About me

Tammi practices in the areas of probate and estate planning, corporate law, real estate, and employment law. She also practices municipal law, serving as Solicitor for the Villages of South Vienna and Catawba.

As an estate planner, Tammi supports her clients through the complicated process of identifying their assets and determining how they would like to transfer those assets to their family members, friends, and charities. She finds this work deeply satisfying “because of the relationships I develop with my clients. They feel comfortable talking openly to me about their lives, as they should. I make sure there is a sense of reassurance and trust.”

Tammi’s corporate law experience gives her the skill to help estate planning clients with complex business succession issues. Her expertise also allows her to guide clients through the process of buying and selling businesses and the full range of corporate transactions. Tammi enjoys the challenge of working with her many clients who bring their business acumen to Cole Acton Harmon Dunn.

Tammi is a classically trained pianist, having earned her Masters in Music before she went to law school at the University of Dayton. She is an active member of the choir of First Lutheran Church in Springfield, her musical outlet today. Tammi and her husband have a son who is a graduate of Wittenberg University, her alma mater, and who works as an excess insurance underwriting associate in Atlanta, and a daughter who is a high school student at Northwestern High School in Clark County.
