Dentistry has come naturally to Dr. Lynne Schopper. As the third child in a family of five, she took advantage of the unique opportunity to spend time with her father, Dr. George F. Schopper, by helping out in his dental office. At the age of 14, she began working in her father's practice as an assistant, receptionist and lab tech -- wherever she could be used.

The invaluable experience that she gained while working in the office through high school and community college furthered her interest in dentistry and led her to attend Creighton University where she attained an undergraduate degree in chemistry. She graduated from the University of Missouri School of Dentistry, at which point she returned to the family practice, where she furthered her learning by working directly with her respected father. "He taught me the value of the work we do and to treat each person who walked into the office as a whole person with kindness, respect and dignity" explains Dr. Schopper. This warm and compassionate style of care stuck with Dr. Schopper and has become the core of her practice to this day.

Being a woman in the field of dentistry has allowed Dr. Schopper the opportunity to inspire young ladies in the community to pursue their professional dreams. Her graduating class contained only 14 women and 146 men! Pursuing dentistry when woman in the field were considered a "novelty" set Dr. Schopper apart and allowed her and her father together to offer "the best of both worlds" to the community. She cherishes her part as a role model in the community and encourages all young women to follow their own distinctive path.

Dr. Schopper is a member of several respected organizations. Throughout the years she has volunteered to serve on committees for organized dentistry. In 1998 she became the first female president of the Fifth District Dental Society. She has served as a delegate to the Kansas Dental Association (KDA) and remains an active member. Dr. Schopper is also an active member of the Academy of General Dentistry (AGD) and Academy of Functional Orthodontists (AAFO). Dr. Schopper's work and talents in the field of dentistry have been noticed, and she's been inducted into both the prestigious International College of Dentists and the American College of Dentists.

She is married to Frank Theisen, an oral surgeon. Together, they have two wonderful children, Danny and Katie.

Dr. George F. Schopper's motto was "treat each person as if they are your family," and this has guided and directed Dr. Lynne Schopper's style of care since she's taken over the practice. She and Dr. Grosdidier invite you to experience the caring family and community atmosphere in their practice.

In 1995, Dr. Addy delivered her first appliance to help relieve a patient’s snoring. This proved so successful that Dr. Addy started to treat more and more patients and soon realized what a valuable option Oral Appliance Therapy (OAT) was to herself and her patients.

In 2000, Dr. Addy joined the American Academy of Dental Sleep Medicine, where she is now a credentialed Diplomate and Board Member. She continues to increase her knowledge and commitment in the treatment of apnea and snoring by following the recommended guidelines for treatment with intra-oral appliances in OSA and snoring management.

Other types do exist but can be limiting.  At present, she prefers to work with several types of adjustable appliances, choice of which is dependant on many patient factors.

Dr. Addy is devoted to the well being of her patients and communication with referring members of the medical and dental fields. Her commitment to offering patients an option to treat their OSA and snoring is saving lives and marriages every day.
