Here at Calculated Consulting, our team have experienced every aspect of accountancy, servicing large corporations and not for profits through to owner-operator start-ups.

Accounting and Bookkeeping

After six years in the Australian corporate space, Celina developed her international experience by relocating to North America. There, she undertook studies at Harvard University before living and working in Vancouver, Canada for the next four years managing businesses, people and finances. Upon returning to Australia, Celina sought out the opportunity to connect and embrace a more holistic approach to business advisory services for SMEs.

Now, with a growing team, of bookkeepers, accountants and admin support, Celina is looking to help even more Australian clients achieve the professional success they’ve been working toward.

From Deloitte to Calculated Consulting: Celina Grech

Chartered Accountant and Firm Principal, Celina Grech, established Calculated Consulting in 2017 after discovering tradespeople in her area were experiencing a lack of approachable accounting and bookkeeping support.

Celina started her professional career as a trainee at accounting firm, Deloitte. Starting out in the Deloitte Private Division, Celina worked with businesspeople at all levels of management as well as high net-worth families and businesses. She then went on to work in the finance industry where she had the opportunity to expand her financial analysis skills and experience.

“How lucky am I to have been introduced to Celina through a mutual business contact! Celina was introduced to me at a point that my business needed a serious introduction of skill, experience, and can-do attitude.

She has also worked closely with me to start setting the future direction of the business which we are eagerly looking forward to progressing over the next few months. While our business relationship is only young, I feel certain that we will build a very strong long-term relationship that will be very beneficial to my business for many years.

Having access to Celina and what she brings to anything she does will be a large part of the future success of my business. If you are looking for a new accountant/bookkeeper with a can-do attitude and actually cares about your business, coupled with of the skills necessary to assist your business then do not hesitate to get in touch with her. You will not be disappointed.”
