SANFORD CARL LOEWENTHEIL

Co-Founder & Vice Chairman, L+M Development Partners



Sanford Carl Loewentheil was born in New Rochelle, NY. After graduating from Washington University in St. Louis in 1976, Sandy, a third generation builder, joined his family’s business building luxury single-family homes and condominiums in the suburban New York and Connecticut area. In 1984, he co-founded L&M Equity Participants (currently L+M Development Partners) where he now serves as Vice Chairman. L+M has evolved into one of the premier real estate construction, development, finance and management companies in the field of multi-family and mixed income housing. Today, the company employs over 200 individuals in its Westchester County and New York City offices. To date, L+M has developed and built over $3-billion dollars of housing created for its own portfolio

Sandy’s primary business focus at L+M is the construction division. L+M has built well over 10,000 residential units and one million square feet of retail space, most of which are still owned by L+M and its partners and managed in-house. Over the years, the company has helped raise the bar of quality housing in its industry. L+M has developed and continues to enjoy long-term relationships with subcontractors, banks, joint venture for profit and not for profit partners and investors for almost 30 years. In addition, L+M currently manages several private equity funds investing in inner city development.

L+M has been dedicated to pro bono community involvement since the company’s inception as such community minded work is a central tenant to the L+M organization. Some pro bono projects include scholarships at local high schools, rebuilding local churches and parks, working with at-risk youth, mentoring minority builders, fostering local sports in urban areas and creating preschool programs.

Outside of the office, Sandy is passionate about providing scholarship support for students graduating from local urban high schools. He believes that deserving students should be able to achieve their true potential and attend college despite any restrictive financial circumstances. To achieve this goal, he and his wife, Karen, have endowed multiple college scholarships and funded a significant number of annual scholarships.

Sandy currently serves on the National Council of Arts and Sciences as well as on the Board of Trustees at his alma mater, Washington University in St. Louis. He recently received the NY Regional Award as well as the Arts and Sciences and the University Distinguished Alumni Awards. Sandy served as co-chair of the Arts and Sciences and co-chair of the New York region committees in a $150,000,000 scholarship campaign at Washington University that has surpassed its financial goals.

Sandy is a member of Rye Country Day School’s Board of Trustees and is a member of the board’s executive committee. A founding member of Sulam Yaakov Synagogue in Larchmont, NY, Sandy sits on the synagogue’s Board of Trustees as well.

Sandy resides in Purchase, NY with his wife Karen and their three children, Hannah, Adam, and Sarah.
