Dayn A. Holstrom, CFLS*

Managing Partner

Dayn Holstrom has distinguished himself and his team as the number one family law firm in Orange County, Riverside, and San Bernardino. His highly experienced attorneys and support staff are exceedingly knowledgeable and support all of their clients with the heart and determination to see your case through.

His commitment to excellence is evident throughout his numerous lifetime achievements. While attending Western State University College of Law, he received the American Jurisprudence Award for the highest achievement in a specific subject 17 times, more than any other student. He was Editor and Chief of the Western State University Law Review and Director of the School’s Don Program for tutoring other students. Dayn Holstrom was Valedictorian, and graduated summa cum laude with the highest GPA in the history of the school.

Attorney Holstrom was admitted to practice law on June 11, 1990. That same year, he boldly opened the Law Office of Dayn Holstrom where he was dedicated to perfecting his skills, resources and efforts to resolving divorce, family law, estate planning, and appellate issues. As the firm expanded and more attorneys joined the team, he founded the firm of Holstrom, Block & Parke in 2008.

Mr. Holstrom is exceptionally experienced and well thought of by the local bar associations and judiciary in the communities in which he practices: Orange County, Riverside County and San Bernardino County. He has been voted “Best Lawyers” by Inland Empire Magazine, OC Metro Magazine and has been consistently rated 10.0 of 10.0 by Avvo.

While not in the office, Dayn enjoys sports, traveling and spending time with his wife and four grown children. He is a certified pilot and loves to fly anytime his schedule permits.
