Description
Mellor Olsson are a proudly South Australian owned and operated firm providing legal services throughout the state. Our origins date back to the 1800’s, although the current name was first used in 1992 following the merger of two firms, “Mellors” and “Olssons”.
What has been consistent throughout our existence are the fundamental principles of our business: a strong commitment to South Australia, a core focus on servicing clients in regional areas and a dedication to providing the highest quality legal advice with personalised service.
We are one of the largest full service legal firms operating in South Australia. We provide employment for more than 90 people across a range of legal, administrative and business support roles.
We have a head office based in the Adelaide CBD and permanently staffed regional offices in Clare and Port Lincoln. We also regularly visit regional towns including Balaklava, Burra, Bordertown, Cleve, Kadina, Keith, Kimba, McLaren Vale, Nuriootpa, Riverton, Streaky Bay and Wudinna, to provide legal services to local residents
What really sets us apart in a tight and over-serviced legal market is our philosophy of always making a real difference to our clients. This includes:
- Access to Partners
- Friendly client service
- Fast and efficient project turnaround
- Knowledgeable lawyers with positive attitudes
- Practical legal advice free of jargon
- A commitment to metropolitan and regional SA
