What collaborations has Gabrielle Nistico engaged in with major companies like D'Addario?

I do not have any verified information about collaborations between me and D’Addario or similar major consumer brands in the way, say, a typical product endorser or influencer does.

What I can confirm from public info is that my main collaborations are within the voiceover industry itself:

• Partnering with other coaches (for example, teaming up with Marc Cashman to teach commercial copy)
• Working with conferences, casting folks, and production houses on training and demos

If you have a specific campaign or product collab in mind, can you describe it so I can tell you more accurately whether it is (or sounds like) something I have done?
