Leo Timothy Considine, 81

Leo Timothy Considine passed away on August 23, 2017 in Billings, MT.  He was born October 17, 1936, in Cando, ND to William H. and Ethel (Michels) Considine.  While Leo was growing up, his dad was a Lt. Col. Of the 164th Infantry and was away from home a lot.  Leo learned at a young age to be responsible and respectful.  Most of his education was at St. Mary’s Catholic School in Bismarck, ND. He graduated from St. Mary’s, earning a football scholarship to University of North Dakota.

Leo married Kathryn Priske and three children were born.  Gary Lee, Douglas Jay and Kelli Jo.  They were later divorced.  Leo began his insurance career upon graduating from U.N.D. in 1958.  In 1972, Leo moved to Billings, MT and continued his insurance career.  He met and married Mardelle (McGee) Seymanski.  He obtained two little step-daughters, Brenda and Deena Seymanski.  Leo and Mardelle had one son, William.

Leo was a very successful insurance broker and through his awards, Leo and Mardelle were able to do a lot of traveling throughout the U.S., Europe, China, Caribbean, and Hawaii – with their favorite places being Hawaii and Ireland.  Leo’s life revolved around faith, family and friends.  He was a devout Catholic and served as an usher and Eucharistic Minister at St. Patrick Co-Cathedral.  Leo was a mentor to many and coached football for several years.  He was also a loyal Packers fan!  Many of Leo’s clients became dear friends and he loved to visit with them over a cup of coffee.

Leo was dedicated to his wife and family and treasured every moment spent with them!  Leo was dearly loved and will be missed by all who had the pleasure of knowing him.

Leo was preceded in death by his parents, grandparents, sister Virginia Volk and son Gary.  He is survived by his loving wife Mardelle, sons Billy (Sally) and Doug (Laurie), daughter Kelli (Shauna) and  step-daughters Brenda Johnson (Tim) and Deena Kalk (Brian Stolp).  Leo is also survived by grandchildren Tami, Natasha, Judi, Breanna, Niki, Whitney, Maci, Malori, Levin Garrett, Travis, Tyler and 7 great-grandchildren; sisters Caroline (Steve) Reis and Marcia Weaver and numerous nieces and nephews.

Visitation will be held at Smith Downtown Chapel from 4:00pm to 8:00pm Monday, August 28, with Rosary recited at 6:00pm.  Funeral Mass noon, Tuesday, August 29, at St. Patrick Co-Cathedral.  A second service will be held at St. Charles Catholic Church in Bowman, ND on Thursday with burial following at the Bowman Cemetery.
