J. McKay Tucker, Esq.
Born and raised in Mesa. Built this firm for the people he grew up around.
About
McKay grew up in Mesa. He left to study economics at Brigham Young University, went on to Arizona State University Sandra Day O'Connor College of Law, and spent time working alongside some of the most sophisticated estate planning practices in the country — serving founders, executives, and ultra-high-net-worth families whose plans involved the kind of complexity most attorneys never encounter.
What he brought back home was a conviction that took shape slowly over those years. The thoroughness. The real conversations. The sense that every client's situation deserved genuine thought regardless of the dollar amount involved. When he came back to Mesa — where he grew up, where his family has roots going back generations — he wanted to build something that brought that standard home. Not just for the wealthy. For everyone.
Mesa Estate Planning is the firm he built around that idea.
What McKay focuses on
McKay's practice centers on estate planning and business law for Arizona families, business owners, and high-net-worth individuals. He works on revocable and irrevocable trust structures, powers of attorney and healthcare directives, business succession planning, entity formation, QSBS planning, asset protection, and estate and charitable tax strategies.
Before founding Mesa Estate Planning, McKay worked at McCullough Law, where his work spanned complex trust structures, multi-generational estate planning, and business transactions for clients at the highest levels of wealth. That experience shapes how he approaches every client — with the same rigor and attention to detail, regardless of the size of the estate.
On working with clients
McKay's approach to client work comes directly from watching how the best practitioners in the field operate. The most sophisticated estate planning isn't just technically correct — it's understood. A plan that sits in a drawer because the client never fully grasped what it does is not a good plan.
Every client McKay works with gets a recommendation they can explain, documents they've reviewed before signing, and funding guidance they can actually execute. The goal isn't to produce paperwork. It's to produce clarity.
Background

Clients benefit from McKay's preparation and Jay's depth — a combination that gives this boutique firm a level of collective experience most solo practices can't offer.
