MANCHESTER, NH – Most people think they’re “bad with money.” But in reality, many were never taught how financial systems actually work. Sean Dempsey, a NH author, entrepreneur, and investor offers a more unconventional approach to creating financial security.
His financial “Cheat Codes” dig into innovative ways to pay off debt, save more money, and make investments that count. He’ll be appearing Saturday March 14 from 12-2pm at Barnes & Noble in Manchester, NH to sign and discuss his latest book, “Financial Cheat Codes: How to Win the Game of Finance.”
Since the book’s launch at the start of 2026, audiences across the Granite State have turned out for Dempsey’s talks and events, reflecting growing interest in his practical approach to personal finance. He challenges conventional money advice by questioning long-accepted paths to wealth, including whether a traditional college route or default retirement plans still make sense.
His book has received strong praise from Publishers Weekly, which described it as a “colorful and unapologetic guide to financial success,” adding that “his passion is clearly evident, and he sprinkles nuggets of wisdom throughout.”
One of the most engaging elements is the video game–inspired framework he uses to present financial decision-making as a series of strategic choices rather than one-time wins. His aim is to help people better understand how small decisions compound over time.
That momentum is rooted in Dempsey’s own experience building businesses and investing across New England. As a Granite State native, Dempsey owns rental properties throughout the Northeast and has founded multiple businesses in NH. Over the past 15 years, he’s launched three marketing agencies with a combined value exceeding $7 million, along with several startups focused on short-term and multifamily real estate.
Today, Dempsey uses his real-world experience and storytelling to help individuals and families build financial confidence and make more informed money decisions. With rising costs and ongoing economic uncertainty putting pressure on households across New England, his work addresses a growing need for realistic financial guidance.
Don’t miss the chance to connect with him this Saturday at Barnes & Noble in Manchester and reset your financial game.
