About Us

Monaghan McLean & Co was established in 1987 in the south eastern suburbs of Melbourne to service the accounting and taxation needs of local small business owners.

The foundation partners were Alan Monaghan and David McLean.

Three decades later the practice has grown significantly and built a reputation for delivering quality service and advice to small and medium sized businesses. While the business name changed to Upside Accounting in 2016 and the personnel has changed over the years, our commitment to provide exceptional value and service remains a constant.

Since the firm was established 30 years ago we have been committed to providing an ‘old fashioned’ service where the partners regularly visit the premises of clients to get a better understanding of their business, their products, their services and their staff. We have evolved from being a traditional tax and accounting practice to a full financial services firm providing business owners with more than just tax returns and compliance. In fact, our positioning statement of ‘Helping Your Business Achieve Amazing Results’ really captures our mission.

Alan Monaghan retired in 2003 while David McLean retired in 2008 at which time Adam Wilson took over the practice. The current team members take great pride in the history of the firm and continue to strive to deliver outstanding and proactive service. 

To help you achieve amazing results in your business we provide you with strategies to grow your revenue, profits and business. We also help you create wealth using tax effective strategies such as negative gearing and superannuation plus we also work to protect your assets and minimising your exposure to tax when you sell your business.
