We all struggle to meet the daily demands of business, family, and personal well-being. Urgent demands can keep us from proactively reviewing, planning, and managing our priority needs and best interests. We need dedicated counsel to help us explore and identify our priority needs and goals, make informed decisions, and execute on those decisions. 

Gregory services the needs of select clients by meeting and conversing with them regularly. He provides industry-leading counsel and practical application of business, tax, trust, and charitable tools and strategies to help clients achieve their objectives and best interests. Gregory helps clients execute on their decisions and accomplish their goals. He helps coordinate follow-through with the client’s other advisors, service providers, employees, family, and friends to help ensure success.

Gregory is senior counsel with Brown & Streza LLP and earned his Juris Doctor degree from the University of Notre Dame and a degree in Economics with minors in Business Management and Sociology from Brigham Young University. He is licensed by the State Bar of California and a member of the Orange County Bar Association.

Gregory also currently serves as Chairman for the UCI Planned Giving Professional Advisory Council and as an instructor and merit badge counselor for Scouts BSA on the topics of Citizenship in the Community, Citizenship in the Nation, and Citizenship in the World.

Gregory was selected as one of the “Top 25 Rising Stars” in the Southern California Super Lawyers list published by Los Angeles magazine and The Journal for Law & Politics.
