All right. Really cool story for you guys about really never giving up on these patients. Pretty much all of you know, there was a time when I was selling almost full-time at a dental implant center so I could experience for myself and really build the arches for days course and understand everything that goes on inside the office. That was a long time ago. I was working, I mean, really, I was only selling for three days a week and still running the dental implant machine, obviously. So, insanely busy, spending about $7,000 in ads. Some of that was radio, which we didn't really get anything from, but I wanted to try it out. And sold over a million dollars in four months directly collecting it. But there've been a lot of people who have still trickled in.
And one guy, I just barely got word today that I presented to him a long time ago. He was really, really interested and pretty much said, "Yeah, I'm going to do this. I'm in the middle of selling my home." I followed up with him for several weeks in a row. Finally, he said, "Dewey, I promise when I sell my home, I'm going to come and get this done." And so, I said, "Okay, that's fantastic to hear. I can hear it in your voice. This is something I really, really want for you and I know you want it to, so I just didn't want this to be something that you give up on." I don't even know how many months ago it actually is, but it is so rewarding to see some of the footage they got of him and how amazing his smile looks now. And seeing his before and after picture really, really is rewarding.
And I just wanted , never ever give up on these people because you're changing their life. If you connect with them well enough in your consultation and you commit them, they will come back to you. And the return on investment, I mean, we're still getting a return on investment from the time I was in there. I don't even know what it is right now, but the return on investment of you giving your all in these consultations is priceless. Quick reminder for you there, guys. Never give up, they will come back.
