David Cropper joined the management board of Longevity Partners INC in September, the group’s fully owned subsidiary in the United States. David brings with him over 37 years of experience and leadership in real estate development, including project design, entitlement, construction, and finance. 


Until 2021, David was the Director of Development at TMG Partners, where he was responsible for all development activities in the greater San Francisco Bay Area. He is currently on the board and has served as past Chair of NAIOP Silicon Valley.  He is also active in the Urban Land Institute where he has served as a board member of both the San Francisco and Silicon Valley chapters and where currently serves on the Silicon Valley steering committee and as a member of the Residential Product Council.  He is also the chair of the Urban Land Institute’s Sustainable Development Council.

“I am very excited to take on this position at a time when sustainability and climate change are increasingly critical topics to the viability of our businesses, our communities, and our world. I come to this position after 25 years in the real estate development and investment business in the San Francisco Bay Area.  As with many firms in the Bay Area, the needs of Longevity Partners’ clients and stakeholders are changing rapidly. I am grateful to be on the board of such a young and dynamic firm to ensure that Longevity continues to have a positive impact on all stakeholders and society as a whole,” says David. 


Etienne Cadestin, Founder and CEO of Longevity Partners said: It’s a real honor to have Tamar and David join our global and US boards. Together, they bring more than 50 years of experience and leadership in consulting and responsible property investment. Their vision, knowledge, and leadership are exactly what we need as we expand our operations internationally and innovate our business models to become the leading independent global ESG advisory and investment firm to deliver the transition to a low-carbon world and address the imminent climate and biodiversity crises.”
