Soma Mukhopadhyay

Executive Director and creator of RPM (Rapid Prompting Method) 

Soma Mukhopadhyay lived in India until 2001, homeschooling her autistic son Tito Rajarshi Mukhopadhyay. Since speech-communication was not easy for Tito, she taught him how to spell on a typewriter, later on a computer, as well as handwrite independently. Soma and Tito were featured in a BBC documentary "Tito's Story." By then Tito aged 11 had already handwritten a book Beyond the Silence which was published by the National Autistic Society (UK).

The Cure Autism Now Foundation invited Tito and Soma to the USA after they watched the BBC documentary. The parent members of the organization asked Soma to try her teaching method on their children. The success of her teaching technique on seven non-speaking and two selectively-speaking students with autism earned her a fellowship to implement her technique with other students in Los Angeles. Her work was featured in the "60 Minutes" television program and Soma’s technique began to be called the Rapid Prompting Method (RPM).

The popularity of RPM began to grow and parents developed HALO,  offering Soma a full-time work environment. Soma continues to offer her services through HALO camps, workshops and training for teachers and parents.

Soma and Tito have been featured in the BBC documentary and "60 Minutes," as well as CNN, the HBO documentary "A Mother’s Courage,"
National Geographic Magazine, Scientific AmericanPeople Magazine, and The New York Times.

Soma has a B.S. in Chemistry (honors), M.S. in Inorganic Chemistry, and B.Ed. in Education.

She is on the advisory board of the "Talk School" in Pennsylvania.

Parent Advisors to HALO


Sue Finnes (U.K.)

Parent Advisor

Sue is passionate about sharing what she has learnt in order to help others. Her son Christopher, is the reason Sue became involved in RPM.  Chris had autism, was non-speaking, had huge sensory issues, dyspraxia and epilepsy and was classed by the so-called experts as "low functioning."  Sue had been teaching Chris using the Rapid Prompting Method (RPM) since 2011, which was when they were first able to see Soma Mukhopadhyay for a few sessions in the UK. This was a life-changing experience – straight away Soma started teaching Chris age-appropriate educational topics – the first session included an analysis of a poem!


Chris tragically passed away in February 2023, and Sue is determined to carry out his wishes that all students like himself be provided an opportunity to find their voice.

Sue was so inspired by what she has seen Chris and other students achieve that she decided she wanted to empower more parents to learn and use this method with their children. In 2013, she created the international Facebook RPM parent-learning group "Unlocking Voices - Using RPM." Using her skills honed as a Senior Training Manager at Lloyds TSB, she helps others to learn the RPM method, working closely with Soma to ensure that accurate and up-to-date information is provided to parents. Sue works hard to answer parents' questions promptly and to create free learning resources/videos for this group.

In the UK, Sue has set up a not-for- profit Community Interest Company called "Unlocking Voices - Using RPM." She hosts workshops and gives presentations along with Alexandra Hopwood, the UK Soma-certified RPM provider. Sue was honored to be a parent speaker at the HALO-RPM conference in 2017 and has provided input to many of Soma’s books. Sue takes no fees for anything she does – it is all voluntary.

Parent Advisor

Meredith, who has an M.S.W. from Tulane University specializing in Children & Families, taught play work to autism families and served as the teacher of a fully integrated non-verbal autism/neurotypical classroom in her area before finding RPM.


She is the creator and administrator of the RPM Homeschooling Parents’ Facebook group with over 850 members worldwide and also teaches RPM online via group classes, 1-1 sessions and aide & parent training.


Lisa Bailey (Canada)

Parent Advisor

Lisa Bailey began teaching her son Fox with RPM in May 2014. She was looking for a new educational method geared towards non-verbal autistic students which would not be focused on extinguishing behaviors or repeatedly drilling basic skills. That year, Lisa travelled to HALO with her son to do a 4-day camp with Soma and found what she was looking for and so much more. RPM was completely transformational. It not only improved Fox's quality of life, but also that of their whole family. 


As Lisa’s passion about RPM grew, she wanted to help others also achieve success with it. So in 2016, she became a certified RPM Practitioner and in 2018 she co-founded RPM Connections. She now works with students all over Ontario. Lisa is also a moderator of the RPM Homeschooling Parents’ Facebook group, its mission is to help parents learn how to do RPM at home with their children. RPM — which Soma continues to develop and innovate — is a perfect match for Lisa’s belief in lifelong learning and growth.
