Product-Agnostic Training

Master painters don’t create masterpieces with just one color
— why should you?

Our trainings blend techniques and products for the best patient outcome – because when that’s the focus, everyone wins.

No hidden agendas. No ulterior motives. Just real, high-quality, actionable training that helps you build your empire.

Community that Elevates

A true community isn’t built on competition—it’s built on shared knowledge, mentorship, and a commitment to growth.

That’s the community we wanted. It didn’t exist – so we’re building it.

If this aligns with you,
let's work together.

If you're looking for a membership disguised as training,
we're probably not for you.

But if you want to master your craft, grow your business, and be part of something bigger-

Welcome.

Not my first training with Wendi and Dierdre. Not my second, and definitely not my last. They are amazing. Dierdre is a business wiz and Wendi a clinical superstar. The training more than paid for itself after just one patient using the protocol they taught.

Heddy training with Dierdre and Wendi was an incredible weekend. Their injector-friendly approach-practical and versatile-delivered top-notch education and stunning results with any filler or biostimulator. Wendi’s engaging didactics and hands-on techniques were invaluable, boosting my skills and confidence. Plus, connecting with my peers made it fun and inspiring. I’m already eager for more—thank you Dierdre and Wendi.

Thank you. The training was fantastic and the pearls mixed with fellowship was special. We are excited to start doing all of this. I would love to get into depth with you regarding your marketing model, your actual technique on penile enhancement and cellulite treatment. Thank you again for your friendship and willingness to teach.

Best training I've ever attended. The protocols and clinical pearls were invaluable. Dr. Wendi & Dierdre's unpretentious, real-talk style made everything click. I treated one patient using Heddy's facial balancing approach and the training already paid for itself! Total game changer for me and my patients.
