Vaishnavi Lewis began following the Siddha Yoga path as a teenager in 1976. Her mother established a Siddha Yoga meditation center in their home in Philadelphia, Pennsylvania that same year.

Vaishnavi has served on staff with the SYDA Foundation over many years—from 1984 to 1993, 2000 to 2001, and once again from 2013 to 2014. She has held a variety of leadership roles, including in the Live Events and Taruna Poshana departments. She has offered seva in Gurudev Siddha Peeth, Shree Muktananda Ashram, and the Siddha Yoga Ashram in Oakland. Since 2014, Vaishnavi has been offering seva from home and as a visiting Sevite with the Content Department of the SYDA Foundation.

Vaishnavi works as a health consultant and coach and lives in Berkeley, California.
