I believe in strength from within, and fitness as a lifestyle. It is my mission to teach my clients that they are stronger than they think, capable of more than they knew possible. I believe in leading by example, and am constantly looking for ways to better myself, because if I can inspire just one person or help a person change his or her life for the better, then I am on the right track.

To me, fitness goes beyond just weight-loss or maintenance. It connects the body, mind, and spirit and becomes a tool - a key to unlocking a potential and inner strength you may not have realized you possess. It is my goal to help others in this process of self-discovery so that they may find their 'light' and shine brightly!

I've been working in the fitness industry for 15+ years and have been at the Warrington location since 2005, prior to Cornerstone's ownership. I have seen fitness trends come and go but one thing never changes- once you engage in a healthy, active lifestyle it is more about weight loss or looking good. It is about feeling good, both mentally and physically. Don't underestimate yourself, have confidence in your capabilities. You are stronger than you believe, and you'll never know whether you can do something unless you try.

Your personal fitness routine plays a MAJOR role in performing your absolute BEST! I believe that adapting a healthy lifestyle, with attainable, realistic goals, can be a life changing experience. Remember, your physical energy is one of the most precious resources you have and training and conditioning play a pivotal role in your overall health, happiness, and success. Proper form, functionality, core strength and moving well are all KEY to one very important goal, to reduce the risk of injury. Through my own personal experience as a collegiate athlete, mother to triplets, and having undergone a hip replacement, I offer a wide range of knowledge in the fitness realm to make sure you attain your goals, one step at a time!

I strive for balance in my life. That's why my kickbox class is a balance of serious training (martial arts principals, kicking form, boxing techniques) AND fun fitness with laughter. You learn real skills while getting an intense workout (that can be modified if needed!) All fitness levels welcome. All I ask is that you come to my class with a positive spirit, ready to give 100% effort, because that's what I give of my energy to each class.
