell classes.

Cordell LeMay

"Constantly varied high-intensity functional movements are key to physical independence. Do what you can, don't lift more than you safely can, and listen to your body."

Cordell began his CrossFit journey in 2015 wanting to reinvent his body and health. Having fallen in love with functional fitness, he is a dedicated advocate for proper form, joint mobility, and safe progression while challenging your personal limits.

Lauren Romano-LeMay

"Strength doesn't come from winning. Your struggles develop your strengths. When you go through hardships and decide not to surrender, that is strength."

When Lauren found CrossFit in 2016, she was looking for a mental and physical shift. CrossFit was that agent of change, helping her lose 50 lbs, build muscle, and unleash her inner competitor. She completed her Level 1 certification to inspire and guide athletes through their own transformations.

Shan Gao

"You get better and stronger by stepping out of your comfort zone. CrossFit will take you out of your comfort zone, and the coaches and community will bring you back."

Shan found CrossFit after growing tired of conventional gym routines. As an Emergency Room Physician and mom, navigating the high-intensity unknown is second nature. Inspired by Greg Glassman's analogy that 'doctors are lifeguards and CrossFit coaches are swim coaches,' Shan brings deep anatomical knowledge, injury prevention, and passion for lifelong health to every class.

Tammy Negri

Tammy serves as Chief Behavioral Officer for Strategies Inc. working with individuals with autism and intellectual disabilities. She has dedicated seven years to CrossFit alongside running numerous full marathons. Her favorite time to coach and train is the early morning (5:45 AM) and her favorite movements are double unders and overhead squats.

Meagan Burgess

A human resources professional who earned her CrossFit L1 in early 2024, Meagan brings a passion for helping people unlock their potential. She views CrossFit as a holistic lifestyle that balances demanding careers with peak physical wellness. When not in the gym, you'll find her on the water with her dog Maui.

Brittany Sande

"Every class I coach, my goal is to create an environment where you can escape reality and the stresses of the day, while accomplishing things you previously never imagined you could."

Brittany's fitness journey began with 15 years of competitive dance discipline. After co-owning a CrossFit gym for six years, she earned her Level 2 certification and joined CrossFit Berzerk. Outside the gym, she is a Director of Operations with a deep passion for military and veteran fitness.

DJ Wingate

DJ brings nearly two decades of athletic performance expertise. A former NCAA Division I cornerback for Marshall University and coach at USF and Davidson College, he has coached and analyzed film for CFL teams including the Toronto Argonauts and Edmonton Elks. DJ leads our youth development and personal training programs.

Noah Evans

An All-American swimmer and Florida high school state champion, Noah continued his athletic career swimming for the University of Alabama and earning gold and silver collegiate rowing medals. Noah translates elite aquatic conditioning and endurance into dynamic functional fitness coaching.

Delanie Turner

Delanie started CrossFit in high school alongside her mom. A school teacher by profession, she excels in class management, patience, and encouraging athletes of all ages. Delanie directs our Berzerk Buddies youth fitness program as well as adult group sessions.
