About Tristan
I bring a strong customer service background in both retail and hospitality to the hustle and bustle of real estate. I am a passionate, determined person who always puts my best foot forward in every situation that comes at me. The constantly changing, fast-paced environment that characterises real estate drives me to improve my efficiency, communication, persistence and meticulosity in the field. I really enjoy meeting new people and having conversations about anything real estate (or anything sports related!). My specialties in sales come down to my keen interest in analytics as well as a passion to help serve the community in the best way I can. I love to keep an eye on the property market to analyse current trends as well as look at all the phenomenal homes there are out there!

Wouldn’t use anyone else!

I don’t tend to do reviews but I think Adrian and his team at One Agency deserve recognition for their help and support. Adrian knows the area exceptionally well and helped us throughout our journey finding a new home. If we ever come to sell (hopefully not!) then I know who I will be contacting. You’d be silly not to use him and the team! Very grateful for all the support and helped us get the dream home we’ve wanted for many years.

Do your research!

Went with Adrian after reading multiple reviews and seeing the results his listing were receiving. I was incredibly disappointed when he palmed us of to his rookie employee who was incredibly inexperienced. When I went to meet with him asking what his role had been he felt the need to mansplain realestate to me and half apologised saying he’d been on holiday and would be at the next open house… he was not. The decision to go with Adrian cost my family over $40,000 and yes I’m adjusting for the current market. Incredibly disappointed with him and One Agency.

Exceptional service

I highly recommend Adrian and Tristan and One agency. They went above and beyound to not only sell our house in under a week at an exceptional price but went out of there way to help secure the property we were purchasing. They anticipated everything we needed and had it covered. They were upfront and honest in all their communications and readily available at all times. They are not only exceptional at what they do but also amazing human beings.

Stress Free and Exceptional Performance

Adrian & The OneAgency Team have exceptional insight into the real estate market in Melbourne’s North west corridor. As a boutique developer you look for a team that can not only develop a sales strategy but have values that align and deliver results. The Groves development was 90% sold in 4 weeks which given the current market is exceptional. Thank you Adrian, Tristan, Buki & Tayla we look forward to the next project!

Great operator

Tristan from the moment we met him was polite and punctual. Any thing we asked he got onto straight away. I couldn’t recommend him more highly.
