Lynn Castro, R.D.H.

Dr. Mannering graduated from Northwestern Dental School in 1980 and has been in private practice in Chicago for over 30 years. She is committed to continuing education.  After completing the curriculum at the Pankey Institute, she was invited to join the visiting faculty and has continued to teach there for the last 14 years.  In addition to her work at the Pankey Institute, Dr. Mannering has also studied with the Dawson and Spear Centers for continuing education. Currently, Dr. Mannering is enrolled in a one-year orofacial pain program to better serve patients who have TMD, sleep disorders, and other types of orofacial pain.

Recently, Dr. Mannering presented at the American Dental Association National meeting on occlusion and at the Academy of General Dentistry on occlusion and aesthetics.  Her leadership in dentistry is realized in the many study clubs she has initiated and continues to facilitate in the United States and abroad.


As a preventative oral healthcare specialist since 1995, Lynn's combined interest in health sciences and her interpersonal skills made dental hygiene her natural career path.  Lynn feels fortunate to have worked with Dr. Mannering's practice since 2007 and enjoys the team-oriented approach to treatment, the value placed on patient relationships, and the consistently beautiful dentistry that is the direct result of Dr. Mannering's efforts.  She appreciates working in an environment where the team values preventative oral healthcare as an important component of whole body health.  She is committed to providing the highest standard of patient care.

Having been a frequent visitor at the dentist’s office during childhood, Stacy came to admire the care and effort dentists put forth to help their patients achieve good oral health. Stacy was grateful for the opportunity to intern and learn from the Mannering Dental team. Her goal is to work with patients to make sure they are happy and comfortable.

As a recent graduate of the University of Illinois at Urbana-Champaign, her degree and undergraduate research in food science and human nutrition has allowed her to communicate and connect to individuals from diverse backgrounds.

With her interest in healthcare and background in hospitality (since being raised in the Water Park Capitol of the World), her goal is to become a provider that offers preventative services while running her own company, which pointed her in the direction of dentistry.  Her bachelors degree in Rehabilitation Psychology has molded her into a pre-professional that communicates with and appreciates individuals with all abilities. Ardita plans to attend dental school in the Midwest.  She appreciates Dr. Mannering and her team for their willingness and patience to help everyone succeed, including patients.


“Having the opportunity to take part in an internship with Dr. Mannering helped me grow as both a future dental professional and as an individual.  I was able to learn and develop hands-on skills that will help me as a dental student next year, in addition to building meaningful and lasting relationships with patients.  I was also exposed to many of the unique challenges facing private practices today and feel prepared to make my own business decisions after graduating from dental school.”

Dental Intern

Applications for the 2019-2020 internship are currently CLOSED.

Our practice provides promising pre-dental students with the opportunity to gain experience in the lab, assist with procedures, manage the sterilization process, and learn the business side of dentistry. Here is what a previous intern has to say about his experience:

"The internship has given me a much better understanding of the field and really helped me in my interviews. You will get hands-on experience in the lab and by assisting the doctor. You will also be exposed to many of the unique challenges of a private practice and will know what to expect upon graduation from dental school."

The internship program begins in July and lasts for one year. The position requires a full-time commitment Monday through Thursday. We look for someone who is seriously interested in dental school as expressed by either having already completed the Dental Admission Test or by having it scheduled in the coming months.
