Bryan Graves
Vice President
I have been in the plumbing and drain cleaning industry since 1989. I was in the field as a plumber service Technician from 1989 until 1995. In 1995 I took over my own plumbing location as a manager in the Bay Area. In 2000 I was promoted to their headquarters office in Auburn Ca. I moved my family from the Bay Area to Rocklin Ca in August of 2000.
I worked for my companies Head Quarters office as the Vice President to the CEO until I went into business for my self in 2006. In the last 12 years, we have prided ourselves in a 97% customer satisfaction rating. Our motto is to always strive for an outrageously satisfied customer who actively refers to Preferred Plumbing & Drain to their friends, relatives, and associates.
My personal interest is spending as much time as I can when I am not working with my family. We enjoy boating and sporting events.

Ronnie has been with the company for approximately 12 years and has served as Executive Director for 8 years. His favorite part about working as a Plumbing Director in South Bay is the diversity of projects and clients. "The area’s fast-paced growth means I’m constantly involved in innovative solutions, especially around water conservation and green plumbing codes, which California leads the nation in. Add to that the mild weather, beautiful coastal communities, and a skilled labor pool — it’s a rewarding place to build strong teams and deliver high-quality work."
