As the newest member of Kristallis accounting—and the third generation in the family business—I balance my part-time role at the firm with university life. I bring a fresh perspective and plenty of enthusiasm to the team.

With my energy, curiosity, and drive, I’m excited to help shape the future of Kristallis accounting—proving that the next generation is ready to bring some spark to the numbers.

Andrew Kristallis runs a superb accounting business: - highly knowledgeable and professional - excellent use of technology to keep costs down while maximising service levels - a great team leader - all the Kristallis staff are there for the customer. Having used Kristallis extensively for personal, company, trust, and self-managed superannuation, I give them a 10 out of 10.
I have been with Andrew and his team for over 10 years. Great knowledge and experience. I would highly recommend him and his team.

Andrew and the team at Kristallis were instrumental in the complete startup and ongoing accountancy of my successful small business. Their knowledge and service gave me peace of mind to concentrate on other aspects of my business and also gave me guidance when required. I highly recommend Kristallis to anyone in a heartbeat!

Evan
I have found Andrew and his team to be very professional in all the time I have been dealing with them. Having a team around them of Financial Planner, Conveyancer, Bookkeeping services and Mortgage Broking is also a big plus. Highly recommended.

Con Kristallis has taken care of me and my company for the past 35 odd years... I am not an easy client but his patience and kindness is boundless and I am happy to say he has passed these qualities on to his sons, in particular Andrew Kristallis, who has modernised the accounting firm with integrity and friendship... You know this is true as they have the most loyal and kind employees and have retained the personal touch and the ideals of 'quality' which is rare in this increasingly digital and impersonal world. Bravo!
