BIO: My inspiration for how I train my clients and athletes revolves around a combination of prehab, functional strength training, and rehab work. Working my way up to become a Division II Volleyball player, I learned the value of mastering one level of fitness at a time. Learn to control your own bodyweight before you lift heavy, gain strength and learn how to control weight before you work on power - and the whole time stay focused on performing the smaller exercises to reduce chance of injury and strengthen problem areas you already have. If you train like an athlete, moving through all planes of motion focusing on strength and power, you will be ready for anything life throws at you and stronger because of it.

Personal & Performance Training Consultant

Bachelor of Science in Community Health Education from the University of Indianapolis
Certified Personal Training certification from the American College of Sports Medicine
Experience: I have been working in the fitness industry for six years (since August 2013). 

BIO: My entire life, I've been passionate about exercise and staying physically active. The physical, emotional and mental benefits I've seen through exercise have been truly life changing and I've had the privilege of witnessing my clients experience the same. I am a determined person who is passionate about helping others. I'm grateful to have found a way to live out my passion and share the gift of fitness with others.

In the past, I have taught exercise boot camps, TRX, boxing, individual personal training, etc.  I have a very diverse clientele, both in terms of age and general fitness level/ability and am experienced at modifying workouts to help meet client’s individual needs and personal goals, whether that’s losing weight, gaining muscle, increasing strength or just having fun. My niche is clients with injuries and chronic issues as I enjoy teaching people how to move with proper form, correct body alignment and prescribing corrective exercises. I strive to provide fun, challenging, and customized workouts while providing a positive, encouraging environment in which all clients can achieve their maximum potential.  

If I'm not strength training or boxing in the gym, you can find me out and about appreciating art and all the little things in life!

My motto: Give your best. Be your best!

I would love to have the opportunity to work with you individually or as a group.
