Dr. Randolph Cross
Dr. Cross is a published researcher, international lecturer, and serves as a Key Opinion Leader for EndoDirect and Vista Apex, and co-developed and patented the Endocator™ disinfection detection technology used in his own practice.
Before specializing in endodontics, Dr. Cross served as the Dental Director for Clinica de Salud del Valle de Salinas and Salud Para La Gente, providing care to underserved populations in Watsonville and Salinas. This experience deepened his understanding of the importance of accessible, high-quality dental care — a commitment he continues to uphold in his practice today.
Dr. Cross earned his dental degree from the University of California, San Francisco (UCSF) and completed his endodontic residency at the University of Southern California (USC). He is an advisor for several dental companies, including Vista Apex and EndoDirect, and holds multiple patents in the field of endodontics. He has also been engaged by Morita to provide product training for other clinicians. His dedication to innovation is reflected in his development of a rapid chairside disinfection test, which he has discussed on The Ruddle Show, the AAE's Endo Voices podcast, and Dentistry Uncensored with Howard Farran.
Outside of his practice, Dr. Cross enjoys spending time with his wife and two children, picking strawberries, practicing Spanish, surfing, sharing bad dad jokes, running at Nisene Marks, and encouraging his kids to join him on weekend outdoor adventures.

Designed to ease anxiety, not add to it.
Nitrous Oxide Sedation
Light, safe sedation available for anxious or nervous patients — relaxed but fully in control the entire time.
3D Video Glasses
Watch a movie in 3D during your procedure — a welcome distraction that makes time fly.
Anti-Anxiety Medication
Another option for anxious patients is an oral anti-anxiety medication, such as triazolam (Halcion), taken about an hour before your appointment. Because it can make you drowsy, you'll need a ride to and from our office, and all consent forms must be signed in advance.
As a Key Opinion Leader, lecturer, and inventor, Dr. Cross brings technology to Watsonville that most general dentists — and even many other endodontic offices — don't have, and personally trains other specialists on how to use it.
