Tania joined the Ambrosiussen team in March of 2016. She completed her Bachelor of Commerce degree
majoring in Accounting and Finance at USQ Toowoomba. Following completion of her studies she
returned home to Roma to work in a public accounting firm for 7 years. From there she went onto running

2020 and then wants to move on to gaining his CPA accreditation.

Before moving to Ambrosiussen, Tom spent four years working in the civil construction industry where his
main duty was working in the finance sector. He has definitely brought some cheeky humour here to the
office at Ambrosiussen. Possibly something he picked up from his prior work environment?

Tom is an avid sports fan and spends most Friday nights cheering on the Brisbane Broncos or the early
hours of the morning barracking for Chelsea Football Club. When he isn’t watching sport he is around at
his mother’s getting his Tupperware containers restocked with baked goods, enjoying a few pints at his
local watering hole with his friends, keeping his girlfriend happy by taking her to the beach or out for food
and studying for exams.
