Gail Lewin  •  Executive Committee Member Political Chair

I have been a Sierra Club member since 2003. I have served several terms on the Executive Committee and as the Chair of the Miami Group Sierra Club Political Committee. That Committee has endorsed numerous candidates for local, state and federal elections. It is important to let our members know which candidates support environmentally friendly policies, laws and regulations. In 2018 we were very active in the Cincinnati and Dayton geographical areas. At ExCom I have served as the ExCom liaison to the Political Committee and I have performed various functions in support of the Group's Treasurer. Having a sound financial condition helps the Group succeed in all of its sponsored activities such as Outings, Memorial Trees, workshops, the monthly Innings, our Annual retreat, and more.

Trish Brechlin  •  Executive Committee Member Dayton

I am ready to pursue what the Sierra Club members in southwest Ohio think are most important to fulfill it's mission. I am a resident of Dayton and therefore am most interested in pursuing environmental issues and advocacy in the greater Miami Valley. I have interviewed local and state-wide candidates for the 2018 election, co-lead Dayton Committee meetings, attend local outdoor events to promote Sierra Club membership, and co-lead clean-up event with Wright State Outdoor Resource Center at Eastwood Lake.

With over 20 years of environmental experience, I am well prepared to serve the organization. I have worked in the federal government both as a regulator and the regulated. Thus, I have a unique viewpoint of seeing both sides to an environmental problem, having worked with state and local governments and citizen organizations.

More specifically, I gathered and reviewed documents for the Sierra Club for the Metropolitan Sewer District consent decree in Hamilton County.

Other endeavors include serving as a co-director for natural resources with the League of Women Voters in Dayton and sampling and summarizing water quality data for a volunteer stream team.
