Meet Dr. Oppenhuizen

Read More about Dr. Oppenhuizen

Dr. Gregory Oppenhuizen leads West Michigan’s most established orthodontic practice. Originally from Grand Rapids, Michigan, Dr. Oppenhuizen is a graduate of Calvin College, the University of Michigan School of Dentistry, and Indiana University where he received his Specialty Certification in Orthodontics and Master’s Degree in Dentistry.

Recognized for his numerous contributions in the dental and orthodontic associations in which he serves and for his community work, Dr. Oppenhuizen is a Diplomate of The American Board of Orthodontics, and has been nominated by his peers as a Fellow of the American College of Dentists and the Pierre Fauchard Academy. He has also served as President of the Great Lakes Association of Orthodontists and has been actively involved in multiple levels of governance of the American Association of Orthodontists.

Dr Oppenhuizen is also a member of the Angle Society (Midwest), a rare accomplishment achieved by only a handful of orthodontists worldwide. To become a member, you must be board certified, peer nominated, submit further board qualified completed cases (just like the board examination), submit and complete numerous active treatment cases for rigorous peer review, and original peer-reviewed research. 

Dr. Oppenhuizen brings a unique background and interest in the arts to his practice of orthodontics, including a love of music and horticulture. And when Dr. Oppenhuizen isn’t serving patients at the office or caring for plants in his garden, you’re likely to find him swimming or scuba diving. Be sure to ask him about his love of underwater photography and how his photos showed up in a Russian diving magazine! Take a look at some of his underwater photography at the link above.
