She is co-chair of the Estate Planning Discussion Group for the Association for Women Lawyers, a member of the American Bar Association, the State Bar of Wisconsin and the Milwaukee Young Lawyers Association, and an emerging member of the Milwaukee Estate Planning Forum.

Katie has more than 10 years of tax and accounting experience, most recently serving as a manager in the tax department at SVA Certified Public Accountants SC. Throughout her career, she has managed client tax relationships, reviewed complex tax returns for individuals, businesses, trusts, and estates, and advised clients on tax planning and compliance.
