SWAMPSCOTT – Town residents should prepare themselves for knocks on their door with four candidates vying for two open seats on the Board of Selectmen.The two open seats will be vacated by Chairman Rich Malagrifa and Vice Chair David Van Dam, who opted not to run again. As of Tuesday?s deadline for nomination papers, the four candidates on the ballot for April 30?s election are Patryk Januszewski, John Callahan, Charles Patsios and Matthew Strauss.Strauss, 53, plans to bring “experience, leadership and vision” to the board as a returning selectman. Strauss served one term on the board as chairman before losing to Glenn Kessler in the last election. “With me, there will be no learning curve,” said Strauss. “I understand process, budget process. There?s no question in my mind that I can and will do a good job if I get back on the board.”Strauss said if he is elected, he wants to get the town of Swampscott a formal tax policy. “Having been there, it seems to be whatever the opinion of the five members are at the time is how it?s made up,” he said.At 33, Januszewski is the youngest candidate, and has only lived in town three years. The software engineer hopes to bring more communication to town residents to help bring understanding to the decision-making process. “Based on meetings I?ve been a part of, the residents in Swampscott don?t have enough information to make great decisions,” he said. “We need more participation.”Callahan, 49, also plans to bring more transparency to town politics, especially in terms of the process for new development. “People seem to be surprised when new developments and their costs arrive,” said the Greenwood Terrace resident. “Every board I went to agreed the process was broken. When something?s broken, you should stop there, back up and fix it.”Patsios, 53, believes it?s the town?s fiscal responsibility that?s broken. “I know what it?s like to work really hard and find out that there isn?t enough money,” he said. “I need to tighten my belt to live within my means, and the town needs to know they have to live within the same rules.”Patsios said budget control is the key to fixing the town?s flooding problem, lifting the tax load, and paying police and fire the proper pension.Kait Taylor can be reached at [email protected].
