A note on your visit costs

We’re committed to being transparent about what you’ll owe before you arrive.
 
You may now receive an estimated cost ahead of your appointment, with the option to pay in advance.
 
This reflects a broader shift across healthcare toward upfront pricing
— so you always know what to expect, with no surprises after your visit.
