Cullen Collimore Shirley PLLC

United States 2025

Overview

With tectonic shifts in technology and communications, matters that once required a host of attorneys to manage are now handled by elite teams a fraction of the size. We use technology to elevate our effectiveness, managing even the most complex matters efficiently and without the overhead and legacy costs other firms carry.

We are a team of attorneys with more than a half-century of collective experience litigating disputes and advising businesses. We use the considered judgment earned by our experience to identify goals and craft strategies to attain them. We are zealous advocates for our clients and tenacious in our approach to every challenge.

It is the individual talent and dedication of the professionals who make the best law firms tick. We are a select group of attorneys and legal professionals with diverse expertise and singular focus.

Our advantage is the collaboration we bring as a team. We staff matters so that duplication of effort is minimized and each task is oriented to a concrete objective. Our interest is achieving tangible results and client satisfaction, not hourly billing goals.

Our experience, tenacity, and solutions-oriented approach has gained us the confidence of the region’s top public and private companies, innovative municipalities, and forward thinking not-for-profit organizations.
