I haven't done this well, I'm just repeating what others have said, but are you trying to meet these surgeons in person in any way? Like you promote with your site, if you make just one connection with one bariatric surgeon that works with you, that's totally worth it.

Patrick McKenzie and Brennan Dunn advocate in person presentations at local chambers of commerces for example, so maybe there's some type of marketing or business summit for these surgeons that you can speak at or attend.

Another idea. You and I both know that people search Google for everything. So why not rank your own agency or consultancy for those you're going after. It's possible there are surgeons out there searching "how to get bariatric surgery patients" or something similar. Maybe only 5 searches a month, but you know the value of each of those searches.

Many in the agency/consulting world advocate high-touch sales and networking as the best way to get clients over ads or organic search, since it's a closer relationship required with lower volume.

Would love to hear what you try and what works!
