Our Optometrists
At Onlookers Opticians, we provide the most thorough and complete eye examination using the latest technology. We understand that no two patients are the same and the eye examination is tailored to meet your precise needs. Our Opticians have undertaken additional qualifications and use the latest technology to give our patients the care they deserve. In addition all are MECS registered so are able to see you for NHS funded emergency Eyecare.

Outside of work I enjoy playing tennis, horse riding, running, the gym and walking my gorgeous dog Luna around the Wolds. I have been learning the piano for many years with limited success. I also love to travel and have been lucky enough to have visited many far-flung places over the years.
I love my job as I enjoy meeting and helping our wonderful patients, and at Onlookers I have access to the latest technology such as the OCT 3D scanner and Optomap wide field imaging system to provide the highest standard of care.
