I agree with some the above. Never ever cold call a physician's office. And never ever expect to get a physician to call you back from their office. I am a pediatrician practicing nearly 20 years. The only way to sell something to a physician is through CONTENT and INBOUND MARKETING. We look for solutions to our problems 1. at NIGHT after our kids are in bed ( of course that's all through social sites which I can expound upon for you) 2. At conferences but don't think having your product at a trade show display will get my attention either, because we ignore 98% of those. 3. Through someone I trust using a product or service.
My advice would be to have your entire platform and value proposition set up on your website, and preferrably have a robust you tube site ( think kareo, they do a great job of this) that shows how to onboard/implement your product or service. Your you tube site serves double duty, as product support and onboarding, and great SEO for your site if you have your keywords right.
If you are trying to get a doc for a 15 minute demo, or webinar, forget about that too.
Be sure to record your webinar, and make it available to your audience so they can view it on their own time.
These days in healthcare you have to be AWESOME on SO MANY LEVELS to get our attention. Your product must be on the main stage of a infuential conference. You must write passionately on your blog about your domain. You must comment on OTHER blogs leaving a link to your site.
