Mario has recently joined Beyers Costin Simon. He is overjoyed to be a part of a firm with a diverse group of experienced attorneys who have set a standard of excellence that he strives to meet with every client.

Mario brings a diversity of thought to the firm. After spending almost seven years on active duty as a Marine Officer, he brings a unique blend of discipline, strategic thinking, and leadership to his legal practice. His military experience honed his ability to navigate complex challenges and make critical decisions under pressure, skills he now leverages to advocate effectively for his clients.

Mario was raised in Santa Rosa and now lives in Windsor. He is deeply connected to Sonoma County, and outside the office, he enjoys golfing, skiing, hiking, and camping. Still, more than anything else, he cherishes spending quality time with his wife and son.
