The firm

Two decades of Arizona business law, in one focused practice.

Founded in 2005, Crampton Law Firm brings decades of seasoned insight to the table. We reject the impersonal nature of "Big Law" in favor of a deeply tactile, relationship-driven approach.

Whether drafting meticulous estate documents or navigating high-stakes commercial litigation, we act as steadfast stewards of your legacy. For the same clients, often for decades.

Meet Liz
In their words

What clients say about working with us.

Liz has been our outside general counsel for nearly a decade. Every contract, every employee issue, every M&A conversation runs through her first. The institutional memory she has of our business is irreplaceable.

We came to Liz after a partnership dispute had already turned ugly. Her ability to see the legal and the human side of the situation at the same time is what got us to a settlement we could live with.

When we sold the family business last year, Liz had been our counsel for eighteen years. The transition would have been impossible without that history. She knew the company better than most of our own employees did.

Working with Liz on our outside general counsel engagement has been a quiet upgrade for the whole company. Faster answers, fewer surprises, and a clearer paper trail behind every decision we make.

I came in needing an LLC and a buy-sell agreement. Twelve years later Liz still handles the entire legal side of our business and our family's estate. She has earned every bit of that trust.

Liz restructured our four-restaurant LLC after our partnership shifted, and she did it without disrupting day-to-day operations once. The transition felt like a non-event, which is exactly what we wanted.

When my father passed, our family was scattered across three states with strong opinions about what should happen next. Liz walked us through probate with the patience and clarity we badly needed.
