Debra Brosan MA, OD, MCC
Business Leader, Organization Development Consultant + Executive Coach
Being a catalyst for transformation is a labor of love for me—one that stems from my strong sense of humanity and passion for social justice. In addition to my work with executive leaders, I spend my time learning about business and strategy.
When I’m not working, I enjoy volunteering with the Aquetong Watershed, cooking, and spending time with my grandkids and family.
