“

I needed an accounting firm that could move as quickly as my company. My experience with firms prior to Wiss was draining my time and energy and was detrimental to growing my business. Making the decision to work with Wiss has been a game-changer for Montauk Brewing Company. Having Wiss as a partner allows me to focus on day to day tasks and the future of my company, rather than worrying about accounting issues.
