Take me into the flow. You are on a page where you fill in a form. On submit, you are redirected based on input? or does selecting a nose job immediately show a list of doctors to select from and have that doctor to be selected before submit? Why not have an overview page with all practise offerings?
Don’t tell them it’s easier, tell them it makes way more sense for users to have the information available to them up front. Otherwise you are hiding information behind a choice users are not aware they are making.
