Who is Hammond & Dummer?

With Claire Ranger at the helm, Hammond & Dummer is an independant, family run business with a focus on clinical excellence, cutting edge technology balanced with a family centric approach.

A lot of our patients have asked us whether there are other branches of Hammond & Dummer or alternatively is the practice a franchise. No, our practice is the only independent optician in Central Milton Keynes. Hammond and Dummer is a single family run practice, no franchises or large multinational companies in the background holding shares and directing the business; it is Clarie Ranger and her extended family delivering exceptional eye care.

Meet the Team

Claire Ranger BSc MCOptom DipTp(IP)

Owner and Prescribing Optometrist

Claire Ranger BSc MCOptom DipTp(IP), Hammond & Dummer

Claire studied at the University of Bradford and gained experience in Chesterfield during her pre-registration year. She then gave into her wanderlust and went travelling for three years before returning home to Dunstable.

She went on to postgraduate study in London before gaining hospital experience locally. For a time, Claire worked in independent practices within a radius of twenty miles from Milton Keynes as a locum before buying Hammond and Dummer in 2004 with her husband Bob.

Claire has a special interest in children’s eye care and the pathology of the eye. She continued to study and has gained a Diploma in Independent Prescribing that enables her to prescribe medication just like your GP.

Claire was wearing glasses at age 7 and then contact lenses when she was 14 years old. She has a prescription of -12.00 and so totally understands what it is like to wear glasses and contact lenses.

Dr Bob Ranger



Bob practiced clinical biochemistry in the UK and USA. Patient care has been a paramount aim of his whole working life and this is still the case with Hammond and Dummer.

Support of Claire’s work in optics keeps Bob busy whist offering facilities management to the practice.

You can see that Bob has a taste for the eclectic in eyewear.

Valeriya Monastyrskaya

Valeriya Monastyrskaya

Val has built her optical career at Hammond and Dummer and will hopefully qualify as a Dispensing Optician very soon. She is a full time contact lens wearer and has many pairs of glasses. This makes her very fussy about her eyewear, so unless the fit is correct and they feel very light and stylish she would not wear them. She does not expect anything less for her patients.

Emma Shoffren BSc MCOptom

Ophthalmic Optician

Emma Shoffren BSc MCOptom

Emma completed her qualification at City University, London and continued to be based in London for her pre-registration year. After many years of experience working in practices in the Hertfordshire area she joined the team here at Hammond and Dummer.

She has a special interest in both childrens’ vision and binocular vision. Shortly after becoming part of the team here she introduced the ReadEZ screening system to the practice to help those suffering with visual stress and plans to further her qualifications in this area in the future.

Emma mainly wears glasses, but has contact lenses which she wears socially.
