Better Skills. Better Performance. Better Results.

The instructor is the best I've come across.

I would highly recommend the course the company and definitely the instructor. He made every part of it so interesting.

We have used Gary a number of times for training. He is an excellent trainer, and interacts well with his trainees. Feedback on his performance is always excellent. He is extremely flexible in his arrangements with us. I have no hesitation in recommending Gary to any company who wishes to use his services.

Over the past 20+ years I have done many courses and I can honestly say this course was by far the best in all respects.Gary, the trainer was very clear, easy to understand and very professional dealing with questions and answers.Honestly speaking, when I knew I had to do this course I was a bit nervous, however within minutes Gary had changed the atmosphere in the room from nervous to relaxed, where I found it easier to concentrate and get the best out of the course.

Rape Crisis Network Ireland have contracted Gary to provide annual Excel training to Rape Crisis Centres for over five years. He has been fantastic to work with and provided excellent quality training that was customised exactly to our needs. We have received very positive feedback from all staff who participated in the training and have continued to avail of the training every year because of this. He provided a second to none post-training service replying promptly to any follow up queries. He is both highly professional and personable in his approach and we look forward to working with him for many years to come.

I thoroughly enjoyed this intermediate level Excel course - it was the best course that I have undertaken and would highly recommend DTI for anyone looking to improve their understanding and general usage of Excel. Thank you Gary!
