I've worked with ROAST for about 6 years now, and have found them to be everything you'd want in an agency. The team are so knowledgeable and brilliant at their jobs, and every single person has been so lovely to deal with.I cannot recommend ROAST enough.

Michael Olu's Review Sourced from Google
I enjoyed the course and learned a lot from it. The academy is well organised and focused on practical disciplines such as SEO, PPC, Programmatic, Mobile and Display. I particularly enjoyed the bits of psychological research and discussions shared in our sessions. I would definitely recommend to those starting out and have interest in digital marketing. Well done to everyone involved at the course. And a BiG thank you to the entire TIPi team!
