Olive Tree Neurodiversity Logo.  The olive tree represents how children with specific learning difficulties (SpLD) or neurodiversity, may be slow to develop in certain areas, but they still have a lot of value to add.  Nobody underestimates the value of an olive tree.

“Marlene was very professional and made me and my son feel at ease when he was a little nervous before his assessment. Marlene has also helped us both to understand his feelings, and supported us in getting the help he needs at school.”

“Olive Tree Neurodiversity has been instrumental in helping us navigate
our son's ASC, Marlene delivered beyond our expectations. We were given useful tools for parenting the neurodivergent child through a very considered and non judgemental approach which in turn had an enormous impact on the entire family dynamic. Marlene of course provided us with great insight and resources, but we consider the hope that she planted and her encouragement to go deeper into our family values to be the most valuable aspect of her mentoring. ”

“Marlene is an excellent addition to my son’s education. After being diagnosed with Dyslexia we wanted him to have tuition that would suit his learning and cater for his specific needs, Marlene sure has done that. Each week the sessions are varied, interactive and fun and our son looks forward them. Marlene’s patience and understanding create a positive and calm learning environment, I highly recommend. ”
