JD Davies
JD Davies The Partner / Manager M. 0433 427 503 Email

JD’s journey is a testament to his dynamic and multifaceted approach to sales and leasing. With a background that spans from the electrical field to the sports arena, JD has always been driven by a passion for excellence. His early days saw him leaving school for an electrical apprenticeship, while simultaneously playing premier grade rugby league for the Redcliffe Dolphins. His talent and dedication on the field sparked interest from the Brisbane Broncos, showcasing his commitment and team spirit.

However, it was the world of sales and real estate that ultimately captured JD’s ambition. Starting in front-line sales for a marketing company, he quickly learned that the essence of successful sales lies in understanding each client’s unique needs and desired outcomes. This insight has been the cornerstone of his approach to real estate, ensuring that every transaction is tailored to the client’s specific goals.

A chance encounter with Adam led to a pivotal turn in JD’s career, proving his worth and potential in the sales and leasing domain. Under the mentorship of Grant, a seasoned expert in sales and leasing, JD honed his skills and became a registered sales professional. His background as a second-rower in rugby league not only reflects his physical strength but also his ability to strategize, work in a team, and lead effectively.

Now, as a Partner here at The Commercial Guys and Manager for Sales and Leasing team, JD brings his diverse experience, unparalleled dedication, and innovative approach to the forefront. His leadership style is infused with the same energy and drive that marked his time in sports and sales, making him an invaluable asset to our team. Ready to lead the charge, JD is not just part of the team – he is a key player in driving our success forward.

Anna Grant
Anna Grant The Company Administrator P. 1300 477 180 Email

Anna has spent more time in the Real Estate industry than anyone else here. With a career that has placed her in both Residential and then onto Commercial for the last decade, Anna has performed most, if not all roles in an agency.

This makes Anna the perfect ‘All Rounder’ that she is and the areas she covers here at TCG can not be all listed.

It’s fair to say that Anna predominantly looks after administration across the board including Sales, Leasing, Asset Management, Company admin and keeping Grant and Adam organised.

Anna likes weird things, like woodchopping. It’s inexplicable to us and we just don’t understand it.

Chelsey Sellin
Chelsey Sellin Commercial Lease Asset Management P. 1300 477 180 Email

Chelsey is an awesome asset manager that comes to us from island paradise real estate land.

Working on a coastal island looking after a large mix of assets for lessors she has taken to real estate like a moth to a light ( I would have said ‘like a cat to a fur ball’ but we don’t want to imply “Cat Lady”)

In all seriousness, Chelsey is dynamic and energetic and is a constant source of vivaciousness and motivation for the team.

In her spare time, she enjoys beach trips, exploring and spontaneous adventures!

Chelsey became a first home owner this year and we all think it will be the first of many.
