A Statement of Reassurance Regarding BBC Panorama Documentary on Private Diagnostic Assessments - On Behalf of RTN Mental Health

As I am sure you know, there has been a huge social media storm regarding private ADHD and Autism diagnostic assessments. We are partnered with RTN Mental Health Solutions who are NOT part of the BBC Panorama show or faced scrutiny in any form of media since we partnered with them and helped them get to market. 
I take pride in the thousands of people we have empowered and given direct access to fast turnaround and affordable diagnostic assessments. Choosing business partnerships is difficult, but we are immensely proud of our work in helping RTN launch, get to market, and offer an incredible service that is supporting Neurodivergent kids and adults across the UK and Ireland.
You are safe with RTN, and I would never place my reputation, or the reputation of NTI in jeopardy for a service not fit for purpose. You can read the statement issued by RTN at the button below, and if you are currently deterred from seeking a private diagnostic - do not be.
You are in good hands booking an RTN Diagnostic Assessment through us.

Featured Testimonials - From Those Who Have Gone Through The Diagnostic Assessments

Cathy Patton - ADHD Assessment

My journey started with a callback from the CEO who wanted to make sure my query was done by the end of the day. He was very informative and answered my questions about qualifications and medication recommendations. I took the plunge and booked. The process flung into action and I followed along with the requested information etc. I got my initial appointment booked in and then my diagnostic appointment. I was dreading the diagnostic appointment but the lady put me at ease and felt supportive and very professional. Validation of my new condition. I felt a bit odd for a few days, just accepting it even though I had expected it. I have recommended the company to friends and acquaintances as I feel it is very good value for money. The appointment availability, extensive selection of highly qualified and varied healthcare professionals were really impressive. Queries were answered promptly and explained well. I think the price is very competitive and worth the speedy diagnosis. I am now starting to get support from an adhd coach and may investigate medication in due course. Personally I felt I needed the diagnosis to support reasonable adjustments at work especially as we return to the office and embark on a new hybrid working routine - something I have found difficult. I am now confident in discussing the flexible options I may need now that I can evidence my condition. Comparing with other colleagues my diagnosis has been much more thorough than theirs which were perhaps half the cost but less effective. I was able to explain things much more thoroughly than my colleague had as she just got a questionnaire and confirmation of diagnosis with little interest in her as a whole person. She is now struggling to deal with nhs psychiatrists and finding it very unsupportive. Thanks for all of your help and reassurance so far. Highly recommend.

Joanne Montague - Autism Assessment

Really quick turnaround from booking to getting diagnosis. Fantastic Communication throughout the process.
