Michael Covarrubias Retains Dual Role of Chairman and Co-CEO
SAN FRANCISCO (April 28, 2026) – TMG Partners, one of the San Francisco Bay Area’s largest mixed-use property developers, today announced Ben Kochalski Co-CEO with Michael Covarrubias who also remains Chairman. Ben will retain his role as Chief Investment Officer.
“Ben hit the ground running with his strong leadership skills and ability to bring our multiple teams at TMG together, which has been key to our development efforts and capital formation success across the Bay Area,” said Michael Covarrubias, TMG Partners Chairman and now co-CEO. “His strategic vision and ability to identify projects and bring them to fruition through creative solutions has aligned with both short- and long-term goals for the company – so this expansion of his roles will only strengthen our ongoing and future opportunities, especially with our renewed focus on San Francisco’s Downtown.”
Most recently TMG President and CIO, Ben joined the firm as Regional Partner in 2019 and, as a member of TMG's Investment Committee, led the investment strategy for the company, including all acquisitions and dispositions, while supporting the firm’sdevelopment activities. He was instrumental in the repositioning of 350-380 Ellis that is now fully leased to OpenAI, and closed the acquisition of 149 New Montgomery – now 60% leased – located at the nexus of the South Financial District, SOMA, and Downtown.
TMG has demonstrated its commitment to San Francisco and Downtown through strategic acquisitions and strong support of the Downtown Development Corporation. As such, Ben is overseeing improvements to the Metreon through structural renovations, a more diverse retail mix, and the reimagining of the rooftop event space. He is also leading the team’s massive transformation to the Macy’s building on Union Square that TMG is reinventing after entering into a joint venture with the parent company.
“I have enjoyed the challenges of the mix of properties – from office to retail – that we have taken on during what has been challenging, if not turbulent years,” added Ben. “It’s the determination we share across the TMG team that inspires me, and I am ambitious to expand my opportunity to lead us to the next level.”
Prior to TMG, Ben was principal and director of John Buck Company's JBC West division. Since opening their San Francisco office in 2011, he managed and grew it while leading high profile projects such as Park Tower and One Steuart Lane. During his time at The John Buck Company, he was responsible for over $2.7 billion of acquisitions and dispositions and his responsibilities included implementation of investment strategy, oversight and coordination of the West Coast investment activities, joint venture structuring, and the origination of new investment opportunities for the firm’s West Coast regional office.
Ben holds a Bachelor of Applied Science degree from The Ohio State University with a (BASc) in Civil Engineering, and a MBA in Real Estate Management, Finance, Entrepreneurship and Innovation at Northwestern University’s Kellogg School of Management. He resides in the Bay Area with his wife and three children.
