What our clients say

  • "Ashleigh helped me return to work in just 12 weeks"


    "After being signed off work for six months due to panic attacks and severe depression, Ashleigh helped me return to work in just 12 weeks. Her professionalism and empathy were invaluable. I regained confidence in everyday activities and saw a huge improvement in my relationship with my wife and daughter. I will always be grateful for the support Ashleigh provided."

  • "I'm happier and finally living the life I want"


    "I was initially sceptical about therapy, but Brad quickly put me at ease with his professional yet friendly approach. He explained the process clearly and made sure the treatment plan made sense to me. I felt genuinely supported throughout. Thanks to Brad, I was able to work through trauma I thought I’d never overcome. I’m happier and finally living the life I want. His approach was transformative, and I’m incredibly grateful for the skills I’ve gained."

  • “Ashleigh helped me and my parents more than I ever could imagine”

    "After struggling with OCD for so long, Ashleigh helped me regain control of my life. I no longer feel compelled to perform endless rituals, and I’ve gained confidence in all areas of my life. Ashleigh also supported me with exam anxiety, sleep difficulties, and worked with my parents to help me at school. Most importantly, she taught me how to become my own therapist, empowering me to manage any setbacks in the future. Ashleigh helped me and my parents more than I ever could imagine."

  • "Brad taught me practical techniques to manage my social anxiety"


    "As someone with ADHD, I found Brad’s approach incredibly supportive. Brad encouraged me to talk through my problems without pressure, allowing me to work through my thoughts, no matter how unclear they seemed to me. Brad taught me practical techniques to manage my social anxiety, but also gave me the space to lead my own therapy, guiding me towards important realisations. I can’t thank Brad enough for his help."

  • "It was a lightbulb moment to realise that my self-esteem issues weren’t my fault"


    "I spoke to Ashleigh about some extremely painful and personal issues from my childhood. She addressed my concerns with complete understanding, encouragement, and zero judgment. It was a lightbulb moment to realise that my self-esteem issues weren’t my fault, and that I had the power to change. Our online sessions felt like teamwork, with Ashleigh sharing her screen and collaborating with me to set tasks, expanding my 'toolbox' for managing my perfectionism and self-esteem. Thank you for everything!"

  • An ADHD assessment is a diagnostic assessment that looks at whether ADHD is present. A cognitive assessment measures skills such as memory, attention, reasoning and problem-solving to build a profile of your strengths and challenges. It does not diagnose ADHD, but it can help explain how you learn, work and manage daily life.

  • At Regal, ADHD assessments start from £950 and autism assessments start from £1,950. Autism assessments involve more clinical time, which is reflected in the fee. Our fees page sets out the cost of every assessment and therapy session, for adults and for children and young people.

We help with performance anxiety, competing under pressure, injury and setbacks, and the move away from elite sport, all with complete discretion. Contact us confidentially to talk through what you need.

  • The first step is an initial assessment with one of our clinicians. It is a chance to talk through what is happening, ask questions and agree the support that would help most. You can book online or contact our team, who will help you choose the right service.
