Client Testimonials

“Erin (OH NUMERO) made an immediate impact at Denison Gas. She was brought in to review our finance function, performance, and compliance framework, she quickly identified practical ways to strengthen how we operate.

She supported us through a major system transformation mid-financial year, seamlessly assisting the transition of our ERP, Payroll, and HR platforms. Erin was incredibly helpful and approachable for the finance team, providing support and clear direction throughout.

Her ability to combine technical depth with strategic perspective has added lasting value. Erin helped us implement industry best practices, improve our reporting, and tighten project cost control – all contributing to a stronger, more agile finance function at Denison Gas. Erin was also extremely supportive and hands-on with the finance team, providing clear guidance and fostering their development through the changes.”
