Twenty years on. Garry still mountaineers between EOFYs.
After a level crossing accident in his twenties and the rehabilitation that followed, Garry Mueller retrained as an accountant. Two years later he began managing Sharp as Tax, and he has been here for twenty continuous years.
Off the clock, Garry has completed four of the Seven Summits, plus long-distance trekking, paragliding, sailing, scuba diving, and a quiet obsession with old cars and motorbikes. The Hills suit him.
Appointments with Garry are arranged through our receptionist. Call (08) 8391 6591.
Twenty years of trust, in the words of the Hills.
We don't write our own testimonials. The honest version of our reputation lives on Google, written by our actual clients.
