SMARTADHD Assessment and Coaching in Kent

SMARTADHD offers DIVA-based ADHD assessments from £199 with a two-week turnaround, run from Ashford, Kent by qualified ADHD coach and assessor Trevor Twohig. The approach is holistic — pairing a structured assessment with coaching, clarity, changes to lifestyle, and expert advice on supplementation, nutrition, and wellness. Medication is available via a sister company on referral if needed.

What to Know Before Booking

Coach-led, not psychiatrist-led: Trevor is a qualified ADHD coach and assessor with 20 years of SEN and ADHD experience, not a psychiatrist or psychologist. Whether your NHS GP will accept the resulting assessment for shared-care prescribing varies — speak to your GP before booking.
Medication via sister company: SMARTADHD itself does not prescribe; medication can be arranged through an associated sister company on referral.
Holistic emphasis: The approach is built around supporting clients to achieve their goals naturally — through coaching, clarity, and sustainable lifestyle change.

It’s so good to talk to someone who really understands the issues. Trevor is a breath of fresh air as he speaks from his own experience as opposed to text books. He has helped me to understand and focus on the positives and strengths and to accept and allow for the differences. Highly recommended.

Trevor is one of the most gifted and kind ADHD coaches I have come across. He has started working with my son over the last few months, and the attention, commitment, and ability to create a meaningful relationship with him online is incredible. Trevor truly understands the mechanisms of coping strategies and ultimately matches them with real-life situations. He is a brilliant example of someone who is genuinely committed to helping others.

I had a great experience during my ADHD assessment with Trevor. He was kind, patient, and genuinely attentive throughout the process. He explained everything clearly, made me feel comfortable asking questions, and really took the time to understand my experiences. His supportive approach helped ease my nerves and made the entire assessment feel validating and thorough. I’m very grateful for his professionalism and care.

I really appreciate how easy it is to talk to Trevor. He gets ADHD in a very real, lived-experience way, and that made the assessment and follow-up conversations feel open, supportive, and actually useful. It helped me understand myself better and gave me practical ways to navigate things day to day. I’d absolutely recommend him.

Working with Trevor has been life-changing. He has helped me understand myself in ways I never had before. I’ve struggled for a long time with ADHD and the side effects of my medication, but I was always scared to step away from it because I didn’t know what life would look like without it. Trevor has been incredibly supportive and gentle in showing me that there are alternatives — and for the first time in years, I feel better, clearer, and more in control of my life. Trevor is one of the kindest, most caring people I’ve ever met. He creates a safe, comfortable space where it’s easy to talk about anything — no judgment, just genuine understanding. He’s helped me work through my feelings, rebuild my confidence and self-esteem, and I've started believing in myself again. For the first time in a long time, I’m actually excited about the future. I feel proud of how far I’ve already come and motivated to keep becoming the best version of myself. The difference Trevor has made in my life in such a short time is incredible, and I’m deeply grateful for his guidance and compassion. If you’re looking for someone who truly listens, understands, and empowers you to move forward, Trevor is the person to talk to.
