Client L♥ve

“I’ve transitioned to prenatal centered classes and it makes all the difference in the world.”

My body was changing so much and my mobility is getting more and more limited. Stephanie’s cueing is SPOT on to activate and relax appropriate muscles for us preggo mamas (especially with respect to the deep core and pelvic floor).

– Charisse B.

San Francisco, Pelvic Floor Physical Therapist

“Stephanie’s postnatal classes have been instrumental in helping me regain my body”

She completely understands the challenges and trauma of a new mom’s body and is both mentally and physically supportive of the evolving body after giving birth. I love being surrounded by a warm, welcoming community of mothers and look forward to the class every week.

– Jennifer M.

San Francisco

“I’ve worked with other trainers over the years, & have found Stephanie to be clearly one of the best.”

She is knowledgeable, patient, & completely committed to helping you change your body for the better, forever. When I first started seeing her, I was having backaches from postural issues at work — she helped me fix the problem with a whole-body approach.
