    She has developed a well-rounded health and fitness philosophy over her career as a trainer. Tish admits that she spent much of her 20’s and 30’s “killing it” as an instructor and triathlete and then realized her body was trying to send her signals. She discovered that her balance was gone. She had over trained and ignored so many other aspects of her wellness that she had to take a huge step back. From that point on she focused on creating a more complete wellness approach that will take her well into her 80’s. Tish hopes to help others, even the most extreme athletes, understand the importance of “balance” and how we can still achieve our goals while taking time to focus on the importance of a balanced life and healthy body.
