Gorgeous premises and lovely, knowledgeable team. I really enjoyed my course (Adobe Firefly) - the tutor was friendly and professional and happy to answer any questions and tailor the course (I was the only student so had my own private session). The class room and the whole building is really well done, modern, clean and professional space that reflects the overall approach. They have fast and modern machines available to use or you can use your own devices. Highly recommended.

Quadrotech — June 2026

Fantastic and super valuable training! Fantastic and super valuable training! Tony shaped the training fully to our needs, adapted, accelerated and deep diving when needed. I learned so much these past days with tangible examples Tony provided.

Adobe — June 2026

The trainer, Lee, was excellent. He rattled through the key elements of Premiere Pro while keeping the course interactive and engaging. The small sessions made it easy to get 1:1 support or clarifications. The pleasant and well equipped office is well situated in Kensal Rise, so easy to find and get to. I learnt a alot - and now feel up to date with latest Premiere Pro options and AI integrations.

Hi Brook, Sorry for the delay - I was on AL yesterday! The training was great, thank you. Tony was very thorough with everything and I definitely left with some new knowledge and skills. I'll leave a review later today. Thanks for sending the materials across. Have a lovely rest of your day!

I wish all training courses were run this well!

RPS Design — June 2026

The Design and Development areas of Clarks shoes has been using Transmedia as a training partner for eight years now, mainly in the 'creative' Adobe applications - Photoshop, Illustrator, InDesign and Premiere. In that time we have built an excellent working relationship with the management and admin teams and several of their core trainers. This has had a major influence in raising the skill levels and quality of our artwork across our design teams- recently extending across the Atlantic, delivering training to our US based designers. Staying with Transmedia has given us continuity and enabled the trainers to really come to understand what Clarks require and thus able to deliver real value for money. The staff are always friendly and a pleasure to deal with - whilst being efficient and professional throughout. Nothing is ever too much trouble. I really can't recommend Transmedia highly enough.

Clarks International — June 2026

The course was excellent - exactly to my company's needs. All questions were answered and concepts explained very clearly.

Hannah Griffiths — June 2026

First class - The trainer was extremely knowledgeable and answered all our questions.

MOD — June 2026

The course itself was really informative and trainer was excellent. Poor communication and organisation between transmedia and QA meant my course was cancelled twice. I hope you improve this relationship. To be honest I would prefer to book direct through you next time, avoiding QA.

Deborah M — June 2026

The session on the 25th was brilliant, thank you. The SE's found it very useful and loved Tony's tips and tricks to help us update our prototypes quickly.

Salesforce — May 2026

I thought the course and the location were perfect

Wonderful trainer Lisa - fun, friendly, informative and comprehensive course! Thank you very much indeed.

Structural Soils Ltd — May 2026

I have taken part in several Transmedia courses and will likely take part in a few more. From start booking to training Transmedia are brilliant to work with. Happy to answer all questions ahead of booking to help make sure you're on the right course (thank you Jo). The training itself is very thorough and the instructor, (Lee in my case) was happy to stop and go through any parts that were a struggle during the course.

Reach plc — May 2026

Very much appreciated and enjoyed the introductory course. It was very in-depth and Tony did a fantastic job of covering each individual section of Figma in great detail; no stone was left unturned. Tony is clearly passionate about what he does, which made the course that much more enjoyable and valuable. Looking forward to the advanced course next month - eager to continue learning more from him.

Wren Kitchens — May 2026
