Dr. Clayton Simon - Veterinarian


Clayton Simon grew up with a pack of dogs in Southern California.

He attended Acton Elementary, Palmdale High School, then graduated from UC Irvine with a degree in Biology. After 4 short years, lots of study, and many miles bicycle riding, Dr. Clayton Simon graduated from UC Davis in June 1992.

Dr. Simon's first employment out of veterinary school was at Crown Valley Animal Hospital in Laguna Niguel from 1992-1997. He learned lots of great medicine from the team of doctors that worked there during those days. He was then employed at Moulton Animal Hospital in Laguna Niguel from 1997-2002 when he learned much about the business aspect of the profession from his mentor and friend Dr. Peter Weinstein.

In 2002 the Simons ventured out on their own, converting an abandoned Chinese restaurant into into Marina Hills Animal Hospital. Dr. Simon enjoys the relationships he has formed with pet lovers in Laguna Niguel, and throughout the Saddleback Valley (some have moved great distances and still return to Dr. Simon for pet care), some dating back to 1992! He knows that his fortunate circumstances grow from the care and instruction he has received from other people throughout his career, for this he is grateful.

Dr. Simon's interests beyond veterinary medicine include a wide range of DIY home improvement projects (the best projects include the purchase of new tools), and the collection of cichlid fish from Malawi, Africa. He is a Christian, a student of the Bible and strives to follow Jesus as Lord in every aspect of his life.
