Tom was elected to serve on the London Grove Board of Supervisors in 2001 and became chair in 2004. As chair, Tom has lowered property taxes by nearly 9%, preserved farmland, and passed an ordinance to obtain impact fees from developers to fund parkland. He also allowed for the expansion of Yeatman's Mother Earth Organic Mushrooms and Gourmet's Delight, a group that instituted industry best practices and eliminated harmful air byproducts. In 2006, Tom ran against the incumbent, now retiring, and received 47% of the vote. That year, Tom raised $200,000 for the race, which was more than any Democrat had ever raised in the district.
