Success is not final, failure is not fatal: it is the courage to continue that counts.
-Winston Churchill


Susan Wissink is passionate about helping her clients, learning about their businesses, and helping them reach their goals in the areas of mergers and acquisitions, entity formation, loans, and general corporate matters. In numerous complex transactions, this experienced business attorney has represented both buyers and sellers, including asset and stock-based acquisitions and sales, mergers and other business reorganizations. As a Phoenix-based business attorney, she assists her clients in forming new companies, strategic partnerships, commercial loans, general corporate matters and commercial health care matters.

Helping the victims of 9/11 with their legal needs after the terrorist attacks on the twin towers of the World Trade Center in New York left a profound impression on Susan, and the experience instilled in her a lasting desire to provide pro bono services to those in need. Outside of her work as a sought-after business attorney, her favorite hobbies are spending time with her family, snow skiing, hiking, biking, and volunteering for local charities that help children or animals.
