Gwen is our office administrator extraordinaire! Gwen manages our front of house and co-ordinates our service department and warranty work.

Gwen and her family migrated from South Africa to Australia in 2016. Her many years of experience with global corporation, Grindrod Limited, in South Africa, has equipped her with enviable business acumen and administrative skills. Gwen has the colossal task of scheduling our tradesmen and ensuring their paperwork is always on time and accurate (anyone who has worked with tradesmen will understand that 'colossal' is not a hyperbole) .

Not only is Gwen a 'master of her trade', she is also extremely generous with her time and spends the majority of her 'leisure time' volunteering for PAWS Darwin as an event coordinator and foster carer to animals. In addition, Gwen also volunteers with Save the Children where she spends time with children and families requiring special attention.
When not donating her time, Gwen likes exploring the top end on long family drives and motorbike rides.



Chayanne joined the Johnny Cool team in 2019, initially as a casual admin assistant. Chayanne's speed and accuracy in data entry was unsurpassable and she was made a permanent member of the team in 2021. 

Having spent the first several years of her life in South Africa, Chayanne moved with her family to Australia in 2016 where she completed secondary school at Darwin High. 

Inititally after finishing high school Chayanne enrolled to complete a teaching degree, she quickly realised her passion was in construction and prjoect management and she is currently studying a Diploma of Project Management.

Chayanne is somewhat of a linguist and is enjoys learning the Korean language in her leisure time. 

We envisions big things for Chayanne and expect to see her running huge scale commercial projects before she's 21.
