A Guide to Breast Augmentation

Dr. John Diaz believes every patient deserves the knowledge and confidence to make informed choices. That’s why he authored A Comprehensive Guide to Breast Augmentation—a trusted resource designed to simplify the process, answer common concerns, and help women achieve natural, beautiful results. Drawing from his experience as one of Beverly Hills’ most respected plastic surgeons, Dr. Diaz offers the same care and insight in this book that he provides to patients in his practice.

Educating Patients
Beyond the Office

Dr. John Diaz extends his commitment to patient education well beyond the consultation room. On social media, he offers clear, no-nonsense breakdowns of trending procedures and candid commentary on celebrity treatments—helping patients separate fact from hype.

Through The Plastic Principle podcast and his YouTube channel, Dr. Diaz shares in-depth conversations and videos that walk patients through what to expect before, during, and after treatment. His goal: to make trusted, expert knowledge accessible to anyone considering plastic surgery.

Areas of Expertise

Dr. Diaz’s credentials speak for themselves: recognized by Newsweek Magazine as one of America’s top surgeons, ranked in the top 5% nationwide by Allergan, author of The Comprehensive Guide to Breast Augmentation, and past President of the Los Angeles Society of Plastic Surgeons. Yet his reputation rests on something more valuable than accolades––results so harmonious that people notice you look refreshed and confident without knowing exactly why.

From facelifts and rhinoplasty to mommy makeovers and his innovative Infinity Breast Augmentation technique, Dr. Diaz offers comprehensive expertise across all areas of aesthetic surgery.

He performs procedures at his fully accredited private facility, supported by board-certified anesthesiologists and experienced nurses who maintain his exacting standards of safety and care.
