This fully licensed veterinary hospital was established in 1980 by David and Peter Mylonas with the aim to provide quality care at affordable prices for the people of Blacktown. Our partner, Tony O’Callaghan, joined our team in 1985 from Queensland and has proven very popular with our clients since his arrival with his friendly outlook and great diagnostic and surgical skills. David and Peter and

our long term associate, Ben Hawtrey, all grew up and were educated in Seven Hills so they have an understanding of the local area and that means they can empathise with the needs and requirements of our clients and patients. We offer our Clients and Patients the advantage of being a very EXPERIENCED TEAM of Companion Animal Veterinary Clinicians and Surgeons in the Blacktown area with all of our Vets having 20-30 years of practice in Veterinary Care. This means we can provide the best in diagnosis, treatment and care with great outcomes in the most efficient, timely and cost effective manner without guesswork and over-servicing. We are able to offer a range of treatment options and cost options to suit the individual client and patient as required. As a fully licensed veterinary hospital we are able to perform all forms of major surgery on Companion Animals. We take pride in the wide range and quality of the surgical procedures we perform and we welcome second opinions and cost enquiries. Thank-you for considering entrusting your beloved pet to our care. We invite and welcome inspection of our modern Hospital facilities which includes reverse cycle air conditioning and fully lined walls and runs in animal care areas.
