A DR GPT™ Labs venture
Expertise deserves a clear voice.
Harvey Castro, MD created Signal & Stage because expertise alone does not make a presentation useful. Audiences need clear ideas, relevant stories and practical takeaways.
That belief guides this curated speaker collective: people with firsthand experience and distinct perspectives, matched thoughtfully to each event’s audience.

For event planners
Plan with confidence.
How do I choose a speaker?
Start with your audience and the question your event needs to address. Compare topic areas, watch a speaking sample and tell us what you want participants to take away.
Can I ask for help choosing?
Yes. Share your event date, audience and topic in the inquiry form. You can leave the speaker field open if you are still exploring.
Can I discuss a virtual event or a different format?
Select your preferred format when you inquire. We will discuss the speaker’s availability and confirm the scope for your event.
Are the topics final session titles?
Topic areas help start the conversation. The final title, content and audience takeaways are confirmed with the speaker before the event.
What happens after I inquire?
We review the event details and discuss fit and availability. Sending an inquiry does not reserve a date. Scope and terms are confirmed before a booking is finalized.
Still choosing?
