Guys I have really good expired listings around my area. What do you believe is a good way to approach them if they do not have a phone number?

Hello team my name is Javier Sardinas, I am 20 years old, My goal is to have 3-4 listings a month and I know with this academy it will take me further than what I want to reach. I've worked with Alexis in doing an open house for him recently and I can tell you this guy is the real deal. Can't wait to grow with this community. Lets GET TO WORK!!!
