Dr Lise Woodward

GDC No. 100447

I am Lise Woodward and I am an associate dentist at The Smile Rooms. I qualified from the centre of excellence The University of Copenhagen, Denmark, in 2003 and have worked in private practice since I qualified 15 years ago. I have worked in the U.K. since 2006 when I moved to York with my husband and fellow clinician Duncan.

During the last 15 years I have completed numerous dental courses including a year’s post graduate restorative course via Leeds University in 2008. I very much enjoy the restorative pathway with a strong passion and interest in prosthodontics - the construction of fixed/removal dentures, crowns - and bridges.

In my spare time I am devoted to my family - especially my husband Duncan and our daughter Eva. We enjoy regular trips back to Denmark to see family and friends. I enjoy the outdoors and an uplifting run in the beautiful English countryside or a coffee-trip to Copenhagen or Paris! I love a well-made, beautifully presented, strong and tasty coffee (I am a Dane...!).

I'm looking forward to meeting all the patients at The Smile Rooms in Malton and to practice my very best on a daily basis in an environment where patients come first.

Kerry Slater

Dental Hygienist
GDC No. 5596

Hello I’m Kerry and I’m part of the hygienist team at The Smile Rooms.

I’ve worked in dentistry since 1989, firstly as a dental nurse then as a hygienist from 1999.

I have worked for The Smile Rooms since 2006, but Catherine and I first worked together from 2000 at a private practice in York. I thoroughly enjoy my job and have loved the work from day one, having a super support team here at the Smile Rooms is a great bonus.

I enjoy all aspects of the work, from helping phobic patients overcome their fears, to restoring a patient’s smile simply by removing unsightly stain. To relax I enjoy photography, cake decorating and of course spending time with my husband, David & Son Jack; together we like walking, cycling & running.

I live in York and enjoy spending time with my husband Jim and daughter Lucy. When I have the time, I enjoy going to music festivals and concerts and I also like to keep fit doing a bit of running. I have an allotment which I try to tend as often as possible although the weeds often grow better than the veg!

It is very satisfying to help change a person's feelings about the dental visit and here at the Smile Rooms we all want the very best for everyone.

My husband John and I enjoy our grandchildren, eating out and the odd holiday.
