Masking Policy

For surgical patients and visitors, we are continuing our current visitor protocols to ensure appropriate patient care. 

  • One (1) adult visitor for assistance with drop-off and pick-up.
  • This visitor may accompany the patient to the perioperative area.
  • Visitors are not permitted in PACU or recovery areas.
  • One (1) visitor for colonoscopy and endoscopy patients, and they must remain in the designated waiting areas during the procedure and recovery.

Our philosophy and mission is to provide exceptional health care in our community in a timely, caring, and personal manner.

Colon resection

Performed for indicated purposes such as diverticulitis or the removal of large benign and malignant polyps, typically done laparoscopically.

Hemorrhoid banding

We perform a quick, safe and effective in office procedure to remove hemorrhoids, reducing the need for inpatient surgery.
