I think if you have time for this sort of thing, it is good. Once you have too many patients, you may not have time, but then again, maybe not be in a position to be able to take in new patients anyway.
For my child's pediatrician, we met with her first before the baby was born. The initial meeting gave us a good overview for baby care, how frequently to schedule visits, how administering the necessary shots plays out, all that good stuff that if you were a new parent like me, it was much needed.
What I like about you doing these initial meets is that anyone who may be concerned about how thorough you typically are, or are not, can find out befopre setting up that first exam. For example, if you typically do not perform thorough genital exams unless there's a pre-existing condition or a specified issue and the patient expects to have thorough genital exams annually, they can determine if you're right for them. i recently read about one younger than 50 patient with a family history of colorectal cancer who was upset that his doc did not perform a DRE, & was considering finding a new doc who would. So this way, by having these up front discussions with prospective new patients, patients can know what to expect, and you as a doctor know what your patient needs/expects from you.
And what happens with new patients? You start files, gather all that family history, forms, documentation, all that good stuff. And then after one exam, the patient decides you're not right for him/her. All that time & resourcing to put together paperwork that will now go to the trash can.
