“I commend JS Mueller & Co Strata Lawyers and the work that they did for me – preparing bylaws for renovations to our apartment. Being the former Mayor of North Sydney, I’m rather fussy when it comes to professional service, detail and adhering to agreed timelines! JS Mueller & Co Strata Lawyers didn’t let me down and exceeded my expectations on every level. A big shout out to Nasreen who assisted me every step of the way & worked to tight timelines."

Jilly Gibson Former Mayor North Sydney

I have used Adrian Mueller and the team at JS Mueller & Co Lawyers for strata law matters over many years. The team at Muellers consistently provide prompt, excellent service and terrific advice across all areas of strata law. They are clearly one of the leaders in the field of strata law and I have no hesitation in recommending the team at JS Mueller & Co Lawyers. And keep up the good work!”
