Meet The ITS Team

History of ITS

Irvine Therapy Services was founded in 1980 by Betty Romero, MA, OTR/L, at the suggestion of Dr. A. Jean Ayres, pioneer, researcher and teacher in the field of sensory integration and occupational therapy.  Dr. Ayres saw the need for a pediatric occupational therapy practice that utilized the Ayres Sensory Integration® techniques in Orange County. ITS thereby became the first pediatric occupational therapy clinic to open its doors to the children of Orange County in November 1980 . 

When Betty retired from the practice in 1996, Priya Mohan, MA, OTR/L took over as Director of Irvine Therapy Services. Priya recently retired in August of 2021 and the practice is now run by Aparna Guttery, MA, OTR/L and Jennie Ni, MS, OTR/L, previous ITS employees. Aparna and Jennie have diverse, pediatric experiences and have each been working as occupational therapists for over 20 years, bringing a collective 40 years of knowledge and experience caring for children and their families. They are looking forward to expanding ITS to provide speech therapy and other services to empower families and the community.

Our Amazing Team

Our highly qualified professional staff consists of Licensed and Registered Occupational Therapists (OTs) and Speech Therapists (SLPs). Our OTs  have advanced training in sensory integrative evaluation and treatment techniques. We are certified in the administration and interpretation of the Sensory Integration and Praxis Tests (SIPT). Our SLPs are also familiar with sensory integration and incorporate that understanding in their therapy when appropriate. All our therapists have extensive backgrounds in child development, play, neuroanatomy, neurophysiology, kinesiology, sensory-motor functioning, oral-motor functioning, hand function, handwriting, and psycho-social behavior. We use a holistic approach, and work with families and other professionals to enhance the quality of life and the functional abilities of the children we treat.
