Meet Our Team


Office Manager

I love the conversations with our patients, catching up on the latest news, and meeting new people. Our patients are my friends and they feel like family to me. I’m glad to help people I care about develop healthy and happy smiles. I welcome patients to our office and make sure their visit is a good one. I work with patients to review their proposed treatment plans. I help them with their insurance, too. I also handle patient correspondence and scheduling.

I love spending time with my family, most of whom live only 10 minutes from me. I have a delightful Cockapoo named Bailey. I’m active with my church and their elementary school. I love volunteering to help with costumes and set designs for plays.


Patient Coordinator & Front Desk

Our patients are the best! My coworkers and our patients feel like family. I enjoy catching up with them at each visit. I handle our recare system, accounts payable and insurance, as well as a variety of front-desk duties. I do whatever is needed to keep everything running well.

I have two grown daughters who are in the nursing and dental fields, as well as two grandchildren who have captured my heart. I live in Sandwich and love taking short trips to anywhere to see the beautiful scenery that surrounds us. I also love to fish and garden in my spare time.


Dental Hygienist

I enjoy helping patients reach their goals of better oral and overall health. Each person has unique needs and desires. I encourage patients to talk about what they want to achieve, and then we work together to make it happen. I take patient histories, examine their mouth, and clean and polish teeth. All the while, I talk with the patient about the correlation between tooth and gum health and the health of their body. I want people to be able to make good decisions and create healthy habits.

I’m a proud mother of three grown children: Lauren, Colin, and Craig. When I’m not working, I love to read, garden, and work around my home on various projects.


Dental Hygienist

The best part of every day is knowing that each of my patients is healthier after coming to see me. I enjoy getting to know my patients as people, learning about their lives and interests, and becoming friends. My goal is to help each patient take control of their oral health, and I am happy to share simple, effective techniques. During visits, I provide preventive care and non-surgical periodontal therapy, and collect diagnostic images and data to be used in creating a custom treatment plan for each patient.

I love spending time off with my husband, Mark, and our large family. As a lifelong music lover, attending concerts and studying the harp bring me joy. Fitness, nutrition and growing vegetables year 'round are some of my favorite things.


Dental Hygienist

I graduated from Loyola University with a Bachelor of Science degree in biology and chemistry and later continued my education at Prairie State College to receive my degree in dental hygiene. I am passionate about educating patients and bringing awareness to the importance of oral health and its impact on systemic health, and I believe in providing compassionate and gentle care to all patients. I enjoy attending continuing education courses to be able to stay current with technology and the latest research to provide the highest quality care.

Outside the office, I enjoy gardening and group fitness classes, but most importantly, I enjoy spending time with my family.


Dental Assistant

Our patients are, far and away, the best part of my work. I love caring for whole families, from the toddlers through grandparents, and being part of their lives. This is a positive, fun place and our patients contribute to that atmosphere. I help patients during visits. I prepare them to see Dr. Jonker, explain what he’ll be doing, and answer questions. Then I offer chairside assistance, to make sure the doctor has everything needed while checking to make sure our patient is comfy.

I’m a longtime Naperville resident, having moved here in 1961 when it was still a small farming community. My husband John and I met in high school. I had two wonderful children who gave us four amazing grandkids. After raising my family, I took a small, part-time job here that has now become a 28 year long career. John and I share our home with two active Westies, Betty and Wilma, and two loud parrots. I enjoy gardening, as well as volunteering every Sunday with the USO at Midway airport.


Dental Assistant

Caring for patients has always been a passion of mine! This inspired me to pursue my certification in dental assisting from the College of DuPage. As a certified dental assistant, I enjoy getting to know my patients while collaborating with our team to provide the best dental care possible! Seeing the impact and the healthy, beautiful smiles we help create brings me so much joy!

Outside of work, I love spending time with my family, friends, and 5-year old chihuahua, Luna.
