I was fortunate to have Damian O’Sullivan work as my Real Estate Agent. I was selling a property in St Kilda and chose to work with him after meeting with several different agents. I chose Damian as I felt comfortable and confident in his abilities right from our very first meeting. His level of professionalism was outstanding. However, just as important to me as a vendor was his empathy and desire to get the best outcome for me. Open for inspections were run smoothly and his follow up with prospective purchasers went above and beyond what I expected. The eventual purchaser had attended several of the opens but was unsure whether they would attend the auction. Damian’s professional approach and regular contact led them to attend the auction and they were the successful bidders on the day. Having attended many auctions I know the value of a good auctioneer. Damian’s auctioneering skills are excellent. He not only promoted the benefits of the property but also the surrounding area. This was done in an engaging way without going “over the top”. In summary I can’t fault Damian’s work as my agent and will not hesitate to use him again in the future. Regards

We recently had the pleasure of dealing with Damian O’Sullivan who successfully marketed and auctioned our home in Richmond. Having spoken with several agents, we appointed Damian to represent us such was his professionalism and experience in the industry. Our decision was well and truly justified on auction day. Damian auctioneering skills and advice to us throughout the selling period were faultless. We were made to feel comfortable in every way in what otherwise can be a very stressful time for a vendor. We would happily use Damian again and again and have referred his services to many of our friends. Kind regards,

Darren – Richmond


To Whom It May Concern We recently appointed Damian O’Sullivan to sell our family home. We felt particularly comfortable doing so as he had sold several homes for my family before. This experience was not only financially rewarding given the sale price, but a very easy process such was the diligent and thorough way that Damian handled the sale. We were kept informed at every step and Damian’s advice was clearly designed to be in our best interests. He went over and above the call of duty from start to finish and we would have absolutely no hesitation in referring him to anyone considering selling. Yours Sincerely,

Justin – Port Phillip


This is my third transaction with Marshall White and again I wasn't disappointed! The service and overall experience was so professional. Damian kept me informed but more importantly as an overseas vendor, he was extremely prompt in his email correspondence and liaised in my time zone. His performance on the day as auctioneer was faultless and he was extremely accurate in his market and buyer analysis. His performance got me the price that I wanted and more of this I have no doubt! Could I please ask you to make it known to his "boss" that his performance was exemplary and that of his team a credit to Marshall White. Can I also thank you because it was the history we have and the respect I have for you made me go with Marshall White.

Firstly Damian Our sincere thanks for the way that you and Ben have handled the sale. And give our thanks to the rest of your team, particularly Jennifer. From the outset, you guys have ticked every box, including the demand from Catherine that you would continue to care!! Your auctioneering on the day Damian was great. You paid for our marketing campaign as you hoped you might – and more. We were all the more impressed after learning that you were then going on to sell a $3million plus property an hour later, but that obviously did not diminish in any way the effort that you guys put into clearing our property. Finally, I rang our tenant to advise the result about 2 hours later, only to find she had already been contacted by Marshall White, you even ticked that box. Needless to say, we will take every opportunity to recommend you guys to anyone looking for an agent, and we do talk to quite a few people in our daily rounds – at the shop, at the school and at the kindergarten. I hope it will bring you further dividends Thanks again. We are moving on. Best regards

John and Catherine - Port Phillip
