Dr Oppenheim

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!


Dr Montero

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.

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.

Immediately after University, she completed her Doctor of Dental Medicine Degree at University of Illinois at Chicago and graduated with several scholarship awards.
