Castro Valley Plumbing & Heating, Inc. was founded in 1990 as a commercial and industrial plumbing contracting company specializing in design build by Chief Executive Officer Richard C. Mar. The company has proudly been family owned and operated since its humble beginnings. Richard started his company with a small rental space for a warehouse and his spare bedroom as an office. His wife Kerrie, now the Chief Financial Officer, took care of the bookkeeping at nights while working her day job and raising their two children, who now both hold positions within the company.
