Our History

O'Hara's Pharmacy is one of the oldest surviving pharmacy in the Perth Hills. Originally opened by John O'Hara, the current pharmacy still stands on the same site. Graham and Matt McLachlan purchased the pharmacy in 2012 with Andrew Mason coming on board at the end of 2015.

We are passionate about the hills community and the relationships we have formed over the years. Helping people achieve their health goals is something we love doing and gives us a great amount of satisfaction.

Our Pharmacists

Almost as old as “the hills” pharmacist. I strive to make clients and staff happier when they leave the pharmacy than when they came into the pharmacy. I believe in building happy and healthy relationships with people. After years I still find community pharmacy rewarding and satisfying. 

A pharmacist who worked for me put a big poster up on the wall behind the till ”Our returns policy is that you return to us as often as possible”.  I liked that very much.

Owner / Pharmacist


I have been a pharmacist for over 12 years working in various community pharmacies in Perth, regional W.A., the UK and for the past 6 years at Haynes St Pharmacy and O'Hara's Pharmacy in Kalamunda.

I enjoy helping people with all aspects of medication management and have an interest in compounding personalised medicines for patients.

Outside of work I enjoy watching cricket and Aussie rules. I love my running, and taking advantage of all the trails the hills have to offer when I can. I love talking about all 3 if you want to pop in for a chat.

Owner / Pharmacist


I have been working in community pharmacies for over 13 years. With an extensive knowledge and experience in retail pharmacy and an interest in integrative medicine, I have been serving the community in the Kalamunda area for 12 years as managing partner at Haynes St Pharmacy Kalamunda and O’haras Pharmacy.

When not at work, I enjoy spending time relaxing with my wife and children. I also like to keep active by cycling, and you might catch me on my bike in the hills on the weekends.

Owner / Pharmacist


I have been a Pharmacist for 12 years and in that time have worked in many different parts of Perth and rural Western Australia (and Kalamunda is by far my favourite!) No matter the location, I have always had a customer first attitude and strive to provide the best health care solution to any issue a customer presents with. I am especially interested in the fields of acute/chronic Pain Management which is unfortunately becoming a more prevalent issue in modern society as well as helping people adhere to and understand their medication regimens no matter how complex.

Away from work, myself and my wife have just had our first child in September 2018 which has been an amazing experience. When people say your life is about to change forever I now understand what they mean! It has certainly given me a new perspective on life, both at work and at home.

I am a member of the West Coast Eagles and love getting to as many games as possible during the season and I'm always keen for a chat about AFL or for that matter any sport in general!
