Lindy Joffe, OTR/L -- Pediatric Occupational Therapist

I moved to the United States from South Africa in 1976 just before my seventh birthday. Due to differences in the organization of the school year in the two countries and my late summer birth, I jumped into second grade with only a couple of months of first grade under my belt. I had a funny accent, and I couldn’t read. Though I caught up quickly with help, the feelings brought up by my placement in a remedial reading group stayed with me for years. I am now stronger for this experience. This early school challenge feeds who I am as a pediatric OT, and is an essential part of how I came to this profession.

I first learned about occupational therapy while working with adults with developmental disabilities as a vocational rehabilitation support person after graduating from UC Berkeley. I was captivated by OT’s range, and returned to school to pursue my master’s degree. After completing my studies at Columbia University in 1999, I returned to the Bay Area to practice full time in pediatric settings.

As a practitioner, I am fascinated by the ways in which the motor and sensory systems, particularly the visual-vestibular-auditory triad and underlying reflex systems interact with cognitive perceptual skills to propel an individual's problem solving abilities. I love working with the kids, but I am equally passionate about working with families and teams of professionals that coalesce around each child’s needs. I am also committed to being able to translate complex concepts to people from different professional and layperson backgrounds. As such, I have taught both parenting workshops and continuing education courses locally and nationally. In 2005, I opened the clinic Kidspace in San Francisco with partners. I stepped out of the ownership role 4 years later, and continue to work out of Kidspace as a private practitioner 3 days per week. I also work one day a week out of Full Circle Development Center in Oakland.

My postgraduate occupational therapy education includes the following: Therapeutic Listening/Advanced Therapeutic Listening, varied Masgutova Neuromuscular Reflex Integration (MNRI) Protocols, the Perceptual Enrichment Program, DIR/Floortime, Handwriting without Tears, the Wilbarger Protocol, amongst others. I have studied a range of sensory integrative principles and executive functioning concepts, and have taken additional courses that focus on the integration of regulation with the emotional, attentional, and engagement systems. When I’m not working, I spend time with my partner, two children, friends, and animals. I have many other hobbies that I dream of returning to as time allows!
