Dean Mounsey

Country Manager, Australia

I'm surrounded by gifted people who do anything for each other - I mean anything. I find this very humbling. Two decades at Impact have taught me the value of compassion, loyalty, striving for excellence in everything you do and always getting back up when you fall down. This has helped me gently hold that most elusive of holy grails, true meaning at work. I love and am gratefully centred by my wonderful family.
