Slagel Investment Management
Slagel Investment Management was founded in 1990 by Thomas Slagel, who serves as President. The firm is based in Houston, Texas, a hub for energy finance. Cindy Slagel holds the role of Chief Financial Officer. The firm focuses on energy, infrastructure, and real estate investments. It deploys capital through direct ownership, joint ventures, and private partnerships. The portfolio includes midstream energy assets and commercial real estate. Slagel emphasizes long-duration holdings rather than trading. Total AUM has not been publicly disclosed, but public filings suggest assets under $1 billion. The firm operates a lean team out of its Houston office. No philanthropic vehicles or operating companies are publicly associated with the firm. Slagel's structural differentiator is its concentrated, patient capital approach. The firm avoids broad diversification, instead building deep positions in energy infrastructure. This model resembles that of a single-family office but operates as a registered investment adviser.
