Women smiling after receiving treatment at Karl Zeren DDS Here at Karl Zeren DDS, flexibility is important to us. That is why we strive to schedule appointments at your convenience and when time is available. Our Dental Receptionists and Office Manager will help you schedule appointments and complete necessary paperwork. They will also answer any billing questions that you may have.

Patient Appointments

Patients are seen by appointment only. We make every effort to be on time for our patients, and we ask the same courtesy from your family. Please arrive 15 minutes prior to your appointement, so our staff can greet you and make sure all of your personal and insurance information is complete.

If you cannot keep an appointment, please notify us immediately, giving a minimum of 48 hours notice to avoid any missed appointment fees. We realize that unexpected illnesses and emergencies may occur, but we ask for your assistance in this regard.

First Visit

Please allow 60–90 minutes for you initial visit, if you have an emergency every attempt will be made to see you that day. Dr. Karl Zeren will meet privately with you to review your medical and dental history, to better understand your needs, concerns and your treatment goals.


Karl Zeren DDS is a patient centered, private, fee for service practice. This means payment for service is expected at the time of your visit. If you have dental insurance we will file a claim(s) on your behalf with your dental insurance carrier. Please be sure to provide all necessary information regarding your insurance to assist us in processing your insurance efficiently. My staff is also prepared to assist you in meeting your dental expenses by working directly with financial institutions.

If you have questions about our scheduling, please call (410) 316-6141 or use our Appointment Request Form.
