Meet The Team

Dr. Irene Renieris

General Dentist

Dr. Irene Renieris completed her undergraduate degree in Communications from The University of Michigan. She then went on to Indiana University School of Dentistry where she graduated with her dental degree. After dental school, Dr. Renieris returned to her home state of Michigan to complete a one year general practice residency at The University of Michigan Hospital in Ann Arbor.

Dr. Renieris couldn't have chosen the most perfect career for her personality. She loves to engage with patients and tries to make every visit as painless as possible. When she's not in the office, she's enjoying time with her husband Eric, and two young sons, Apollo and Atlas. Dr. Renieris recently moved to the Lincoln Square neighborhood and enjoys being within walking distance of the office.
