Niki (Dunne) Doenz | Top 40 Under 40 2025

Age: 39

Occupation: Partner, Director and Portfolio Manager, Sandstone Asset Management

As an expert in wealth management, Niki Doenz believes the real value of money is its potential to help build the future you want to create. That perspective makes sense for a woman whose career is about helping families build generational wealth, and who uses her personal time to invest in, volunteer with, and launch community organizations for the arts and rodeo.

As partner, director and portfolio manager of Calgary-based Sandstone Asset Management, Doenz contributes to the firm’s global investment strategy. In 2021, Doenz became Sandstone’s youngest equity partner. Since then, she has helped her partners grow the firm’s assets under management by 84 per cent and has also led the expansion of Sandstone’s financial planning practice. Doenz also promotes Calgary’s startup ecosystem and sits on the Thin Air Limited Partner Advisory Committee for Thin Air Labs.

“Every investment that we look at, it’s not just what can happen over the next three or six months,” says Doenz. “It’s what that company can bring to the table for returns for the long term, and also what they’re doing in the world.”

She’s building foundations for the future of athletics and arts, too. Doenz served as a board member for the Calgary Philharmonic Orchestra from 2019 to 2024, and recently joined the Calgary Philharmonic Orchestra Foundation Board of Trustees.

In 2021, she started the Junior Rodeo Series to share her love for western heritage. Held at the Millarville Racing and Agriculture Society (MRAS) indoor arena, more than 85 kids aged two to 16 have participated, with Doenz and other community members donating approximately 250 volunteer hours annually. She has also been an active member of MRAS’s Equine Committee since 2023.

“Bottom line, I want a city that my kids will choose to call home, someplace that they can aspire to live, work and thrive, where everything is here for them.”
