About Reach&Root

Reach&Root Partners was founded on the idea that we achieve more and better when we ground ourselves in the fundamentals.  We believe that sound impact measurement practices lead to enhanced outcomes and unlock more capital.  In our advisory practice, we focus on the U.S. housing market. In our network building work, we focus on individual impact investors in and around San Diego. At the center of it all lies responsible investment practices and a belief that strong community sustains us all.

​

Reach&Root Partners was founded by Rachel Mavrothalasitis leveraging over 15 years of experience in non-profit and for-profit sectors designing and implementing results-driven programs.​
