“We brought in the Holloway Zaiser Group to encourage and support our team almost one year ago. We have had such a positive experience working with Mario – he is very approachable, knowledgeable and understanding. He is practical - he focuses on our strengths as a team to lift up and encourage and breaks down our weaknesses to help us rebuild them with a stronger foundation. We find his expertise to be very vital in achieving our vision and building a strong internal team.”


“Dale, you handled yourself professionally and in a respectful manner yet brought some light-hearted humour to the table. Thanks.”


“Mario was very engaging, extremely knowledgeable on the subject matter and an overall fantastic instructor — would highly recommend this course to EVERYONE!”
