Clarence Capital Partners

Clarence Capital Partners was established as the Green family vehicle for real-asset deployment. Gregory J. Green and Jackson Green anchor the principal group, drawing on prior roles at Bear Stearns, Jefferies and MAS Energy. The family maintains separate philanthropic entities including the Green Family Foundation and The Daniel B. & Florence E. Green Foundation. The firm targets infrastructure, natural resources and private equity opportunities. It has executed investments in energy transition projects, mobility assets and agricultural technology platforms. Geographic reach covers North America and Oceania. Confirmed holdings include the renewable natural gas platform MAS RNG Supra, sold to Kinder Morgan and CIM Group in 2022. Capital is deployed via direct ownership and select co-investments rather than primary fund commitments. The team comprises ten named principals with backgrounds in investment banking, project finance and operations. No additional offices are disclosed beyond the Delray Beach headquarters. Philanthropic structures operate separately from the investment entity. No operational events from the last 24 months appear in public records. The office maintains an integrated principal-and-operations model uncommon among single-family offices of similar scale. Several team members previously built and exited operating companies in the energy sector, supplying direct sourcing channels that bypass traditional intermediaries.
