After a distinguished career in high-end hospitality holding executive positions at The Regent Sydney, The Regent Melbourne, and in the meetings industry at places like the Melbourne Convention Exhibition Centre, Petrina now has a private consulting business and also is the Head of Admissions for the School of Thinking.
In February 2017, Petrina was awarded a Doctor of Lateral Thinking Honoris Causa degree by the School of Thinking. Her citation read,
… in recognition of her foundational assistance during the establishment of the School in Australia in 1988 and her continued support, innovation and development over thirty years.
During her long association with SOT Dr Gillespie has led a number of initiatives. She hosted a special Melbourne On the Move banquet for community leaders and VIPs to introduce the School of Thinking Principal on his return to Australia. She hosted the Food For Thought Luncheons in the 1990s and also hosted the Australian Thinker of the Year award receptions in the 2000s. She was Managing Director of SOT.
Petrina epitomises the style and grace of the no fuss, can-do attitude that we would expect from lateral thinkers of the highest order.
