Director of Scientific Education & Innovation, ProBiora Health

Dr. Rachelle Beattie McAlliey holds a PhD from Marquette University and has dedicated her career to the science of the oral microbiome — the complex ecosystem of bacteria that shapes not just your mouth, but your overall health. As ProBiora's Director of Scientific Education & Innovation, she oversees the research behind ProBiora3® and ensures that science actually reaches the people it was meant to help.

Rachelle is a recognized voice in oral health science, presenting to dental professionals through organizations like AAOSH on topics ranging from the role of the oral biofilm to the evidence behind probiotic therapy in dentistry. Her work bridges the lab and the real world — helping patients, providers, and anyone curious about their health understand why the mouth matters more than most people realize.

Great science shouldn't stay in the lab. Dr. Beattie McAlliey brings it here — clearly, honestly, and with the conviction that a healthier mouth genuinely changes lives.
