“Having my own autism assessment through Portland was a turning point. Their approach is thorough, respectful and rooted in a neurodiversity-affirming perspective. It’s not about fixing people or labelling them, it’s about understanding how your brain works so you can truly thrive.

Portland Assessments provide a fantastic opportunity for people to gain clarity, feel validated and get the right support. Their process is clear from the moment you visit the website. The assessment feels comfortable and easy to follow.” Carrie Austin, Wired Differently Sensory Seekers

“India made the whole process very relaxed and stress free. Her understanding of my grandsons needs and difficulties, was exceptional. The report has provided us with a clear way forward. As a family, we now able to move in the right direction in addressing his future educational requirements.” Family Member of Portland Assessments Client

“Thank you so much again India, I feel like the weight of the world has gone off my shoulders and I’m finally starting to understand myself a little more. I genuinely can’t thank you enough, you may have just changed my life for the better by empowering me to move forward now and meet my needs. I’m going to try and save up to probably go through the formal diagnosis process with you all when I can.” Neurodiversity Screening Client

“Excellent service, quick time line between assessment and decision. Both made me feel comfortable in opening up about my life history. Was nice to see positive comments about myself as a person. Started noticing some traits in myself that I didn’t know I did until the assessment which will help me moving forward.” Autism Assessment Client
