Prior to moving to Florida, Cathy was very active in the Portage Michigan Board of Education, spearheading the Great Books program in the elementary schools there. Currently she is on the steering committee to bring a much needed Boys & Girls Club to South Lake County. Cathy and her husband Mark live in Clermont and have three children.
