All patients will be called and if the appointment is not essential, they may be rescheduled after May 15th, if they wish to do so. If they want to be seen sooner, they will be put on a call list, accordingly.

To comply with the CDC recommendation for social distancing, CSOF is developing a plan to implement ASAP a "TELEHEALTH" option for some routine check-up appointments in the presence of this pandemic to protect our patients from unnecessary exposure, to attempt to comply with <10 people gathering in our waiting areas and to protect caregivers.

All patients arriving to CSOF office locations will be screened prior to entrance to the office.

If you have any questions, feel free to contact our office.
