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.

Jessye Gelder

Administrative Assistant-Greven & Co

I work at Greven & Co part-time as an Administrative Assistant, while I complete my Certificate 3 in Business Administration at TAFE.

I am artist in my spare time, specialising in ceramics and analogue photography. I enjoy the meditative process of hand building pots and throwing on the wheel. The slow process of ceramics enables discoveries into the ways that ceramics and photography can intersect to create experimental cameras and images.

To relax I enjoy Pilates and yoga, walking, listening to podcasts and watching TV.
