Sullivan Development Services started as a way for me to work on multiple startup projects under one umbrella organization. Throughout the years I've completed worked with startups, small businesses, and local groups in the Berkshires and Pioneer Valley. Whether it's setting up social media pages, building out a website, or developing a strategy for your entire business...I can help with whatever you may need!
