Doug Cornish Head Coach/CEO, Interim AG Head Coach

Coach Doug is in his fifth year as the CEO/Head Coach of EMAC.

Doug began coaching in 2002 at STAR Aquatics in NC.  From 2002-2010, as Head Coach and Partner, Coach Doug helped build STAR Aquatics into one of the best teams in the Southeast.  STAR Aquatics went from unranked to 2nd at NC Age Group Champs, while the girls won NC Senior Champs in 2010.  From 2008 to 2010, STAR Aquatics amassed over 15 NC State Records.  In his final year, the team qualified 10 swimmers for Junior Nationals, while the team earned its first USA Swimming Bronze Medal Status.  STAR Aquatics earned Silver Medal status the following year.  

A Pennsylvania native, Coach Doug, his wife Chrissy, and their son, Dougie, relocated to Lower Macungie in 2010 to raise their family closer to home.  They've since added two children, Addie and Owen.    

From 2010-2012, as the Head Coach of LVA, Coach Doug improved the team performance significantly.  The team improved from 26th to 6th at MA Senior Champs.  Two swimmers earned their Junior National cuts, while two other age-group swimmers earned USA top-5 rankings in individual events.  

From 2012-2014, Doug served as the Director of Compettive Aquatics for the Hunterdon County YMCA.  The HCY Stingrays improved from 5 YMCA national qualifiers to 21 while doubling the revenue of Competitive Aquatics. 

From 2015-2017, Coach Doug helped BLUE Eagle improve from a relatively obscure team to one of the leaders in Middle Atlantic.  During that time, BLUE improved their VCC score from 81,742 to 137,743, jumping from 35th in MA to 16th.  Fifty-four percent of BLUE athletes earned an IMX score, compared to the national average of 13%.  During his tenure, with the assistance of an outstanding volunteer base, BLUE established themselves as one of Middle Atlantic's most trusted meet hosts, hosting 2016 and 2017 LC Silver Champs, 2016 Bronze Champs, and 2016 MA Mid-Winter Classic.  

Over the last four years, Coach Doug has spent much of his time promoting growth and change at EMAC.  He has worked to assemble one of the strongest coaching staffs anywhere.  In the process, EMAC has made dramatic improvements, having just come off the best year by far in both SCY and LCM VCC Scores. 

Coach Doug also serves as the Chair of the Technical Planning Committee for Middle Atlantic Swimming.   As an East Penn resident, he is honored to serve as a steward for the sport of swimming in the East Penn School District and surrounding areas.

Tim O'Connor Killer Bee Assistant Coach

Tim has been a teacher in the East Penn School District for over 20 years.  He recently moved from Eyer Middle School to the Emmaus High School, where he enjoys being more involved with the swimmers on a daily basis.

He began at EMAC in September of 1996 and was named Head Age Group Coach in October of that year. 

During his tenure at EMAC Tim was part of the expansion in purchasing the Emmaus High School Team's second home in Millbrook Farms, which was a year-round training facility. At this time, EMAC went through not just the physical growth of a training facility, but a team growth as well.  Progressively, EMAC's Age Group Program grew, as did their lessons and Senior Group through the idea of providing a foundation for all athletes to be prepared to swim all events, but also to compete against other teams and even against their own teammates.

Coach O was appointed to the USA Swimming Age Group Coaches Association Coaches Clinic at the USA Training Center in Colorado Springs, Colorado in 1998 and then he was named an Assistant Coach for the Middle Atlantic Zone Swim Team Championships for both the winter and summer teams of 1999. He was then named Head Coach for both Zone Team events in 2000. The Middle Atlantic Team won the winter championship. During his tenure at EMAC our swimmers qualified and competed annually for this team.

He stepped down from head coaching duties after the 2007 season but since 2010 he has progressively been showing up more and more at EMAC to assist in a variety of ways, including now serving as the Head Senior Coach for EMAC.

Tim's high school teams have won a combined 7 State Championships. He was elected into the Pennsylvania Aquatics Hall of Fame in 2015 and he is active with the PA High School Swim Coaches Association.

Tim is married to his wife, Tracie, who is a teacher at Eyer Middle School.  They have two children - Molly and Bailey.
