Meet the Instructors


Amanda Smith

Amanda is a Pilates trainer and yoga teacher in the San Francisco Bay Area. After receiving her Bachelors in Urban Studies and Geography at Macalester College, she decided to move to the Bay Area to pursue her love of movement and teaching. As a Pilates instructor in Oakland, she worked alongside physical therapists for over five years, helping clients regain strength after rehabilitation. Pilates developed her attention to alignment, breathing, creating range of motion in all joints, and strengthening the body from the inside out. She transitioned easily into a deep and rich yoga practice, which she quickly realized was her true calling. Completing over 500 hours with seasoned San Francisco yogis, Rusty Wells and Stephanie Snyder, she has since co-lead her first yoga and Pilates retreat in Chacala, Mexico. Her passion is to create safe, challenging, and fulfilling yoga sessions that uplift, empower, and reconnect each person to his or her divine nature. She is so grateful to be teaching at Flex and to be able to share her love of Yoga and Pilates with you. Amanda teaches Pilates every Tuesday and Thursday @ 8am.

Nikki Verhoff

Nikki Verhoff began her exploration into yoga in 1997, while studying dance in college. A life-long mover, Nikki’s first foray into asana practice was both a support for, and a release from, a very physically demanding lifestyle. At the same time, and for more than a decade, Nikki has trained in traditional Japanese karate, which has brought with it a commitment to seated meditation as an important instrument to understanding the Self. These days, her interest in yoga has evolved to include an ongoing study of pranayama and the subtlety and power of the breath. In class, Nikki taps into the physical and philosophical influences these experiences have brought her to create an integrated practice with a focus on alignment, breath, and mindfulness. Nikki is a recent graduate of the Piedmont Yoga Deep Yoga Undergraduate Program. Nikki teaches Hatha Yoga Sundays @ 9:30am and at 7:30pm on Thursdays.

Her classes progress through a measured sequence or flow and end with deep restoration; adjustments and modifications make the practice accessible to every body.

Yoga is, for Sarah Kate, part of a lifelong study of embodiment that incorporates dance-based, philosophical, literary, and somatic practices. She enjoys teaching diverse styles of yoga, including hatha, vinyasa flow, yin, and meditation.

Tori Sovocool-Engel

“Love the hills, embrace the hills, make the hills your friend” was my motto during years of running and cycling through the beautiful bay area. I believe “No” only means you have to work a little harder to reach your goal. Tori’s passion for sports started as a young gymnast and continued through many years of competitive marathon running. Her personal highlights include running in Boston, being a guide runner to a disabled athlete in New York and finally achieving a personal best of 3:21 on a flat Sacramento course. As the aches and pains grew from running, Tori turned to triathlon racing for some cross training. Her first passion might have been running, but her life’s purpose is being a mother to two children, wife, dog walker, and chef. Tori teaches cycling class on Fridays @ 10am.
