From trouble sleeping to anxiety to depression, mental health problems can affect many of us in different ways. Mindler (previously ieso) therapists treat a range of common mental health symptoms.
What people say
We’ve helped thousands of people feel better. Here are their stories of recovery and growth.
Would definitely recommend
I felt comfortable taking with my therapist. The homework I had made sense, and it did help... and it continues to help. We explored my past, and I became more aware of my triggers and began to analyse my fears more productively.
Helped me understand how my brain was working
The weekly sessions were structured and focused. The exercises really helped me understand how my brain was working in a negative way. I was able to think through the sessions with no pressure.
Simple and easy to use
The weekly sessions were structured and focused. The exercises really helped me understand how my brain was working in a negative way. I was able to think through the sessions with no pressure.
I use what I have learned to help me navigate life every single day
CBT has helped me become much more self aware in many areas of my life, over and above the difficulty that prompted me to apply, so even though sessions have ended I use what I have learned to help me navigate life every single day. Do try this. It may not be for everyone but you may be surprised how much it can help you and even change your life!
I have learnt so much
I cannot praise Mindler highly enough... I have learnt so much and have many tools that I can now use to remind me of all I have learnt. You need to, and are expected to, put in effort to try and help yourself, along with so much help, empathy and kindness from your therapist.
After two or three sessions started to feel the benefit
Following instructions, I started exercises and after two or three sessions started to feel the benefit. All I can say is, give it a go, it can't make you feel worse only better.
Meet the therapists
Mindler (previously ieso) therapists are committed to a lifetime of learning about the techniques, tools and treatments that help people recover. We’re united by a passion for continually getting better, so we can help people get better.
Improving treatments.
Improving how the world sees mental health.
The brain is the least understood part of the body. Treatment of physical health problems is increasingly precise and sophisticated but the world knows less about what makes mental healthcare successful and why. At Mindler (previously ieso), we're bringing precision to mental healthcare using over 650,000 hours of de-identified therapy data, deep analysis and science, to bring you the therapy that’s likely to work best for you.
People often ask us...
It’s natural to have an interest in your treatment. People often want to know what we do, how it works and whether it will work for them. Here’s our take on some of the questions we often come across.
Once you have activated your account, you will receive an SMS with a link to select a session time that suits you, and to book your first session with your therapist. All future sessions after your initial one will be arranged and confirmed with your therapist via messaging in the therapy room. Nothing else will be required of you (other than to make a note in your own diary of the day and time agreed with your therapist). Your first session is usually a maximum of 10 working days from sign-up (though in very busy periods it can take a little longer).
You will meet your therapist online at a time that suits you, so you can attend treatment sessions from wherever you want. This means you won't have to travel, take time off work or explain your situation to your employer.
Mindler (previously ieso) doesn’t provide a pre-set number of sessions. We offer you the right number of sessions needed for your treatment. Practicing the CBT techniques, you will learn between therapy sessions will help you feel the benefit more quickly. But, as a rough guide, we can typically address mental health issues like anxiety and depression in 4-8 sessions.
As of August 2025, ieso is now Mindler Ltd, one of Europe’s leading digital psychology providers. We are committed to continuing to provide high quality mental health treatment. If you are receiving treatment from our team, your care stays the same, with no change to how you access the therapy room, or how you meet with your therapist. Our policies and procedures will also remain the same, click here to read.
After your therapy sessions have ended, you’ll be able to log in to the Mindler (previously ieso) site for 20 years after discharge, allowing you to access all of your sessions, messages and goals to remind yourself of the skills you’ve learnt. If you find yourself feeling worse again or experiencing new difficulties, you can go back and use this information. However, you are welcome to return to therapy if you are still struggling. *
*Provided you’re still registered with a GP in an area where we’re contracted by the NHS.
We totally understand that when you just want some help, completing questionnaires can be frustrating. We wish there was another effective way. Unfortunately, we can’t safely allocate you a clinician and start your treatment until all the assigned questionnaires are complete.
The questionnaires help your clinician understand you and your current state of mind. And they’ll help you to check your progress and flag up any problems. The NHS also requires everyone to complete these questionnaires. This is why, throughout your therapy, you'll be asked to complete the questionnaires before each session.
