Rossignol Advisory revisits 30+ years of CCH content

A Career Built on Expertise. Backed by Trusted Knowledge.

How Glenn Nightingale of Rossignol Advisory has relied on CCH iKnowConnect throughout every stage of his 30+ year professional journey

Over the course of a career spanning more than three decades, Glenn Nightingale has worked across some of New Zealand's leading accounting and advisory firms, including Deloitte, Bowden Impey & Sage, PwC, Staples Rodway, Burns McCurrach and Findex, before establishing his own practice, Rossignol Advisory. Throughout that journey, from accountant to partner, director, business owner and specialist advisor, one thing has remained remarkably consistent: he’s always had access to trusted knowledge.

As the profession has evolved, Glenn has continued to rely on Wolters Kluwer solutions to help him develop expertise, stay current and deliver advice his clients can trust.

Today, he provides consulting, restructuring, valuation and litigation support services, drawing on decades of experience built on a foundation of continuous learning and reliable information.

As you get more senior, clients come to you for answers. You don't have to have instant answers, but you do have to have the ability to provide information you’re nearly 100% sure on.
Glen Nightingale, Director, Rossignol Advisory Limited 

For Glenn, that confidence starts by building knowledge and by being able to trust the information behind every decision.

Building expertise through continuous learning

Throughout his career, Glenn has maintained a strong focus on professional development.

As legislation changes, regulations evolve and client expectations shift, staying current requires an ongoing commitment to learning. Beyond keeping up with industry developments, continuous education has helped Glenn strengthen his technical capabilities and maintain the confidence needed to advise clients effectively.

CCH Learning has played an important role in helping him do this.

Through training courses, webinars and ongoing professional education, Glenn has been able to continually refresh his knowledge and stay connected to the latest developments in the profession.

I've completed the CCH Learning online training courses many times over the years, just as refresher courses, and they've been really helpful.
Glen Nightingale, Director, Rossignol Advisory Limited 

For Glenn, professional learning isn't simply about earning CPD points. It's about building expertise that can be applied directly to client work.

Maintaining a strong foundation of knowledge

As Glenn's career progressed into partnership, business ownership and specialist advisory work, he recognised the best client outcomes come from maintaining a strong foundation of knowledge.

Rather than relying solely on external specialists, he believes advisors should develop their own understanding first, especially when dealing with complex tax and business issues.

"If you're going elsewhere for information, you won’t be able to keep your own tax knowledge up to date."

This is where CCH iKnowConnect has delivered lasting value.

Whether researching legislation, reviewing GST implications, understanding case law or validating a position before advising a client, the platform provides Glenn with quick access to trusted content authored and maintained by experts.

"When you need an answer, it's got the answer there for you."

For Glenn, access to trusted research is about more than efficiency. It's about building confidence in his own knowledge and ensuring the advice he gives clients is supported by expert sources.

Trusted information creates confidence

Across restructuring projects, litigation support matters and valuation engagements, tax considerations often play a critical role.

"There is tax in everything you do," Glenn explains. "So you need to be aware of it."

When evaluating complex issues, he values knowing the information he is relying on has already been carefully researched, validated and cross-referenced.

The answers I'm getting are validated. It's all drafted by tax experts and very well cross-referenced between legislation, case law and commentary.
Glen Nightingale, Director, Rossignol Advisory Limited 

That level of trust becomes particularly important when preparing advice that clients, business owners and other professional advisers will rely on.

For Glenn, CCH iKnowConnect provides both the confidence to validate his thinking and the foundation to engage specialist advisers when required.

"It gives you a good base to go externally to specialist tax firms. You know the questions to ask."

A relationship built on trust

Few professionals can point to a solution that has supported them throughout almost every stage of their career.

For Glenn, Wolters Kluwer CCH has been a trusted resource from his earliest years in the profession through to partnership, business ownership and independent consulting. Throughout that journey, CCH Learning has helped him continually build expertise, while CCH iKnowConnect has helped him put that expertise into practice with confidence.

"It has been a long career and a long relationship with Wolters Kluwer."

More than three decades after entering the profession, Glenn still believes the principles behind great client service remain the same: keep learning, know your stuff and provide advice people can trust. That is why he feels trusted information remains so important.

I know I can ask questions, get the right answers and find the information I need. There's never been a case where I've had to doubt the information.
Glen Nightingale, Director, Rossignol Advisory Limited 
From developing his knowledge as a young accountant to advising clients as a business owner and specialist consultant, trusted knowledge has been a constant throughout Glenn's career. Through CCH Learning and CCH iKnowConnect, he has been able to strengthen his expertise, validate his advice and deliver the confidence clients expect from a trusted advisor.
