Dr. Casey

Dr. Michael Casey absolutely loves orthodontics! In practice for over 28 years, Dr. Casey enjoys getting to know his patients and making them laugh, even if he has to dance an Irish jig! Dr. Casey obtained his Bachelor of Science degree at Loyola University before earning his Doctorate of Dental Surgery and certificate in orthodontics at the University of Illinois in 1986. He was honored with acceptance into Alpha Sigma Nu, the Jesuit Honor Society. Dr. Casey is an active member of the American Dental Association, Illinois State Dental Society, Will County Dental Society, American Association of Orthodontists, Illinois Society of Orthodontists, Midwestern Society of Orthodontists, American Equilibration Society and the Southwest Dawson Study Club. A current resident of Lemont, Dr. Casey and his wife, Paris, have a son, Neal, and twin daughters, Natalie and Lea. In his spare time, he enjoys snow skiing, water skiing, swimming, golfing and playing with Boots, their Jack Russell/Beagle mix. Dr. Casey also likes to rock out to Elton John and Bruce Springsteen.

Dr. Cortopassi

Dr. David Cortopassi has been an orthodontist for over 20 years and has been a part of Associated Orthodontists since 1989. He dreamt of becoming an orthodontist ever since having braces himself in junior high. He knew that he wanted to be the person who helped create new smiles, build confidence in people and see their delight once that final bracket was removed. Pursuing his dream, he graduated in 1983 from Loyola University Chicago and later obtained his dental degree from Loyola University School of Dentistry in 1987. He continued his education at the University of Illinois-Chicago where he completed his master’s degree and orthodontic residency in 1989. Dr. Cortopassi is very knowledgeable and constantly stays up to date with the latest technological advances in orthodontics by being an active member of the American Dental Association, Will County Dental Society, American Association of Orthodontists, Midwestern Society of Orthodontists and the Illinois Society of Orthodontists. Dr. Cortopassi is married to the “greatest woman in the world.” In fact, he and his wife, Mary, have been happily married for almost 25 years and have three children: Chris, Mia and Dena. A furry sixth member of the Cortopassi family is their loveable dog, Nella. Having three kids has certainly kept him busy with school activities. Weekends are often spent watching Chris play football as a University of Dayton Flyer, or to Indy to visit with his daughter, Mia, and catch a Butler basketball game. And to round it all off, he even participates in Dena’s competitive dance competitions. Now this is a man who can do it all. In addition to knowing how to straighten teeth, Dr. Dave is also conversant in both Italian and Spanish and is extremely proud of his Italian heritage. When he gets the chance, he loves to ride his bike, cook, read a good book or challenge someone in a fun game of Trivial Pursuit. But what Dr. Cortopassi enjoys the most is knowing that when he leaves his family every day to go to work, he is coming to his other family at AO.

Dr. Soderquist

Dr. Scott Soderquist, better known as “Dr. Scott,” was born and raised in Bolingbrook, IL. These days, he and his wife, Angela, live in Naperville with their three kids Nathan, Ella, and Olivia and their dog, Daisy. Dr. Scott graduated from Bolingbrook High School in 1993, lettering in football, baseball and wrestling, with Academic All-American honors in the first. He then continued school and graduated in 1997 from Illinois Wesleyan University with a Bachelor of Arts degree in Biology. In 2001, he obtained his Doctorate with honors from the University of Illinois and graduated third in his class. While at UIC, Dr. Scott received multiple academic achievements, including Top Third Year Dental Student by the Illinois State Dental Society. He continued to the University of Illinois and completed a three-year orthodontic residency to obtain a master’s in Oral Science. He then published his master’s thesis in the American Journal of Orthodontics after graduating from UIC and has co-authored other articles as well. Do not let his baby face fool you . . . he is full of knowledge. In 2004, Dr. Scott joined Associated Orthodontists and still maintains an active membership at the American Dental Association, Illinois State Dental Society, Will County Dental Society, American Association of Orthodontists, Chicago Dental Society and is a part of the American Cleft Palate Craniofacial Association. He is currently President-Elect of the Will County Dental Society, a delegate of the Illinois Dental Society and an editorial board member of the Orthodontic Practice US. Dr. Scott is a certified Damon® System educator. He knows this system so well that he is president of the Midwest Damon Study Club. Yet, even with all this responsibility, he still manages to make time for his community by volunteering at the Will-Grundy Medical Center, Plainfield Central High School Career Day and the Give Kids a Smile program. When his busy life loosens up, Dr. Scott loves riding his ATV’s and snowmobiling with his family. Watching “Da Bears” and Blackhawks is a must for him. You might even find him sneaking in a game of Rock Band or Guitar Hero here and there.

Dr. Jones

Dr. Patrick G. Jones, more commonly known as “Dr. Pat” to patients (and occasionally, “Dr. P-Diddy Jones” to fellow staff), is a Chicagoland native and a graduate of St. Rita High School. It was there that he discovered his ability to kick field goals for his football team, while still maintaining his GPA for National Honor Society in between plays. Dr. Pat went on to graduate from University of Illinois in Urbana, with a bachelor’s degree in Biology in 1991. Four years later, he graduated from the University of Tennessee College of Dentistry and received The United States Army’s Health Professions Scholarship. Associated Orthodontists is proud to say that Dr. Pat served in the U.S. Army from 1995 to 2003! During his service, he opened his own dental practice and provided comprehensive dental care and orthodontics for nine years. He returned to school for orthodontic specialty training from Jacksonville University and was the president of his class. He is a natural leader and, as such, has received many honors in both college and dental school! Associated Orthodontists was happy to welcome Dr. Pat in 2010 as a part of our team. But being an orthodontist is only a small part of his very busy life! To this day, he is an active member of the American Dental Association, the American Association of Orthodontists, the Midwest Society of Orthodontists, the Illinois Society of Orthodontists, the Illinois State Dental Society, the Will County Dental Society, and the Chicago Dental Society. You go, Dr. P-Diddy! Dr. Pat’s family life is just as active as his professional life. He and his wife Kathy settled in New Lenox in 1998 and have four sons: Nick, Tyler, Billy and Danny. There is never a dull moment in the Jones household. In his free time, he enjoys taking the family out for fishing trips. In fact, anything that has to do with water sports has them ready to dive in. Dr. Pat’s other passion is coaching little league baseball and basketball in the New Lenox community. But do not get him wrong . . .  even with four sons, Dr. Jones still has a soft side. He likes to think his secret talent is being a dog whisperer, so we can only guess how often he is caught talking to his dogs, Hollie and Ginger (baby voice included).
