Greg and the OPES team were wonderful to be involved with from our purchasing perspective. We genuinely appreciated the sincere, transparent communication. We were continually kept in the loop in all aspects of the purchase of our new home. To us, communication is key, and we never felt for a moment that we weren't being kept updated. The time taken, and genuine interest to understand what we were looking for in our new family home was second to none, and all of our questions, no matter how trivial, were answered with care and respect. Thank you for helping us secure our family home.

Greg and Alex worked tirelessly on the sale of our home in a tough market. He was always responsive and is a true professional. Greg is honest, considerate and understanding. This is the second time we have used him for the sale of our home, that should speak to the faith we have in his ability. Thank you again.

Greg provided exemplary service and was extremely accomodating to changing timelines. Pleasure to work with!

Greg is a true professional and extremely good communicator; I chose Greg for exactly those two reasons. Throughout the sale of my house, Greg was always punctual with feedback, updates and advice. He went the extra mile even at the start to make things easier and quicker. Most of all, Greg’s integrity is something I truly value and is rare to find. I highly recommend Greg for the sale of your house.

Greg is a sales executive that every company would love to employ. His research and knowledge gives him the ability to confidently tackle any job at hand. Very rarely do you find an agent that carefully manages the sellers and buyers needs. Greg has exceeded our expectations in a tough market.

Greg helps us purchase our dream home in Castle Hill. He is so helpful, transparent and most importantly he is Trustworthy and Reliable. He helps us seize the great property in just 3 days (2 inspections, one on night, one on morning). And during the opening inspection, he is extremely patient and we are so grateful for his honest suggestions. Is absolutely wonderful to work with Greg. Absolutely recommend!

Wow Greg and his team made selling my property stress free, The professionalism and communication is second to none Greg was able to achieve more than other agents appraise. Greg and his team are professional and personal. They were extremely helpful, open, transparent, and reliable through the whole sales process, he genuinely cared about us and achieving the best possible outcome, he understood our needs from the very first open day even went above and beyond a sales agents duties to help us sell the property from North Kellyville. Greg and his team offer hyper communication so even though they were always available to answer questions I never felt the need to call Greg as I didn’t need to due to Greg being proactive in providing regular and detailed updates. I never felt in the dark, uncertain or unsure about how best to move forwards with the sale of my property. Greg is absolutely wonderful to work with. It’s like having a friend on the “inside” that is working for you. He really cares about his clients as well as the community and the neighbourhood his services. I feel lucky to have had Greg and his team in my corner when it came to the sale of my property. I cannot recommend Greg and his team enough!
