Extremely customer hostile labwork checkin policy. Advertise 8am opening time. Lab person doesn’t turn up until 9am. Of course, there’s now a waiting list and it will be an hour or more before you can be seen. You can’t leave because you’ll lose your place.

As always, the practitioners at One Medical were spot on with diagnosis and treatment. My husband and I switched to One Medical nearly two years ago, and we talk about how lucky we are to have this highly skilled and engaged team caring for us.

I was charged $500+ for a routine preventative care appointment (pap smear) because the provider double-billed the appointment. Contesting the charge has been a considerable time sink. I would strongly recommend against receiving care here.

One medical used to be great, you paid an extra $200/year to get better service…lower wait times, better technology, etc. however, this has gone away and it’s essentially a regular doctor’s office with better decor / branding and snootier staff.
