Meet Joanne Oppenheim, DDS

My original major in college was elementary education. I always loved working with children (becasue children are so much fun!) but also loved science. I changed my major to biology and applied to dental school, knowing that I’d specialize in pediatric dentistry. I started practicing in 1994 and have loved every aspect of my career. My greatest satisfaction is when a child tells me how much they love coming to their appointments!

Personal Life

Dr. Oppenheim and her husband, Dr. Ken Kromash have been married since 1991. They love living in Chicago where they raised their two children. Their son, who volunteered with the Peace Corps in Paraguay for 2.5 years, then received his master's degree, now works for the environment in Colorado. Their daughter is graduating from the University of Chicago, Medical School in 2025 and is busy applying into a OB/GYN residency.

Being an empty nester, Dr. Oppenheim loves to travel. Usually they are active vacations, hiking, scuba diving, skydiving (OK once!) skiing and biking. But her favorite pastime is sitting at a pool, reading a book!

You might see her out in the neighborhoods walking her crazy rescue dog, Rustin!

Meet Marilia Montero, DDS

Dr. Montero has been practicing pediatric dentistry in Chicago for over 20 years and has seen her loyal patients grow from babies to adults, graduate from her office, and return with their own children. These long-term relationships with her patients are what motivates Dr. Montero to develop and learn about every advance in pediatric dentistry. Dr. Montero’s wide variety of experiences in academia, community, and organized dentistry have a common goal to improve children’s oral health and strive to provide the highest level of dental care in a gentle, compassionate manner while making the visit an enjoyable one for your child. She primarily focuses on educating both the parents and child on the importance of good oral health to prevent cavities.

At the beginning of 2011, Dr. Montero proudly stepped into the role of partner of Pediatric Dental Health Associates. Having already been with the practice for more than ten years, she was thrilled to expand upon the foundation set by Dr. Mary Hayes, 40 years prior. Additionally, she also has been leading a new generation of parents and patients with the latest procedures and technical advances in pediatric dentistry.

In 1992, Dr. Montero received her DDS from the Federal University of Ceara, Brazil. She then completed her two-year Advanced Education in General Dentistry (AEGD) at Eastman Dental Center in 1995 and General Practice Residency (GPR) at the University of Rochester, New York in 1996. In 2000, she received her Pediatric Dentistry certificate from the University of Connecticut. Additionally, she completed a Pediatric Dentistry fellowship at the College of Dentistry at the University of Illinois at Chicago in 2001.

Following this, Dr. Montero joined the faculty of the Department of Pediatric Dentistry serving several positions such as the Director of Boys and Girls club, the Director of the Infant Clinic and Postdoctoral Clinical Director of the Pediatric Dentistry Department. During that time period, Dr. Montero was promoted to the rank of Clinical Associate professor and awarded the UIC Underrepresented Faculty Recruitment Program Award and received the Chicago Dental Society Professorship Clinical Fellowship Award.

In 2015, Dr. Montero also received the Distinguished Teaching Award by Feinberg School of Medicine, Northwestern University, and Ann and Robert Lurie Children’s Hospital of Chicago, Department of Pediatrics.

Dr. Montero served as the President of the Greater Chicago Hispanic Dental Association Chapter and the President of the Illinois Society of Pediatric Dentists. Currently, she is the Executive Director of the Illinois Society of Pediatric Dentists. Recently, Dr. Montero was elected by the North Central District of Pediatric Dentists to be the North Central Trustee of the American Academy of Pediatric Dentistry.

Dr. Montero has a strong commitment to community outreach, she is an active volunteer in the community and often participates in the Special Olympics and Health Fairs in the city of Chicago every year. She has done clinical and educational outreach locally, as well as abroad in Costa Rica and Egypt.

Dr. Montero is a Diplomate of the American Board of Pediatric Dentistry and a Fellow of the American Academy of Pediatric Dentistry. Furthermore, Dr. Montero gives numerous presentations nationally and internationally.

When she is not working, Dr. Montero embraces life in Chicago, where she enjoys spending time with her family and friends, watching movies, going to restaurants, plays, musicals, and exploring Chicago.

Dr. Dominique knew she wanted to combine her love of children, teaching, art, science, public health and communication into one profession - pediatric dentistry was the perfect match! Immediately after University, she completed her Doctor of Dental Medicine Degree at University of Illinois at Chicago and graduated with several scholarship awards. After dental school, she matched to her top choice, Children’s Hospital Colorado, to complete her residency training. She proceeded to graduate with the excellence in research award.

Dr. Dominique has an extensive background in treating children with Special Health Care Needs and dental trauma due to Children’s Colorado being the number one hospital in the western region.
