Temporary Practice Closure March 23, 2020

Dear Valued Patients,

Please be aware that our administration has been working diligently to triage and re-schedule all appointments during this difficult time. Our office remains open for telephone inquiries and support. If you have an appointment in the next 3 weeks please feel free to contact us to reschedule. If necessary, Dr Wismer and Dr O’Malley will be available through phone or virtual consultation.

We will be monitoring this situation carefully to ensure the safety of our patients and to do our part in helping to “level the curve”. We appreciate your patience and understanding in working with our office to keep everyone safe and healthy.

Please check back in this space for further details on when the practice will reopen.
