While employed with various ABA organizations, including a start-up home-based ABA company, Bridget fused together her previous background in sales, marketing, business development, talent acquisition, and ABA to solve business challenges.  Bridget’s passion lies in building long-lasting sustainable relationships by utilizing active listening skills, humility, and humor.  Her favorite saying is that her knowledge base is “an inch deep and a mile wide”, however, she is always willing to share and help where her skillset aligns.  Bridget is anticipated to graduate with an MBA from Southern New Hampshire University in 2023.
