Looking for a Trusted Marketing Agency

I’ve been running a dental practice for a few years, and while word of mouth brings in a steady stream of patients, I believe there’s still untapped potential to reach more people in the community. I’ve heard that listing my practice in an online directory could help attract patients actively looking for dental services, but I’m not sure which directory would be most effective. With so many options out there, it’s hard to decide. Has anyone had success with a directory that significantly boosts visibility for local businesses?
