I was lucky enough to have an initial consultation with Isaac from Fit for Life today. Am so pleased with his empathetic and engaging style. He has shown me that he is knowledgeable as to the subject matters we discussed and is enthusiastic to get my nutrition & exercise program into high gear. Glad I found him!
