    I began working with Susan almost a year ago. After two knee surgeries I was struggling with simply walking. I had tried several different "personal trainers". They were unable to modify exercises that I simply could not do. Susan helped me to find exercises that I was able to do. I am so much stronger now and have progressed to where I can walk for miles/hours again. She truly does personal training--not one on one training for everyone. Her knowledge of the muscles also helped me to understand how my body needed to heal. She is wonderful!
