“I loved the Accelerate programme and it has had a positive impact in every area of my business. Furthermore it has given me a solid framework on which to build for the future. The personal and professional approach taken by Optimum in delivering the modules was truly exceptional and made the course enjoyable and highly relevant to my business.”

"I recently undertook the Accelerate Programme, supported by DLR LEO and provided by Optimum Training. Optimum went above and beyond, not only providing a great training course but also making it relevant to each and every one of our businesses. They used expert trainers and mentors to give us the best advice in areas as diverse as marketing, finance, innovation and management. Mary's mentoring has pushed me in new directions and my business has become more successful because of it. Thanks Mary and all at Optimum!"

Andrew Bloom, Director, Mint Sales & Marketing

"The Accelerate program was one of the most beneficial business programs I have participated in. As well as the fantastic training, the chance to follow up with a mentor one to one was fantastic.
Mary and Ronnie of Optimum are a super team and went above and beyond in every aspect of the course; from their wealth of knowledge, interest in each participant, to creating a very friendly culture to allow everyone to benefit 100% from the program.
The delivery of the training was fantastic and both they and their team were very inspiring.
I would give them 10/10 for all they did for each and every participant. Nothing was too much trouble for them or their team.
I am delighted to have had the opportunity to work with them and this will hopefully not be the last time!"

Andrew McCabe, AMC Marketing

"Perhaps the best takeaway of all was the interaction with the other business owners, an amazing group of people with great experience in so many fields. Our sessions became ways to brainstorm, ask for advice and overall enjoy the process of working hard on improving our own day to day activities.

I'd highly recommend attending Accelerate with Ronnie and Mary for anyone wanting to inject new energy into their business. We worked hard while still having fun, always reminding ourselves of why we were passionate enough about something to create a business around it in the first place."
