In just two hours of hypnotherapy

Rated 5 out of 5

In just two hours of hypnotherapy, I was able to significantly undo a phobia about public speaking that was holding back my career. I can now be relaxed even at a big presentational meeting.

How Hypnotherapy Can Help You Overcome Anxiety & Panic Attacks

Rated 5 out of 5

“I went to see Darren as I wanted to overcome a serious phobia of public speaking and general anxiety issues. For many years I felt that feeling scared of speaking in front of a crowd was holding me back from driving my business further. Before a speaking event, if I was brave enough to commit to it, I was in a sheer panic and felt as if my throat would swell up and I couldn’t bring out a word. My voice was always shaky and I could not concentrate on the subject I actually had to speak about, all I was concerned about was that I wanted to get through it as fast as possible. I know that there was no reason for me to feel that way and I really wanted to change this situation as it was very much affecting my self-esteem and confidence. I didn’t quite understand how hypnotherapy worked and if it would work at all. But I am now completely transformed and recommend everyone to try it. It took only about 4 sessions which have not only changed my work life but also my personal life for the better. I can now focus on what I actually want to say, rather than on worrying about having to face an audience. And not only that, I now actually look forward to being in front of people as it is my moment to shine. I only wish that I had taken this step much sooner. I can recommend working with Darren to anyone. It was one of the best things I have ever done for myself.”

I knew Darren would be a good fit for me when I read the many ‘efficient’ written in his reviews

Rated 5 out of 5

I knew Darren would be a good fit for me when I read the many ‘efficient’ written in his reviews. I think when choosing a therapist, it’s important to know thyself, i.e. are you the type that need someone to listen to you ramble for months, to every little detail of your trauma, or are you the type that prefer a precision targeted approach, which zooms in on the roots of your addiction/neuroses/limiting beliefs and establish a healthier way of thinking and feeling. Many patients mention 3 sessions and it felt exactly right for me. I went in to fix my phone addiction but that was 80% alleviated after just the first session, there really is something magical that happens to the mind when in hypnosis. And unexpectedly we went onto tackle some of my other limiting beliefs which felt like a bonus achievement. Darren has a very calming and empathetic presence. He was also very professional and effective during some of the more intense moments. I have already encouraged many other friends to work with him. The Harmony App is a very generous offer of continuous support.

The sessions I did with Darren helped me to prepare for the exam day in a calm and confident manner

Rated 5 out of 5

I visited Darren when I was going through a tough phase in my career as a medical professional. I was undertaking a membership exam which I had failed twice before and this was leading to a lot of anxiety and low self esteem during the build up to the exam. The sessions I did with Darren helped me to prepare for the exam day in a calm and confident manner and I have now passed the exam and have the Membership degree. I sincerely recommend his hypnotherapy sessions and the hypnotherapy meditations that he provides.

Rated 5 out of 5

Following the recommendation from another friend who is nearly 1 year smoke free, I have seen Darren over 2 months ago and have not touched tobacco or even had any serious craving (strange!). I was impressed by how engaged & personable Darren was with me and his efficient approach really helped me to consolidate my resolve. Totally recommend when you are ready to take control over your life :)

Rated 5 out of 5

Darren was great and over 3 sessions helped me to start the process of changing my thought patterns. The app is brilliant and access to that alone is amazing and well worth while, I use it daily and it has a huge amount of recordings.

I can’t recommend Darren and his app highly enough.

Rated 5 out of 5

I can’t recommend Darren and his app highly enough. I went to him to give up smoking and was immediately surprised by how comfortable and relaxed he made me feel. He’s empathetic and helped me address long-term issues, leaving me with greater clarity, confidence, and a sense of safety. I genuinely feel enhanced. The app itself is a beautiful experience — some audios helped me gain deep personal insight and better ways to face challenges, while others feel like pure leisure, guiding me through vivid, imaginative journeys. I’ve had the best sleep ever since.

Its been approximately 3 months since the 3 session i did with Darren to boost my confidence

Rated 5 out of 5

Its been approximately 3 months since the 3 session i did with Darren to boost my confidence. I can say that I am experiencing a transformation of sorts and my confidence levels are now increasing noticeably. I feel a lot more capable dealing with my life and responsibilities and i have a feeling this is just the beginning of my journey. Darren was lovely to work with both online and face to face ( I did both). Highly recommended from me.

Darren helped me get to the root of the issues I was facing

Rated 5 out of 5

I went into hypnotherapy with Darren not knowing much about it, expecting it to be similar to traditional counselling. I was pleasantly surprised to find it far more effective. Darren helped me get to the root of the issues I was facing, align myself with them, and work through them in a way that left me feeling lighter, more confident, and genuinely changed for the better. I originally sought his help for a fear of choking, which developed after a past incident. Not only did Darren help me overcome this fear, but he also addressed underlying anxiety that I hadn’t realised was connected to it. His approach was professional, supportive, and deeply insightful. I’m truly grateful for the progress I’ve made and would highly recommend Darren to anyone looking for meaningful, lasting change. I have also been using his app daily, and have found this life changing too.

I stopped smoking after just one session…

Rated 5 out of 5

“I stopped smoking after just one session with Darren. I’m delighted to say that after 25 years of smoking I have now been a non-smoker for the past 15 months… I left that session absolutely cured of my addiction.”

Medicine Today Stop Smoking & General Hypnosis Article

Rated 5 out of 5

I came out of Hypnosis feeling sleepy but clear-headed – entirely free, both of the anxiety that had pervaded the last three or four days, and of any but the most distant desire to have a cigarette. And the feeling continued through working days, visits to pubs and restaurants. I wasn’t smoking and I didn’t mind a bit…..

I saw Darren to help me quit smoking..

Rated 5 out of 5

“I found Darren after a lot searching on line and checking reviews. And I can say that effort payed off. I was having problems with blushing as well as communicating with clients and with large groups of people in social situations, and after a few sessions it was noticed by myself and others that there had been a significant change in how I interacted with others. My confidence has increased and I feel comfortable. Thank you Darren.”
