About Us The attorneys at Collins & Doolan specialize in the representation of employees in Tennessee workers' compensation claims. Our firm is committed to provide responsive, aggressive, and educated service to meet our clients' legal needs.

We are located in the Cable Piano Building, third floor, next door to the Downtown Grill & Brewery. The firm provides a free initial consultation with our clients. We can work with our clients to arrange consultation times around work or family schedules. We also travel to meet with clients when appropriate or convenient.
