Chief Operating Officer
Tracy Fletcher grew up in Kansas City and joined Verizon Wireless at a very early age. She worked through the ranks moving from state to state with the company including Iowa, Georgia and finally ending up in California. After almost 30 years of service she felt it was time to leave the corporate world behind and pursue her true passions: animals and gardening. Tracy is an avid animal activist and has volunteered for various rescue groups and shelters. Her business experience and love for gardening makes her a great fit for The Ruth Bancroft Garden. She started out as Office Manager, then Event Manager, Sales Director and now COO. She loves that each day is a new adventure and allows her to meet so many great people.

Martín Viveros is the senior gardener, having worked at the Garden since 1990. He moved to Bakersfield, California from Mexico in 1984, where he began to work in vineyards there. His cousin first introduced him to the Bancroft's in the late 1980s and he soon moved to the Walnut Creek area to begin work in Ruth’s garden. He did not know much about cactus and succulents at the time and Martín said at first he did not enjoy working with the especially spikey cacti. He wondered how Mrs. Bancroft could handle them without wearing any gloves. After six months though he began to really enjoy the job, though he does wear gloves when working with cacti. He currently divides his time between Mrs. Bancroft’s private gardens and the Ruth Bancroft Garden. Mart ín also has his own landscaping business, and enjoys cooking for a special event catering business he created called “Tacos Michoacanos” providing signature dishes for weddings and other private gatherings.
Walker joined the staff at RBG in January 2012 and since then has come to function as custodian of the Garden’s aesthetic. He acts as point person in the collaborative process of preserving, renovating, and rejuvenating Mrs. Bancroft’s beds, taking particular joy in sculpting undulating mounds and arranging rocks in the Garden to form a unifying backdrop and compositional foil to the Garden’s plant collection. Along with the curator he propagates rare succulents from seed to be used in the Garden and manages care of the private collection. His most significant contribution to the plant palette has been the donation of a cycad collection, which he has used as an intermediate texture connecting the garden’s collection of radially symmetrical rosettes with its softer drought-tolerant herbaceous perennials.
