Company Profile

Sturm Family Office, now operating as Alder Companies, is a multi-faceted family-led real estate development and investment management firm based in Denver, Colorado. The firm cultivates thoughtfully designed investments to generate meaningful returns and long-term value for its companies, colleagues, and communities. It manages and supports two primary business lines: Alder Ventures, its investment division, and Alder Real Estate, a privately held real estate company. Alder Companies also provides professional services, including accounting, legal, and executive leadership functions, to the Sturm Family, their partners, and their closely held businesses.

The origins of the firm trace back over three decades to the investment activities of Don Sturm, who assembled a team of experienced real estate and investment professionals in Denver. In January 2022, the Sturm Group and Realty Management Group, which constituted Don Sturm's family office and investment management firms, rebranded under the new name Alder. This rebranding aimed to reposition their extensive capabilities into three distinct branches: Alder Companies, Alder Ventures, and Alder Real Estate, building upon a history of success and integrity.

Alder Ventures, the investment arm, is anchored with significant committed capital, enabling it to navigate short-term market volatility and focus on preserving and growing long-term assets. The firm invests thematically across diverse opportunity sets, spanning various asset classes and both public and private markets. Its investment strategy includes direct co-investments and allocations to private capital funds. Alder Real Estate, on the other hand, offers a full suite of services, encompassing acquisition, development, redevelopment, management, and disposition of properties across various asset types primarily in Colorado and the Rocky Mountain West.

The leadership team includes Stephen Sturm as CEO of Alder Companies, Bryan Ritz as CIO of Alder Ventures, and Stephanie McCandless as President of Alder Real Estate. The team's expertise spans real estate, investments, and philanthropy, with a focus on ethical behavior, creative tenacity, a long-term outlook, and strong teamwork. The firm emphasizes continuous improvement, integrity, collaborative growth, and a long-term perspective in its investment approach.
