Today’s guest is Mark Hays, Director of Sustainable & Impact Investing at Glenmede — a firm managing $48 billion with a client-to-employee ratio that keeps conversations personal and strategy focused.

Mark’s journey into finance started early — running a lemonade stand to save up for a Sega Genesis and learning about markets through a third-grade stock project that didn’t go as planned. That early curiosity eventually led to a career spanning Cambridge Associates, OMERS, Flat World, and J.P. Morgan — where he became the firm’s first U.S. sustainable investing hire.

Now at Glenmede, Mark helps clients align their portfolios with their principles — not just in theory, but through tangible investments.

Glenmede offers investment management, wealth planning, fiduciary, and advisory services to high-net-worth individuals, families, endowments, foundations, and institutional clients.

It has $48 billion in assets under management, but keeps a 4-to-1 client-to-employee ratio and promises, in Mark’s words, “the experience of a $200 million family as a $10 million individual.” That approach means every client gets tailored advice, deeper conversations, and impact reporting that goes far beyond ESG scores.

Nearly 20 percent of AUM sits in strategies that fit Glenmede’s four-category investment taxonomy (Integrated, Mandated, Thematic, High-Impact Concessionary) and span almost every asset class.

Mark’s through-line is what he calls “sustainable prosperity” — the belief that helping those with the least doesn’t take away from others, but actually creates more opportunity and value for everyone.

At Glenmede, that vision shows up not only in where the money goes but in how clients are engaged. Mark and his team don’t just plug people into products — they guide multi-generational families through deep, often difficult conversations about values, legacy, and measurable impact.

That means starting with inquiry, moving through education, assessment, and implementation, and ending with real measurement — not in vague ESG scores, but in tangible results like gallons of water saved, emissions avoided, or communities reached.

Mark knows that impact is a moving target, but he also knows how to hit it: by staying curious, staying human, and staying honest about what money can and cannot do.

Tune in to hear how he turns that approach into measurable impact.
