Meet The Team


Cathrine G. Greven


Accountant & Financial Planner

I have worked in the accounting profession in Adelaide since 1985. I initially worked with other accounting companies before forming Greven & Co in 1993. From 1996 I saw the urgency to be educated and trained in financial services, so as to provide my clients with professional and accurate financial advice pertaining to not only their personal lives, but also to capture their business interests in that advice

I have obtained valuable professional experience both in my own right and by working with recognised experts in their fields to provide a reliable reference base for the benefit of my clients.

My qualifications are:
Fellow of the National Institute of Accountants
Graduate Diploma in Professional Accounting
Business Certificate in Accounting
Registered Tax Agent
Diploma in Financial Advising
Estate Planning

In my downtime, I enjoy painting (acrylic's and watercolours) – some of my works are hanging in my office, reading a variety of books from thrillers to self-improvement. I love to get outdoors and walk my two dogs, George & Chloe whenever I can, I practice Pilates, I also enjoy tending to my garden along with going out with family & friends for dinner and or a movie. I also take time out to travel (short and long holidays) as I believe you have to recharge your batteries in order to provide my clients with the best service I can.

Zak Mildren

Junior Paraplanner-Greven Financial Services

I've spent the past 7 years on and off with Greven & Co as a Receptionist/Administrative Assistant while I completed my studies at the University of South Australia, gaining a degree in Bachelor of Business Management at the end of 2016.

I joined Greven & Co as a Junior Paraplanner in the middle of 2017, and I'm studying for a Diploma of Finance online at the same time.

I enjoy staying fit and active through sport, mainly Soccer where I play for the Pembroke Old Scholar Soccer Club (POSSC) as well as participating in indoor soccer competitions weekly. At POSSC I'm also the Club's Squad's Manager (since 2016), a General Committee Member (since 2015) and on the Coach's Selection Committee (since 2016).

When I'm not running around the soccer pitch or at work, I enjoy spending time with friends, playing strategy computer games and watching TV series at home on the sofa.

Kiky Aritya

Accountant-Greven Accounting Services

I completed my Bachelor degree in Psychology in Indonesia, before migrating to Austarlia in 2014.

I have worked in various accounting positions such as accounts payable and administration and junior accountant before working as a tax accountant. I am an associate member of CPA and currently studying towards my CPA qualifications. My main interests are tax planning and accounting.

I joined Greven & Co in November 2020.

I enjoy exercising regularly, mainly weight trainings, with my boyfriend at our home gym. I find that weight trainings combined with eating healthy help with my physical and mental well being. In my spare time, I like to play video games on my PC/PS4 either single or multiplayer. Being a curious person, I also enjoy culinary adventure, either going out to have meals or cooking experimental food with different ingredients at home.
