Hello! I am Mary-Thea Brosnan, owner of Kerry Kefir
I love the great outdoors, something I only discovered in my late 20’s. I love the mountains, I love the sea and I love everything about nature. I also love my dogs, Ben and Obie. Two beautiful golden retrievers with completely opposite personalities.
After 14 years living in Dublin, I moved home to Castleisland in Co. Kerry in October 2018 to start Kerry Kefir. I continued to work part-time as an Optometrist (I have a BSc in Optometry) before going full-time with Kerry Kefir in January 2020. I started the business in my parents’ kitchen but I soon moved to a converted truck container behind the house.
For the first year, I sold directly to customers in Castleisland but Kerry Kefir is now stocked in SuperValu stores and independent retailers around Kerry.
Having suffered from digestive issues for years, I was prescribed tablets to be taken before every meal for the rest of my life.
I spent years looking to help my symptoms through diet until a nutritionist advocated milk kefir, a fermented milk beverage packed full of beneficial bacteria and yeast for your gut health.
I sourced kefir grains and started making it myself. Within a week, the kefir milk had made a huge difference to my symptoms. I couldn’t believe it!
I noticed that none of the milk kefirs on the market were made in the traditional way using kefir grains but were instead using powdered, lab-manufactured cultures. So I decided to create a premium product using the living organisms to produce the most natural form of milk kefir as it was traditionally made.
