American marathon record holder and 2004 Olympic Bronze medalist Deena Kastor says this about Mahon:

I owe the longevity of my career to him being so knowledgeable and for reinventing training and therapy to keep me healthy. One of Terrence's greatest strengths is his insatiability to learn, not just about coaching, but life. He is full of so much knowledge and keeps reading great books and visiting with other brilliant people to continue growing.
