Our Story

A practice grounded in relationships.

Loreena Gillon Chartered Accountants was established in 1997 and was renamed upon incorporation in 2017 as Arithmos Chartered Accountants. Led throughout this time by Director Loreena Gillon — a Fellow of Chartered Accountants Australia & New Zealand, Registered Tax Agent, Chartered Tax Advisor and Trust and Estate Practitioner.

We are deliberately niche. That means director-level attention, deep familiarity with your affairs, and advice that considers the full picture: your business, your entities, your superannuation and your estate — collaborating with your financial and legal advisors to achieve the optimal outcome.

Why Arithmos

The advantages of a niche firm

By not being growth driven we ensure the work stays personal and our standards high.

Director-level access

You deal directly with the firm's Director, a Fellow of Chartered Accountants Australia and New Zealand, supported by our team of professionals.

Deep specialisation & continuity you can trust

Income tax, SMSF, estate and succession expertise rarely found in a practice of our size.

The whole picture

Your family, business, entities, super and estate considered together — never in isolation.

Collaboration of the professions

To achieve optimum results requires liaison between legal, accounting, financial advisory and income tax expertise.

Our People

A steady team who knows you

Many accounting firms see a great deal of staff turnover. We don't. Most of our team stays for five to ten years — and Deborah Scuderi has been with the practice for over twenty-two years. When you call Arithmos, you reach people who already know your affairs.
