Dr. Diaz and Dr. Marcks met as residents in the Graduate Endodontics program at Loma Linda University School of Dentistry. Upon finishing the program, they established Moreno Valley Endodontics. Since that time, they have provided high quality endodontic services for Moreno Valley, Riverside, and surrounding communities.

Welcome Dr. Chun
As many of you know, Dr. Bonnie Retamozo has relocated to Maine and is no longer practicing with us. We are sad to see her leave, but we know that she is embarking on a new and exciting adventure, and we wish her well. We are happy to announce our new associate endodontist, Dr Minna Chun.
Dr. Chun completed her undergraduate studies in Cell and Molecular Biology at Occidental College in Los Angeles. She earned her Doctor of Dental Surgery degree from Loma Linda University School of Dentistry in 2018 with induction into the Omicron Kappa Upsilon National Dental Honor Society, honors in Endodontics, achievement awards in Endodontics and Operative Dentistry, and a teaching assistantship in local anesthesia. She went on to complete a General Practice Residency at the VA Medical Center in Loma Linda, then returned to Loma Linda University School of Dentistry to follow her passion for endodontics. There she completed her endodontics certificate and was awarded a Master’s Degree of Science in endodontics. In her free time Dr. Chun enjoys hiking, traveling, and trying new foods with her family and friends.
Dr. Chun is enthused to join our team and looks forward to treating patients with compassion and integrity. We are pleased to have her with us and we are confident that you will enjoy working with her as well.

Patient Reviews
Was recommended here from my dentist for a root canal. The staff is very friendly. I came in on Monday for my consultation and got a next day appointment. Came in Tuesday at 12 and got my root canal done. In and out in an hour. Zero discomfort during my procedure. The dr was very good. Honestly the easiest procedure I’ve had done. If you’re in need of a root canal, I would highly recommend moreno valley endodontics. Very happy patient. Thank you guys.
Dr. Marcks is amazing! I needed a root canal and am very nervous when it comes to the dentist. He was so unbelievably patient with me. And his nurse Maria was just as nice. I will definitely go back if I ever need a root canal again. So nice!
Great friendly service!!! Doctors are kind and make you feel at home.
Dr. Marcks is a GREAT, Dentist. He has an amazing personality. He makes you feel very comfortable and relaxed before and during the procedure. The office staff is a group of wonderful, professional people. The office is clean, beautiful and comfortable. My after pain was very minimum and tolerable. Dr. Marcks work actually erase the horror tales of root canal. Thanks for a job well done.
