As her Dad would say, “Aim was a winner” and always excelled in life. She graduated in 1971 from Archbishop Bergan High school in Fremont, NE and was her high school’s homecoming queen. She then completed undergraduate and post graduate studies at the University of Nebraska and completed a career as a compassionate teacher and guidance counselor for the Scotia, Milford, Colorado and Lincoln Public Schools for over 30 years.
Aim was very proud of her Irish heritage and got the opportunity to visit Ireland with her two girls after she retired. She loved to travel with her sissies, kids and friends to craft shows, hiking in Colorado, Irish festivals, Husker football games, etc. She also loved her dog Murphy, attending the theatre and musicals, gardening and planting flowers, and watching the St Louis Cardinals and Husker volleyball.
Foremost though, she looked after and cared deeply about her family, friends and others. She raised three beautiful children and loved her seven grandchildren. She made holidays extra special for her family. It wasn’t Christmas without Aim’s laughter and her full platter of Christmas treats (including her famous rockie road clusters) she made with her girls each year. It was rare that Aim ever missed a family party.
She also made a lasting, positive impact on others through her job as a teacher, counselor and mentor at TeamMates.
Aim was loved and respected by all. She was our Aim.
She was a wonderful person that left us too soon. It’s hard to imagine a world without her in it. We will love and miss her forever.
