Brittany Gray

Before joining the Petersen Rothermel Law Firm in February 2019, Brittany found herself in occupations that encouraged productivity, compassion, and reliability. With just over 8 years prior experience in customer service, she has learned how to accommodate others while adapting to her surroundings. She has also spent several years volunteering at various share houses, food banks and attending multiple fundraisers. Brittany most recently serves as a Legal Assistant specializing in Family Law. She is determined to provide the best service possible to both the firm and the clients. She understands the lasting impact that a family law proceeding will have on each client’s life and is dedicated to handling each case in a respectful and supportive manner. Brittany presents a calm, professional, and supportive demeanor as she handles client’s immediate needs. While our clients experience open and frequent communication with their attorney, she is an additional liaison between the clients and the firm. Brittany is relied upon by the attorneys for drafting necessary documents, meeting directly with the clients, scheduling appointments, and court appearances, as well as keeping the client files organized. While being a full-time mom to two energetic daughters is one of her greatest accomplishments, she is excited to see where her career in the legal field will go!
