The Practice

Our philosophy


Our practice was founded over 40 years ago by Dr. Paul Dieter Vollmar. In 2002 Katja Jonuleit took the reins and was joined in 2003 by Sabine Proffen.

Ever since then, we have taken pride in continuously modernising our practice, in creating a welcoming, comfortable and functional space to make your dental visits pleasant and positive experiences. 

The surgery has 4 state-of-the-art treatment rooms overlooking an alley of wonderful old sycamore tree. Each room is equipped with big comfortable American dental chairs.

Our friendly, talented and competent team genuinely strive to make your visit as enjoyable as possible.

 you smile. we care., plays a pivotal role in the type quality of care we seek to give our patients of all ages.

By being dedicated to continuous learning, providing modern and gentle dentistry techniques, the latest in cutting-edge technology and the most advanced skills & services, we are convinced you will smile freely for a long time to come.

We demand nothing less of ourselves than a reputation our patients trust and our staff is proud off.


“Our physical well-being is directly linked to our dental health.”

Katja Jonuleit

payment plan

Financing should not be a barrier to the quality of care you receive.

Dental insurance generally does not cover the full amount of the fees. To help you budget for your dental care, we work closely together with a billing institute that can tailor a payment plan specifically to your needs.

Don't hesitate to talk to us before treatment.

Post-operative care

A comprehensive aftercare leaflet indicating the guidelines to follow is provided. We also ask that you come in the next day to check on the healing process.

After extensive surgery, a telephone number is provided with which we can be reached in case of emergency.

Should it be necessary, we will gladly provide an ice pack to help with the swelling and the pain. 


dental-phobic patients

Very few people enjoy going to the dentist. 

In the same way fear is learned it can also, through positive experiences, be forgotten.

With the outmost concern for you fear and anxiety, we take the time to sit down and explain the procedure step by step insuring the treatment is fully understood.



recall service

We will gladly remind you of your next appointment.
