More about Sarah

About My work

My accounting career began in my family’s engineering business, which I co-managed from 2000 to 2009. I later established my own accounting practice, which became Codex Absolute in 2013. Over the years, I have also gained valuable experience in the hospitality industry, further strengthening my customer-focused approach.

The most rewarding part of my role is helping clients and colleagues achieve their goals and celebrating their successes along the way.

Who Am I?

I enjoy spending time with my family and making time for a few favourite hobbies. I love getting lost in a good book, relaxing with paint-by-numbers projects, and challenging myself by learning Spanish.

Whenever I can, I enjoy travelling to Spain, where I love experiencing the culture, food, and sunshine.

At home, I'm kept entertained by my two lovely cats, Rick and Morty, who love to come out walking around the farm with us.
