Colleen’s of Medford Square welcomes author Chuck Merrill, aka “Mr. Colleen,” who will be signing copies of his new book, “Shit You Need to Know That Nobody Bothered to Tell You: A Perpetual Guide to Life for Everyone.” Merrill wrote the book for his niece, Katelyn. It is a humorous mixture of advice regarding things such as dating, weddings, funerals, neighbors, in-laws, money, careers, and more. Stop in and catch up with Clark, whose late wife, Colleen Hallisey, owned and operated Colleen’s for 30 years.
