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:

1. Partnering with other coaches (for example, teaming up with Marc Cashman to teach commercial copy)
2. 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?
