We feel fortunate to be given the opportunity to improve our patients’ confidence and self-esteem by giving them beautiful smiles through high-quality orthodontic care. Orthodontics is not just our job, it’s also our passion. Our patients’ happiness with their smiles is something that will last for a lifetime and we are so blessed that we have the chance to help them achieve all of their smile goals.

Our office and team have grown over the years to meet the changing needs of our patients. You will find your time here with us is comfortable and fun. Most importantly, achieving your goals will be rewarding and the benefits of a healthy smile will last you a lifetime.

Dr. Eric Hannapel


I earned my Doctorate of Dental Surgery at the University of Michigan in 1992 and completed a general practice residency at the University of Michigan Medical Center in 1993. I also attended U of M for my specialty education, completing my master’s degree in orthodontics in 1996. I started my orthodontic practice in 1996 and begin each day with my personal mission statement to welcome staff and patients into my office with honesty, commitment, and a “do what it takes” attitude every day.

I believe that continuing to invest in the education of myself and my team has helped us serve our patient families in a very special way. I take over 40 hours of continuing education every year to stay on top of the advances in my profession, including technology and research. I also work as an adjunct clinical assistant professor at the University of Michigan School of Dentistry. I love being able to share my knowledge and teach the orthodontists of the future!

Outside the Office

I have lived all my life in the surrounding Grand Rapids area and am pleased to raise my family here and to provide beautiful, healthy smiles in the area where I grew up. When I am not creating smiles, I enjoy snow skiing, biking, wakeboarding, and wave surfing. I also love traveling with my wife (Dr. Beth) and our four children: Madison, Daniel, Aiden, and Caroline.

Dr. Sonni Pellillo


I obtained a degree in chemistry from Vanderbilt University in 2009. After that, I returned to my home state, West Virginia, and earned my Doctorate of Dental Surgery. From there, I attended residency in South Florida at Nova Southeastern University, where I received my master’s and a certificate in orthodontics and dentofacial orthopedics. I practiced in Greenville, SC, for two and a half years before moving to West Michigan to join this dental practice in June 2018!

I married my husband, Brian Harris—a Michigan native—in 2015. We have a daughter (Reva) and a puppy (Fenton). In our spare time, we love to be on the lake and enjoy traveling, biking, hiking, and wake-surfing. We are excited to be back in West Michigan to be closer to friends and family.
