Neon Luong
- BS Kinesiology
- Certified personal trainer
- Bodybuilding and hypertrophy specialization
As a first-generation immigrant, Neon struggled to find his identity in his early 20s. Fitness and physical activities provide a haven for him to express himself. Dabbling into calisthenics, bodybuilding, weightlifting, and powerlifting, Neon realized the positive impact of physical movements on the human body. His first client was actually his mother, who was undergoing menopause in her 60s. Helping his mom regain fitness and independence, he discovered he can meddle his passion for fitness and helping others. After his realization, he decided to major in Kinesiology. Going through his personal training journey in various settings such as commercial gyms, private corporate fitness centers, in-home training, etc., he has acquired much experience in empowering others through fitness. Priding himself on being evidence-based, he specializes in helping clients with both body recomposition goals (muscle gain, fat loss) and performance-oriented goals (faster, bigger, more powerful).
Jeff Venditte
- Certified Personal Trainer
- Certified CPR/AED
- MBA (Texas A&M)
Throughout my life, I have participated in a range of sports and physical activities. Upon beginning my professional career in engineering and sales, I encountered significant workplace pressures and found it increasingly difficult to allocate time for both family and personal wellness. Years of inconsistent exercise and suboptimal dietary choices eventually led to health concerns that necessitated a shift in my lifestyle. This realization prompted my retirement and a renewed commitment to regular exercise; however, sustaining consistency initially remained a challenge.
At my wife's suggestion, we enrolled in a 12-week transformative program at GAF. The measurable improvements and genuine enjoyment from this experience encouraged us to continue beyond the initial session. During this period, I discovered a passion for supporting others on their own paths to wellness. As a result, I pursued further training in fitness and achieved certification as a NASM Certified Personal Trainer (CPT).
I am dedicated to assisting individuals who aim to enhance muscle mass, strength, balance, and overall well-being. Outside the gym, I remain current with advancements in fitness research, actively participate in our daughters’ lives, and enjoy activities such as golfing, camping, hiking, walking our dogs, and maintaining our yard (not really much fun, but good exercise).
