About Us

Sustaining service for meaningful impact.

At Greenleaf, our desire is for the service of others to endure as a generative force for good around the world. We bring diverse expertise and deep care to everything we do in pursuit of this vision.

Our Story: Moved by a passion for wellbeing.

Greenleaf was founded out of a deep respect for people who give of themselves to make the world a better place—and a recognition that this pursuit takes a toll on their wellbeing and their work. Witnessing this repeating cycle firsthand across the world led our founder, Dr. Siddharth Ashvin Shah, to begin Greenleaf. Since our founding, we have been privileged to come alongside organizations working around the world to help them serve more effectively and sustainably.
