What people are saying:

Rosenbaum for Council (10/2/19)

I am an enthusiastic supporter of Dave Rosenbaum for city council. I was looking for a candidate who is congenial, smart, positive and sincere, and whose background would add value to dedicated service. I’ve had the pleasure of getting to know Dave and I’ve found my candidate.

Many issues are pending before the council and these will be replaced by countless more. Therefore, I am most interested in what is important to a candidate and whether they have the ability to work effectively for those priorities as various issues come before the Council.

Dave’s priorities include preservation of parks, increased support for Town Center and small businesses, improved on-Island transportation, high-quality services including police, fire, water and sewer, and mitigating climate change. He realizes that resolution of the city’s financial issue is a fundamental concern, and he is ready to work with the community, council and city staff to find a solution. I agree with Dave’s priorities and believe that he can work in a collegial manner on the council to effectively advocate for his views.

Dave brings experience from a decade of work in the public sector for the federal government. As a Congressional staffer, he spearheaded a successful effort to save $2.1 billion and, at the same time, improve the experience of veterans appealing claims to the Veterans Affairs Department. Dave’s strength is to listen to constituents and to build consensus. This experience will be valuable as Islanders continue to identify what is important and determine how to ensure that what is valued is retained.

Dave’s belief that the real strength of the Island comes from the wonderful people who make up our community perfectly expresses who he is. He trusts that we can work together to ensure that we continue to enjoy a high quality of life and respond to challenges that will come. He is ready to lead. I encourage you to join me in voting for Dave Rosenbaum.

Rosenbaum support (Mercer Island Reporter - 10/9/19

As a former city councilmember, I would like to ask you to join me in supporting Dave Rosenbaum for Mercer Island City Council Position 1.

Dave’s family has been on Mercer Island for three generations, giving him strong roots in our community. He values our parks, our partnerships with the schools and our history.

His background as a policy adviser in Washington, D.C., gives him proven experience. He has skills in collaboration and decision making that lead to sound decisions. We need this as we move forward. Someone who knows us, works for us and can bring us together.

I support Dave Rosenbaum because he brings a background in issues a city council deals with all the time: Budgeting, public works, public safety, and transportation.

I support Dave Rosenbaum because he understands the unique character we have here in our community and will stand up for us regionally, locally and with all people.

Our community needs someone with these roots, these skills and the understanding that we are stronger together.

We need Dave Rosenbaum leading us into the future.

Rosenbaum knows what matters most (Mercer Island Reporter 10/16/19)

Dear Editor,

As Mercer Island residents for the past 31 years, we would like to encourage you to support Dave Rosenbaum for city council Position 1. After raising our daughters here, we are now fortunate to be watching our grandchildren grow up on the island. We love living here and know that Dave understands, and will enhance, what matters most to Islanders.

We have known Dave’s family for 45 years and know that he has inherited their kindness, focus on service, and dedication to bettering our community. He is thoughtful, detail oriented, and focused on delivering results. He has the vision to lead our community into the future, as well as the ability to listen to the perspective of all Islanders as challenging decisions are made. Above all, he has a strong moral compass that will guide his decision making.

As ballots arrive this week, we encourage you to make the best choice for the long term success of our community and vote Dave Rosenbaum for Mercer Island City Council Position 1.

Vote for Rosenbaum (Posted on Mercer Island Reporter 10/21/19)

I am enthusiastically supporting Dave Rosenbaum for Mercer Island City Council. He has a positive vision for our Island that benefits our diverse community; families with children in the schools, retirees, and active town center residents. Returning to Mercer Island to raise his family is an indication of his commitment to this special place. I think he has the foresight to enhance the unique nature of our community as we prepare to meet the needs and opportunities of the future.

Having worked closely with Mercer Island small businesses for almost 30 years, I know how important it is to have members of the City Council focused on economic development and helping those businesses thrive. Dave spent more than a decade in Congress working on issues such as those facing our local businesses and will use that experience to support and grow the Island business community

His experience and deep roots in the community have prepared him well to serve on the council, and I know he will be an effective leader. I encourage you to vote Dave Rosenbaum for Mercer Island City Council Position 1.

    Dave and I met for the first time last Friday 9/6, after which I knew that he will make an exceptional member of the Mercer Island City Council. He is smart, experienced, and thoughtful. He will listen to all sides of an issue and carefully consider all of the pros, cons, risks, and rewards before making a sound decision. Dave will work very well with fellow council members as well as the city staff and our regional partners, and he will do so without losing sight of what really matters: taking care of our great community.
