Parzival Therapies utilizes the HANDLE® approach combined with Functional Nutritional evaluations, to get to the root causes of  our clients concerns by providing effective, non-drug evaluations and interventions for recovery from NeuroDevelopment and Degenerative challenges. Our focus is providing therapy for clients on the autism spectrum and those with ADD, ADHD, learning difficulties, perplexing behaviors, sleep disorders, issues related to aging, and more.

We have an extensive personalized interview process, and then observe our clients during structured activities or play. We then create a therapeutic plan to acknowledge, validate, and work with each individual’s challenges. This plan will include health and nutritional recommendations. 

We’re excited to help you work through your needs and come out on the other side happier and healthier than before.

Our Mission:

Parzival Therapies is about transcending limiting labels and providing tools that enable and empower every human being to live the most stress-free, inspired life possible.  Helping Extraordinary people do ordinary things.


Parzival Therapies combines an understanding of neuroplasticity* and the interplay among mind, body and environment to help the brain gently change itself. It’s designed to enhance neurological systems that are causing learning or life difficulties, without force or judgment.  We can assist children and adults labeled with, but not limited to:

The HANDLE approach is based in the philosophy of Gentle Enhancement®, the concept that slow, steady, supportive movement over time provides the best results, the HANDLE program helps enhance the functioning of the brain and body through a compassionate approach that taps into the body’s natural ability to reorganize and improve itself. 

Every individual is unique, so HANDLE is not a one size fits all approach. In fact it is a philosophy that is rooted in acknowledging, validating and working with each individual’s differences.

Gentle Enhancement

Gentle Enhancement describes the HANDLE process of respectfully supporting sensory processing in small steps without undue stress, recognizing that sensory over-stimulation can interfere with attention and learning.  The HANDLE paradigm encourages people to apply Gentle Enhancement in their daily lives. Clients and support people are taught to watch for subtle signs of stress as indicators of when to stop a HANDLE activity.

The Origins of HANDLE®

Judith Bluestone was a remarkable woman, born with numerous neurological challenges and structural irregularities as well as injuries that left her paralyzed and in a wheelchair for two years. She had nearly unintelligible speech as a child, became profoundly deaf at age 8, suffered from clonic/tonic seizures, had groundbreaking reconstructive facial surgery, experienced repeated encephalitis and meningitis, once leading to loss of speech and other differences for which she was teased as a child and worked all her life to overcome. Despite all of this and more, Judith triumphed over her differences, finding ways that helped her make it through her early years. She instinctively protected herself in her areas of greatest vulnerability, guarding her sensitive systems while using her strengths and talents to successfully make it through school and into graduate work. Among her extensive studies were neuroscience, neuropsychology, neurorehabilitation, human development, visual processing, sensory-motor integration, education, counseling and more. Not stopping there, she studied as many alternate approaches as she could, all the while striving to understand from the outside in what she had learned and experienced from the inside out. 


Judith spent eleven years in a kibbutz in Israel, developing her ideas into a functional program that continued after she left, winning the 1989 National Prize for Early Childhood Education for the State of Israel.


Encouraged to share what she had learned and developed, Judith founded The HANDLE Institute in 1994, now present in 31 countries and growing. Since that time, research and studies have been conducted to demonstrate some remarkable outcomes for which Judith received numerous awards and recognition.


Judith Bluestone passed away unexpectedly in February of 2009.
