Meet the Doctor
Dr. Yolanda Mangrum
DDS, MAGDOwner, Petaluma Dental Group | Founder & CEO, Smile More Longevity Campus™
“Live wisely, love well, and serve greatly.”
This personal vision guides Dr. Yolanda Mangrum’s approach to dentistry, leadership, and community service. She believes exceptional care begins with understanding the whole person—their health, concerns, goals, and what matters most to them.
A graduate of the UCSF School of Dentistry in 1997 and a practice owner since 1999, Dr. Mangrum purchased Petaluma Dental Group in 2009 after establishing her first practice in Sonoma. She has continued to shape PDG into an innovative, eco-friendly, multispecialty practice where clinical excellence and compassion work together. Her approach connects oral health with whole-body wellness, helping patients make informed decisions that support their health throughout life.
That vision has grown into Smile More Longevity Campus™, bringing together Petaluma Dental Group, Smile More Orthodontics, Allume MedSpa, and Luminary Education Center. Guided by “Smile More. Live Longer.™”, the campus connects dentistry, wellness, esthetics, and education to help people take a more proactive role in their health.
Within Petaluma Dental Group, Dr. Mangrum champions personalized care that considers the relationships among oral health, airway and sleep, jaw function, and overall well-being. Across the campus, her goal is to help people understand their options, identify meaningful next steps, and build habits that support healthier, more fulfilling lives.
Service has been a defining thread throughout her career. Recognized as a Fleming Humanitarian Scholar in 1994, 1995, 1996, and 1997, Dr. Mangrum carried that commitment beyond dental school into community outreach and international service. In 2020, she received the Academy of General Dentistry Humanitarian Award for her service to local, regional, and global communities. Her efforts have included organizing relief for Northern California wildfire survivors, participating in dental missions in Haiti and Vietnam, and supporting dental outreach in Ecuador.
A lifelong learner and educator, Dr. Mangrum has served on the faculty of UCSF and the University of the Pacific dental schools and as president of both the Northern California and California academies of general dentistry. She founded Luminary Education Center to create a place where healthcare professionals and community members can learn, connect, and grow.
Whether caring for a patient, mentoring a colleague, or serving her community, Dr. Mangrum’s purpose remains the same: to help people live wisely, love well, and serve greatly.
