Mike O'Brien (swimmer)

He won American National titles in the 1650, 1000, and 500 yard freestyles, and more impressively, in the 500 and 100 yard freestyle set two American Records.

His 1000 yard record remained active for 13 years.

Michael Jon O'Brien (born October 23, 1965) is an American former competition swimmer who won the gold medal in the men's 1,500-meter freestyle event at the 1984 Summer Olympics and a bronze and two golds in the Pan Am Games.

Learning to swim at the age of only four, Mike joined a competitive swim team at five.

He developed as a talented competitive swimmer in grade school, and by high school was recognized nationally as an outstanding backstroke swimmer and freestyle distance swimmer with his early team, the Irvine Novas.

Newport Christian, the private high school Mike attended, lacked a swimming program, so he swam for the exceptional Mission Viejo Nadadores from his first year in High School.

In his senior year in High School, he distinguished himself as a premier American distance swimmer winning his first US National Championship with a 4:16.88 in the 500-yard freestyle.

He would take four more National Championships in his career.

The distance had recently been swum in 14:54 by Russian Vladimir Salnakov at the Moscow Olympics in 1980.

Salnakov had become the first person to break the 15 minute barrier, and in his home country, adding considerable interest by the press with his performance.

At the 1983 Pan Am Games, in the 400 IM he took a bronze medal.

On August 3, 1984, O'Brien's 1500 swim time of 15:05.2 was sufficient to take Olympic gold at the University of Southern California, where he would soon attend and compete in swimming.

Lagging five seconds behind O'Brien, American George DiCarlo took the silver.

Salnakov, however, did not compete in 1984 with O'Brien.

O'Brien's subsequent win nine seconds slower than the previous Olympic winner in the event was anti-climatic, but referring to Salnakov's faster time and more historic finish, "I think, though, that if he’d have been in the same pool swimming right next to me, I could’ve given him a good race.”

O'Brien won the tight Olympic race in August despite being involved in a minor car accident, just two months earlier on June 30 on the day of the trials in Indianapolis, where he suffered bruises on both knees, a chipped tooth, and a bump to the head.

In his early swimming career, he swam for Southern California's Mission Viejo Nadadores, one of the nations most outstanding programs, under Mark Schubert.

In his first year at USC, where he was coached by Peter Daland, he placed first in the 500- and 1,650-yard freestyles taking two NCAA titles.

Returning to the Pan Ams in 1987, he won golds in the 200 backstroke and the 4x200 free relay.

After college graduation from USC in 1988, he began work in insurance and real estate.

He did some work providing commentary for televised swimming competitions.

In the Newport Beach area and at the University of California, Irvine, he coached swimming.

In 1993, O’Brien and his wife Kristin opened and have since operated Mike O’Brien Swim Instruction, at various venues, including home pools in Los Angeles and Orange Counties.
