Seo for healthcare practices from someone who had no idea what they were doing a year ago

We're a two-doctor optometry practice that's been growing steadily and I'm at the point where the manual follow-up stuff is eating into time that should be going somewhere more useful, we're still calling patients to confirm appointments, still sending reminder cards in the mail for annual exams, still manually requesting reviews which we do once in a while when someone remembers.
I know there are tools that automate all of this and I've gotten sales calls from a few, but I'm also aware that healthcare practice software is a space full of things that promise more than they deliver and contracts that make it annoying to leave if it doesn't work out. The math I keep doing in my head: if we reduce no-shows by even 3 or 4 per month and recapture a couple of lapsed patients who were due for an annual and slipped through, the tool pays for itself at almost any price point they're asking, but I need to believe the automation actually produces those results rather than just making the spreadsheet look nice.
What has the actual experience been?
Not the sales deck version, the real version.
