David DeMesquita

Founder and CEO

David DeMesquita is a functional health coach on a mission to “make lives better”. Many know of him on Instagram as “Dynamite D” for his honest, down to earth word posts about bodybuilding, health and business. For 10 years, he has helped people from a wide range of backgrounds to not just optimize internal systems, but ALSO achieve their best physiques ever.

He has worked with some of the top Olympians in the IFBB and continues to help athletes of all ages and experiences. His passion for hormones, autoimmune and digestive issues stemmed from family and close friends he witnessed struggling. David officially founded his coaching company, DeMesquita Nutrition, in 2021 after leaving a corporate IT position and building his knowledge from medical doctors and world-renowned practitioners. He works with his team of coaches to further expand his reach to help others with their health and fitness journeys.

David has over 11 years of his own competitive bodybuilding experience, being coached directly by some of the best in the industry including the late Matt Porter and John Meadows, and Austin Stout. His love for the sport continues, as he continues sharing content on his YouTube channel with show predictions and division analysis. Outside of fitness, David is a nerd, and enjoys playing various PC video games and watching anime. He enjoys weekend house projects and playing with his Bengal cats, Luke and Leia. He reside in Atlanta, Georgia with his wife Caroline and daughter Aleta.

Caroline, COO and Boss Mama, Caroline believes fitness starts within. She first got her start as a natural athlete in figure, and learned hormone balance with her own challenges with adrenals, gut health and hormone dysfunction. She works with women to improve their self worth and mindset, all transforming their physiques and hormones. She describes herself as a “recovering perfectionist” and has found more feminine balance through motherhood. 

Kyle Gabriel began his coaching career in 2019 during his pursuit as a classic bodybuilder! As a coach, he constantly strives to better himself. He has pursued additional education from mentorship by some bright minds in the industry including Austin Stout , Matt Burzacott and Zach Etheridge. He is a critical thinker who thrives on the challenges of gut and hormone cases. Overall Kyle enjoys helping people reach their goals whether that be winning shows or just feeling better daily and improving overall wellbeing. "Everyone says you have to do what makes you happy and coaching is exactly that for me," says Kyle. Kyle resides in Martinsburg, West Virginia with his wife Brett, celebrating over 10 years together! Kyle's favorite cheat meal would be a toss up between five guys burger and fries or some sushi rolls!

During the majority of Zach Etheridge's adolescence, he was overweight and lacked confidence in himself. Through his own transformative journey, Zach grew a passion for helping people become the best version of themselves. Zach has been coaching lifestyle and bodybuilding clients since 2016. In this year, he also became a firefighter. Since that time his experience has only concreted his beliefs in leading a team by example. He feels that being physically fit and healthy is not only important to himself and his family, but also the citizens he serves and the clients he pours himself into. Zach resides in Social Circle, Georgia with his wife Lindsey and their dog Coco.

Ethan Kinard is a coach with Aegis Nutrition and a full-time firefighter based in Philadelphia, Mississippi. Known for his strong work ethic and disciplined lifestyle, Ethan brings the same dedication from the fire service into helping his clients build stronger physiques and healthier habits.

Ethan has completed the J3U Level 1 Certification, the Dom Kuza Bloodwork & Prep Course, and has also developed his coaching knowledge through mentorship with respected coaches Chase Watford and David Mequita, expanding his understanding of physique development, health, and contest preparation.

Outside of coaching, Ethan is married to his wife Claire, who is also a bikini athlete, and together they share a passion for the fitness and bodybuilding lifestyle.

Ethan truly enjoys helping people become the best version of themselves—physically and mentally—through structured training, nutrition, and accountability.

When it comes to favorite foods, he keeps it simple with a staple he loves: Quaker Oats with peanut butter and cinnamon. 

As someone with many interests, she developed a deep passion for bodybuilding. She has been competing for the past four years, beginning in the bikini division and recently transitioning to the fit model division. She earned her pro card in July 2025. Her journey into fitness was deeply personal, using health, training, and discipline as tools to rebuild her life through challenging seasons. That foundation now fuels her passion for helping others become the best version of themselves from the inside out. She has been coaching clients since 2023, and her philosophy is that this is more than coaching, it’s about connection, growth, and becoming.
