Every Company Has A Story. This Is Ours.


At Brennan IT, it's all about customer service.

Founded in 1997 by Dave Stevens, Brennan IT started in a loft in Balmain servicing the Australian mid-market. As a team of four tech experts and enthusiasts, they shared the same passion, drive and mindset as our clients. Working fast, proactively and strategically as trusted partners and advisors for our clients, we were early pioneers in Managed IT Support and Cloud Computing.  Until this day the story and the core value of exceptional customer service remains. That's why over 1000 of Australia's businesses and largest brands such as Local Government Super, Simon George & Sons, Guide Dogs, PCYC and Strandbags choose Brennan IT over other IT service providers.  It is also the reason why we rank No.1 Managed Services Provider in Australia for seven consecutive years and more importantly why we still have clients' who have been with us since we started in 1997.
