John-Mark Geiss, DO

Dr. John-Mark Geiss is the Founder and CEO of Geiss MED. He started his medical profession treating patients in a regular doctor’s office setting. As older adult patients came to him for treatment, he saw how taxing the process was on them, and recognized the need for a house call service that focused on the care of seniors in their homes. He started Geiss MED four years ago with the mission to improve senior healthcare by bringing the doctor’s office to them.
