Con Kristallis

Founder, JP, FCPA, FCA

  • I’m a proud 50-year member of Chartered Accountants Australia and New Zealand (CAANZ). With a strong background in finance, I’ve dedicated my career to providing trusted, professional accounting services.

  • In 1977, I founded Kristallis accounting with a vision to serve Sydney’s Inner West community. Over the years, I built the firm from the ground up, becoming a trusted advisor to families and businesses across generations.

  • What I’ve always valued most is the trust and relationships formed with clients. For me, accounting has never been just about numbers—it’s about integrity, honesty, and helping people succeed.

  • Kristallis accounting is now a three-generation family practice. My son Andrew leads the firm as Managing Director, and my granddaughter Isabella has also joined part-time while studying a double degree at UNSW.

    Sandra

  • 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.

    Anthea

  • 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!
