Her family goes to New York City every summer with Spreadtruth Ministries to run inner city soccer and basketball camps, VBS as well as set up prayer stations in the streets and parks.

After having children, Susan had taken a break from exercising and eating unhealthy and had gained quite a bit of weight. In the fall of 2010, she made a decision to take back her life and started attending boot camp style classes and eating a balanced diet. Within 2 years, she lost nearly 80 pounds and 8 sizes and has kept it off. Her journey to get stronger and leaner is still going. She learned to love exercising again and turned that passion into a career to help others do the same.

She began taking one on one and small group clients while getting better at what she did. She always loved how boot camp had changed her life and she had a passion to help others do the same thing. When God opened the door to become a part of the Powerfit Instructors Team, she jumped on it.

As a Powerfit Trainer, she understands the struggles that some face when starting a new exercise program, because she has been there. She loves designing quality workouts which will not only challenge the beginner but the seasoned veteran as well. Susan strongly believes that by maintaining a positive, encouraging, and motivating environment at all times, anyone, at any level can reach their goals.
