James Thalheimer

James Thalheimer is Vice President, Finance at Diamond Equity Partners, a Jenkintown, Pennsylvania–based investment firm founded in 2009 by serial entrepreneur Peter Schorsch. In his role, Thalheimer manages operational reporting and builds financial models for potential acquisitions, and he handles key parts of acquisition due diligence. His stated skill set centers on financial modeling, private equity, mergers, due diligence, and emerging markets.

Before Diamond Equity Partners, Thalheimer worked in finance and private-equity roles in the Philadelphia area. He served as a Senior Associate at Bachow & Associates (a Bala Cynwyd, PA private equity firm) and earlier as a Financial Analyst at The IMC Group. This background gives him hands-on experience in financial analysis, M&A, and investment evaluation for private companies.

On the education side, Thalheimer earned an MBA in Real Estate & Finance from the University of Pennsylvania's Wharton School (studies dated to the early 1980s in available records). He also holds a Bachelor of Science from Brown University, with study in economics at the University of Warwick in the UK.

Diamond Equity Partners describes itself as combining "the financial and operational resources of a traditional family office with the relentlessness of an institutionally backed investment firm." The firm is affiliated with Primary Resources Group, and founder Peter Schorsch brings 40+ years of entrepreneurial experience having built more than a dozen self-funded companies. Thalheimer's finance function supports that operator-led, value-add investing model.

• Invests in high-quality growth companies with strong management teams that have moved past the startup phase into revenue generation with a clear path to profitability.
• Targets companies typically doing $5–150M in revenue and $1–10M in EBITDA (or with the ability to reach positive cash flow in the near future).
• Sector emphasis on cannabis and hemp, branded consumer products, value-added distribution, import/export, clean-tech, EVs, alternative energy, recycling, water, and environmental businesses.
• Positions itself as an operationally involved, value-add investor rather than a passive check-writer — leveraging "strong operational expertise, a deep understanding of many industries, and key market relationships."
• Emphasizes flexibility on investment size and asset class, drawing on family-office-style capital.
