Our team of Sandy Loam’s guides and instructors bring their diverse backgrounds and experiences to create an inclusive community for all.
Our Team
Aishwarya Kancharla
Director & Veronda-Falletti Ranch Property Manager
Aishwarya is an experienced program design and implementation specialist in the fields of health, healthcare, human rights, education, and environmental stewardship. Key experiences include serving as: Program and Volunteer Coordinator for the Red Door Society, a cancer support organization in New York; working as a graduate intern with the UCSF Safe Motherhood Program in Zambia and India; Senior Communications Advisor for USAID’s Rule of Law Stabilization Program in Kabul, where she supported prospective USAID grantees and outreach efforts promoting human rights and the rule of law; and Senior Project Manager at CannonDesign, advising health systems on strategy and program delivery. She subsequently launched two sister Montessori schools, gaining substantial experience in direct services and family wellbeing programs. Aishwarya came to realize that all of these focus areas were interconnected parts of the same systems of wellbeing, inspiring her to build Sandy Loam where she could connect community with arguably the most important thread holding us together: land. Aishwarya holds an A.S. in Natural Resources Management from Santa Rosa Junior College, a B.A. in Journalism & Mass Communications from New York University, and a J.D. from UC Law SF (formerly UC Hastings College of the Law). She is pursuing a Graduate Certificate in Sustainable Environmental Planning & Management at the University of Connecticut.

She looks forward to bringing her expertise and experience to Sandy Loam upon her graduation.
