Dear valued patients,

let me first express my deeply felt gratitude: Many of you have been coming to my office for more than a decade. Thus, you did more than simply witnessing the flourishing of MeinZahn into a larger dental practice that houses several competent specialists under one roof – you are what made this development possible in the first place. Since I opened my practice in 2001, I have been continuously working on providing my patients with dental care that measures up to the highest scientific and technical standards of dentistry.

My vision has always been to gather a team of motivated and skilled specialists able to offer uncompromising treatment quality in all the important fields of dental medicine. It is with great joy and satisfaction that I can tell you now I have accomplished my mission. Please meet my highly qualified colleagues and partners: dentist Ingrida Mischitz, specialized in aesthetic dentistry, Dr. med. dent. Sandra Haas, general dental practitioner, endodontics specialist MDDr. Jana Chmeliková, and oral surgeon Dr.Dr. Ulrich Arhold. Thanks to this team of top notch dentists and specialists I am now able to devote increasing amounts of my time to general organization, conceptional planning and technical advancement of the MeinZahn practice. I will continue participating in practical dental work performing root canal procedures with the surgical microscope. Of course, I will stay involved in your treatment as an advisor, and I will take on the planning and oversight of more complex treatments.

Please be ensured that these new arrangements are not going to affect the quality of dental care at MeinZahn in any way – as guaranteed by the expertise and experience of the committed MeinZahn team of four under my guidance.

Yours sincerely,
Zsolt Fischer

Dear patients,

thank you for taking an interest in my work!

There’s much more to healthy teeth than being pleasant to look at. Dental health is closely connected with overall health. Your oral cavity, jaws, gums, teeth and all, is not only a component of your digestive system, but is anatomically and functionally coupled with your entire organism via the sceletal system, muscle, nervous system and bloodstream. Teeth and gum trouble can affect your general health – and systemic illnesses can weaken things in your oral cavity. Thus, there is ample reason not to forego your regular dental check-ups and professional oral hygiene appointments. Got questions about caries and parodontitis prevention?

I’m always happy to advise my patients on all things dental. My patient’s individual needs and wishes are very meaningful to me in my daily work. I strife to create a relaxed atmosphere of trust for everyone, including patients with anxiety. My ability to listen empathically helps me with this goal. I particularly enjoy working with the littlest MeinZahn patients. As a mother of two I have a natural, easygoing rapport with children, and I know just how important the right words and little gestures are to make a child’s dental appointment a positive experience. I follow the continuous, ever fascinating developments in the field of dentistry with an active interest, regularly brushing up on my knowledge by reading scientific publications, attending courses, seminars and education events.

As a MeinZahn team member, I am proud to be able to always offer my patients state of the art dentistry based on up to date scientific knowledge and using cutting edge tools and technology. I will be most happy to welcome you as my patients.

Yours, Sandra Haas
