SIMON POTTER
BSc (Hons) MCOPTOM

Simon has followed in the footsteps of his grandfather and father, as the third generation of Optometrists in his family.

 

He started his career in optics over 25 years ago when he started working in his family’s independent practice in Hull as a trainee Dispensing Optician. Simon qualified as a Dispensing Optician in 2002 after studying at Bradford college. He continued to work in the family practice after qualifying but after a few years he decided to build on his experience by moving to a busy high street practice in Beverley, where in just over a year he was promoted to practice manager.

 

He has continued in his professional development and learning journey through the years. In 2016 he qualified as a Contact Lens Optician which meant he moved into a more clinical based role. Simon then was given the opportunity to take a year out of practice in 2022 for intense full time study to qualify as an Optometrist via the career progression route at Bradford University. He qualified as an Optometrist with a first class honours degree in 2023 and recently joined us in 2026 as a resident Optometrist.

 

Simon enjoys building a rapport with patients, he strongly believes that it is important that each patient feels valued and cared for as an individual. He feels that the availability of the latest diagnostic technology at Onlookers is of great benefit to patients, helping detect ocular and general health conditions even at an early stage. Having worked in the profession for many years, he feels that the selection of spectacle frames, sunglasses and lens options offered at Onlookers means that patients can enjoy great vision and styling options that can be truly individual.

 

Outside of work, Simon enjoys travel and spending time with his family. He enjoys cycling and keeping active, as well as playing the drums over the years in various bands. He is a die hard Hull City fan and enjoys cheering them on at the MKM stadium on match days.

Ellen graduated from the University of Manchester Institute of Science and Technology and qualified as an Optometrist in 2003, and within 6 months was working back in the NHS Eye Department on the Hull Royal Infirmary site, where she has now worked for the last 22 years continuously. Over those years her qualifications and experience has grown significantly.

Ellen continues to work 4 days per week for the Eye Clinic,
but says she is fortunate to also be able to work at Onlookers and really enjoy meeting the patients and being able to utilise her hospital knowledge to support and advise patients in a community setting. Ellen also remains hugely impressed by the excellent technology available (in particular the OCT scanners, Optos wide field imaging and Humphrey Visual Field machine) that support the Optometry team in diagnosing eye conditions and managing the needs of patients optimally. Additionally, the fabulous staff and wonderful environment make Onlookers a very special place.

Outside of work, Ellen likes to be outdoors and keeping active. Loves running in the Wolds, gardening and growing her own fruit and vegetables. Ellen also has various voluntary roles in her local community and enjoys coaching at her sons competitive swimming club.

SARAH NEAL
BSc(Hons) MCOptom
Sarah started wearing glasses at just 5 years old. From that day onwards, she was inspired to become an Optometrist herself and help others in the same way. She followed this dream all the way through school and graduated from Cardiff University with a 2:1 Optometry degree with Honours in 2012. She then went on to complete her pre registration year the following July.

Since qualifying, Sarah has been extremely happy that she was so determined to achieve her childhood goal. She loves every element of community Optometry! Her favourite thing about the job is getting to know each patient. She is great at building a rapport such that we can resolve any issues with the eyes or refer on efficiently to the appropriate secondary care.

She finds that all the staff at Onlookers make a fantastic team, such that, together we can provide excellent eye care for each and every individual who attends the practice.
Outside of work, Sarah is always busy socialising with friends and family. She likes exploring new cities and discovering new places to see. Sarah loves going to gigs and music festivals (so much so that her kids have decided they want to join in too!)
