Catherine Carr, MBA
Director of Operations
I am passionate about optimizing processes and workflow, especially the client journey. By leveraging business management experience acquired at PwC and other consulting firms I am able to bring a valuable approach to the review, analysis, and evaluation of the firm’s business policies and procedures. Additionally, I work closely with the managing attorney utilizing a data-driven approach to craft strategy and finance.

I currently manage engagement operations at the firm to help ensure client matters are handled in the most efficient manner possible. I attended Texas A&M Commerce and graduated with a degree in Psychology, which I feel has given me the ability to connect with clients, while displaying compassion and empathy, as we help them navigate difficult situations and periods of their life.

I enjoy working with people and have a strong desire to help others succeed.
