Joseph Hanna
Registered Oral Health Therapist · Founder, BumblCo
Melbourne-based registered Oral Health Therapist with eight years of clinical experience. For most of that time I've worked with sensory-sensitive and neurodivergent kids, and one problem came up over and over: every kids' toothpaste burned. BumblCo is what happened when I stopped recommending other people's products and started building one.
