Along with his wife Ronni, he moved to California in 1972 where he did his Pediatric Residency at the University of California Irvine. He became Board Certified in Pediatrics in 1976, and has remained board certified since then. He and Dr. Wideltiz started their practice in Cerritos in 1979, and they moved to their present location in Los Alamitos in 1997. He is now a Clinical Professor of Pediatrics at University of California at Irvine. He continues his commitment as a  pediatric teaching attending for medical students and Pediatric Residents both in his office as well as at Miller Children's Hospital Long Beach.
