Covid-19 Safeguards 


We are still following current recommendations from the CDC for medical facilities and have the following precautions in place  to help protect our patients, staff, and community.

Patient Information:

  • Our office will communicate with you before your appointment to ask some screening questions. We will review these same questions to note any changes when you arrive for your appointment.
  • Patients are required to wear a mask while in our office. If you do not have one, we will provide you with one.
  • We will provide you with hand sanitizer that you may use when you enter the office. You will also find some in the reception area and other places in the office for your use as needed.
  • We provide each patient with protective eye wear for their appointment. This eye wear is sterilized after each patient use, but if you feel more comfortable bringing your own, we encourage you to do so.
  • We prefer that you come alone to your appointment in order to reduce the number of people in the reception area. A care-giver or a parent may accompany the patient. 
  • Please arrive 10 or fewer minutes before your appointed time.
  • Please call when you have arrived and we will let you know when we are ready for you to come into the office.
  • Please minimize the personal items you bring with you.
  • Appointments will be managed to allow for social distancing between patients. That might mean that youre offered fewer options for scheduling your appointment.
  • We will do our best to allow greater time between patients to reduce waiting times for you, as well as to reduce the number of patients in the reception area at any one time.
  • We will be checking your temperature when you arrive for your appointment. We are also screening our team members every morning. Team members and patients who do not pass the recommended readings will be asked to reschedule.  

We are using industry leading practices to help protect our patients and team.

Disinfection and Air-Filtration:

  • We have purchased fourteen Medify Air medical grade HEPA air purifiers with multi-stage filtration of particles down to 0.1 microns, which is smaller in size than Covid-19 at approximately 0.125 microns. Every room in our facility will have an air purifier, including each of our patient treatment rooms, one in the waiting room and one at our front desk area.  All fourteen purifiers will be operating continuously throughout the day. You can learn more about these air purifiers at https://medifyair.com/
  • To ensure air traveling through our facility from our heating and cooling system is disinfected, we have invested in a medical grade UV-C light system for our HVAC. There are 2 lights, one positioned at the return and one positioned at the supply of our HVAC system. This will allow the maximum time and exposure of the air to the UV-C light. You can learn more about this system here: https://www.honeywellhome.com/us/en/products/air/uv-air-purifiers/uv-air-purifier-with-airbright-odor-absorption-uv2400u5000-u/
  • We will continue to use EPA approved surface disinfecting solutions and using disinfecting protocols recommended by the CDC and OSHA between each patient. We will be increasing the frequency of disinfection of all hard surfaces in the patient waiting room, front desk, patient bathroom, door handles & light switches.

Enhanced Personal Protective Equipment (PPE):

  • Our team is provided with the highest quality PPE available.
  • Due to the additional PPE that our team will be wearing, we will be keeping our office cooler. You may want to dress more warmly for your appointment.


We will continue to closely monitor updates from the ADA, CDC, OSHA and the Department of Health Services and will continue to seek guidance from these agencies. We will keep you informed of any changes.

We are so happy to be seeing you again and will answer any questions you may have about the steps we take to keep you, and every patient, safe in our practice. If you would like to make an appointment, please call our office at 608-257-0116.  

Thank you for your continual support. We value your trust and loyalty and look forward to welcoming our patients, neighbors and friends to our office.



Like many Madison-area dental offices, Isthmus Dental, Ltd., has worked hard to put environmentally friendly office practices into place: they recycle paper, cardboard and all their dental models; have programmable thermostats and energy-efficient lighting and try to optimize water use. But this year, the practice took working green to a new level by installing a solar photovoltaic (PV) system.
