Our sad news
Our sad news

To our customers and friends,

We have some very sad news to share. Douglas Hanford, the co-founder of Koi Logic, passed away peacefully on Monday 7th August 2017 following a stroke. This was unexpected and we are deeply shocked and saddened.

He will be greatly missed by all his family, friends and also customers that have shopped with us over the years.

In lieu of flowers, we have set up a charity donation page raising money for the Stroke Association and RNLI. Doug was a keen sailor, owning a few different sailing boats over the years and always supported the RNLI.

Please find the link here:
