Company History

United Mechanical was founded in 2003 by Tom Sosine and Jon Gundersen. They built the firm to handle complex mechanical and plumbing projects that many contractors avoided. Over time the company took on larger commercial jobs and collaborated with major general contractors in the region.

Work has included energy-focused retrofits and projects that meet LEED Platinum and WELL Building Certification criteria. That background helps clients with high performance goals and strict code requirements.

Leadership

Founders Tom Sosine and Jon Gundersen remain involved in project strategy and local relationships. Both bring decades of hands-on experience in mechanical construction and system design. They keep close ties to Bay Area developers, owners, and facility teams to align project goals with site realities like Alameda’s mild, maritime climate and older building stock.
