Great Lakes Childern's Dental in Duluth MN


Dr. Rami Guirguis, DDS, MS
Practice Limited to Pediatric Dentistry

Dr. Rami attended Bloomington Jefferson High School in Bloomington, MN and pursued his undergraduate and dental studies at the University of Minnesota-Minneapolis. During his third and fourth years of dental school, Dr. Rami realized how much he enjoyed his rotations in the pediatric dental clinic and decided to pursue specialization in the field of Pediatric Dentistry. He spent an additional 2 years of post-graduate training at the University of Minnesota School of Pediatric Dentistry where he earned his Master’s Degree, won a National Research Award, and obtained his specialization certification in Pediatric Dentistry. Upon graduation, Dr. Rami worked in various clinics throughout the Twin Cities and Duluth before opening his Duluth practice in 2001. He works alongside his wife, Dr. Susan Guirguis, a general dentist. Together they have two sons – Alexander and Christian. Dr. Rami enjoys spending his free time with the boys, travelling, and enjoying the lakes and outdoors in the summer time. He also enjoys his time in the Twin Cities catching up with family and friends.

Dr. Susan Guirguis, DDS

General Dentistry

Dr. Susan graduated from Jefferson High School in Alexandria, MN. She attended the College of St. Benedict/St. John’s University where she obtained her degree in biology. She further studied cytology at Associated Pathologist’s Laboratories in Las Vegas and worked as a cytotechnologist at Hennepin County Medical Center in Minneapolis while Dr. Rami was finishing his studies in Pediatric Dentistry. Once Dr. Rami completed his studies, they switched places and Dr. Susan went on to study dentistry at the University of Minnesota - Minneapolis. Shortly after graduating in 2001, she joined her husband in Duluth to start their practice. Once settled into their new office, they started their family and settled into “life up north!” Dr. Susan remains busy with whatever her boys are into at the time – this includes a lot of school work and running around to different activities after work. She also has two other “furry babies” at home: their mixed breed rescue dogs Dexter and Scooter.  Along with the boys, they keep her busy too!
