Robert Kaplan

Robert Kaplan, MD

is on staff at
CHOC Hospital Orange

Office Phone:
562-598-4848

Specialty:
Pediatrics

Board Certified:
Pediatrics

Dr. Robert A. Kaplan, MD, was in the private practice of pediatrics from 1975 until his retirement in May 2026. He grew up in New York, attended Penn State University for his undergraduate degree, and graduated from NY Medical College in 1971. He completed his Pediatric Internship in New York before relocating to California.

In 1972, he and his wife Ronni moved to California, where he completed his Pediatric Residency at the University of California, Irvine. He became Board Certified in Pediatrics in 1976 and remained board certified throughout his career. He and Dr. Widelitz founded their practice in Cerritos in 1979 and later moved to Los Alamitos in 1997. He served as a Clinical Professor of Pediatrics at the University of California, Irvine, and was dedicated to teaching medical students and Pediatric Residents both in his office and at Miller Children’s Hospital in Long Beach.

Dr. Kaplan and his wife Ronni have been married since 1971. She worked as an elementary school teacher in the Long Beach School District for many years. Their two children both attended the Los Alamitos School District and are now grown and married, and he and Ronni are fortunate to have five grandchildren. As empty nesters, they have enjoyed traveling throughout the country and around the world. Dr. Kaplan’s interests have included a wide range of sports — tennis, golf, bike riding, and skiing — and he has been active as a volunteer and consultant with many community organizations. He also served a four-year term as Chief of Staff at Miller Children’s Hospital and was a board member of the Southern California Children’s Health Network.

Throughout his career, Dr. Kaplan loved coming to work each day. The greatest joy of his practice was watching children and families grow over time. Caring for multiple second-generation patients was especially rewarding, and he took great pride in bringing warmth and experience to every family he served.

“I’ve been very lucky,” Dr. Kaplan says. “People have been very generous placing their trust in me. As I tell my patients and their families, I’ve learned as much from them as they have from me. They’ve made me a much better doctor.”
