Who we are

Real-world operational experience, applied to your challenge

Riverglen Consulting brings more than 25 years of senior leadership across local government, water services, energy and telecommunications — turning complex, fast-moving environments into clear structure and confident delivery.

Deep industry experience. Direct leadership of water, wastewater and stormwater service delivery, with earlier senior roles spanning three waters management, district facilities and utilities.

A proven track record. Delivered major infrastructure projects, procured and negotiated significant contracts, managed crisis situations, realised meaningful cost savings, and led successful transformation programmes — all underpinned by strong stakeholder engagement.
