Jeff Hartmann is the co-founding member and serves as President of Elm Tree Communities (“ETC”), a private real estate company. In this capacity, he develops, implements, and oversees ETC’s development strategy as well as all capital markets activities.  


With more than two decades in CFO, COO and CEO capacities, Jeff Hartmann has played a crucial role in the creation and development of the hospitality industry. His career spans the landmark casinos of Foxwoods and Mohegan Sun in Connecticut, and Mohegan Sun at Pocono Downs in Pennsylvania. 


Clients have benefited from his breadth of experience and expertise, including understanding the risks and opportunities in real estate, real estate due diligence including financial modeling, following the use and selection of cap rates, proforma development analysis, development feasibility analysis, ground leases, working with REITs and Private Equity Funds. 


Jeff has addressed wildly divergent opportunities along the way. From acquiring the WNBA Connecticut Sun franchise for the Mohegan Sun to leading the Mohegan Sun Executive team in developing the property master plan as well as developing a mixed-use entertainment zone at Harrah’s Cherokee Casino in North Carolina.  


Jeff has worked closely with major Wall Street firms including Goldman Sachs, Citibank, Wells Fargo and Bank of America. As Chief Financial Officer of the Mohegan Tribal Gaming Authority, he played a pivotal role in securing $4-billion in public and private financing, including the only $1-billion syndicated bank credit facility for a Native American tribe. 


Since founding Elm Tree Communities in 2020, Jeff Hartmann has served as President of the firm, which specializes in multi-family, mixed-use real estate and hospitality projects. Today, Jeff and his associates at the Elm Tree are creating next-generation multi-family developments that reflect the shifts in residential and lifestyle design.


It may come in the form of consulting for property owners, advising on real estate financing or mixed-use real estate profitability. That next challenge may turn on 30+ years of financial acumen, or the insights garnered from working with elite finance, hospitality, and real estate professionals. 


Jeff began his career as a Certified Public Accountant with PricewaterhouseCoopers, LLP, working from 1984 to 1991 in the Philadelphia and New York offices as a specialist in real estate and casinos. He earned his Bachelor of Arts from Rutgers University and earned a Certificate in Real Estate Development from New York University Schack Institute of Real Estate.
