I am so impressed with the doctors and staff at this practice. This is my local clinic and I haven't had the need to visit for a number of years until the other day when I nearly chopped my finger of with an axe. Being in a lockdown during covid as you can imagine they are extremely busy. They dropped everything for me, (at the end of the working day mind you) to stitch my finger up. They could have easily told me to go to a hospital, but they didn't. So caring and compassionate. I recommend
