ByrdAdatto attorney Patrick O'Brien

Patrick O’Brien

General Counsel

Patrick has always had a fascination with understanding how things work.  Whether it is working on cars or becoming an expert in board game rules.  This fascination led him to focus his studies on economics at Southwestern University where after graduation he worked in margin trading with a major investment brokerage firm. It was here Patrick first experienced when a person does not understand “how things work” they can be adversely affected.  Patrick saw how a client’s decisions today will affect their results tomorrow.  This led him to proactively navigate situations to give clients the best possible outcome. This problem solving combined with his desire to see “how things work” inspired his return to school and pursuit of a law degree from Southern Methodist University Dedman School of Law.

Bringing together his passion of breaking issues down to understand how they work and desire to help others understand complex issues. Patrick’s practice focuses on state and federal health care laws and regulations, and legislative developments in health care primarily for the aesthetic industry. Patrick also provides educational and informational resources to the cosmetic and aesthetic industry by navigating all state’s regulatory landscape and assisting American Med Spa Association (“AmSpa”) in its legislative efforts. Patrick also serves as the General Counsel for ByrdAdatto and AmSpa. 

When he is not in the office Patrick enjoys spending time outdoors with his family and loyal hound dog.
