Mitch Kornberg

  • NSCA Certified Tactical and Conditioning Coach
  • NESTA Certified Personal Trainer
  • NESTA Certified Metabolic Conditioning Coach
  • Schwinn Certified Cycling Coach
  • FitPro Kickboxing Certified
  • TRX Suspension/Functional Trainer

I want to make personal training truly personal by listening and understanding my client's needs, likes and dislikes when it comes to fitness. I am also a Tactical Strength and Conditioning coach for first responders (military, fire/EMS, police corrections, etc.) and TRX Suspension Trainer certified, as well as a Metabolic Conditioning Coach. Being a retired police officer and over 50, I understand the hurdles of balancing family and career over time. Aging does not have to mean being out of shape and gaining fat. Together, we can slow and reverse the aging process - you can actually gain muscle and lose fat at any age.

Tristan Trotter

  • ACSM Certified Personal Trainer

I started my personal training career back in 2012, prior to that I earned my Bachelors of Science degree in Health and Human Performance from Austin Peay State University. Since then I've instructed an array of group fitness classes and developed personal exercise programs for populations who struggle with congestive heart failure, COPD, and even members with balance and coordination deficiencies. I have continued my education since then keeping up with the latest finds in exercise science but also remaining from one individual to the next. I pride myself in meeting you where you are in your journey and bringing your strengths to the surface. Wellness is a passion of mine and I am dedicated to making your goals a reality through thorough planning and implementation.
