Team

Alistair Holmes, Director

Driven, tenacious and passionate about construction, Alistair studied Construction Management at RMIT and worked as a qualified carpenter before graduating to roles as project manager and contracts administrator for some of Victoria’s premier tier-two builders.

Since founding Sinjen with business partner Tim in 2011 Alistair has continued to confirm his reputation for being a skilled and knowledgeable builder and project manager, as well as establishing a brand that is now well recognised within the industry for being synonymous with quality and integrity.

While he is passionate about his work, Alistair’s most rewarding project is his family - wife Heidi and their two children.  In his down time he enjoys yachting and is never more at home than when he’s drenching sheep and raking hay at his family farm in North East Victoria.

Tim Nathan, Director

Beginning his construction career in 2003 as a builder’s labourer, Tim completed a carpentry apprenticeship in 2008 before working as a sub-contractor to a number of registered builders across Melbourne. Keen to put his extensive management and trade skills to work, Tim established Sinjen with Alistair in 2011. Since then he has overseen the successful delivery of more than 70 residential, multi-residential and commercial projects.

With an encyclopaedic knowledge of building codes, strong communication skills and a keen eye for design, Tim’s 14 years of construction experience is complemented by a Bachelor of Graphic Design from RMIT.

When he’s not hard at work Tim loves to travel with his wife Ida and their two children, Amalia and Larry.

Displaying an unabashed enthusiasm for life, she balances out the work-day week with regular exercise, cooking (her gravy is next level), collecting and restoring mid-century furniture and given the chance, camping, ocean swimming and overseas travel. Lauren cites buying her first property and holidaying in Iceland as recent life highlights, with camping on the African savannah and caging diving amongst sharks next up on the bucket list.

A family man with a yen for, quote, “anything with wheels”, Rohan values time spent camping and travelling, loves a beer and Indian food, is a keen photographer and, much like RoboCop, is partially made of titanium.

Sherry Woo, Estimator

With a degree in Quantity Surveying, Sherry has more than eight years of experience working with builders and consultancy on a range of different projects. She is excited to now be segueing from a high-volume and mass building environment to Sinjen’s premium architectural projects.

Relentlessly on-task through the working week, in her downtime Sherry likes to unwind and escape into her own world. Unimpressed by flowers or diamonds and with a strong aversion to the colour pink, we’re yet to uncover what guilty pleasures hold the key to Sherry’s heart.
