Dr. John Mergen has been providing happy smiles to patients in Johnson County and the surrounding areas since 1997. He believes in creating a fun and relaxed atmosphere where patients always feel welcome and comfortable. So when you walk through our doors, you’ll feel like you’re in a warm, inviting coffee shop with fresh-baked cookies, hot cocoa, donuts, and monthly fun giveaways. We specifically designed our offices to not look like an office, but a place that’s comfortable and even spa-like.

Dr. Mergen is a second generation orthodontist who watched his father build patients’ self-esteem by improving their smiles. He began making retainers for his father’s practice, which piqued his interest further in orthodontics. He realized he wanted to follow in his father’s footsteps and committed to an accelerated 3-year honors program at the University of Iowa College of Dentistry. In 1995, he graduated with honors, graduating 2nd in his class of 87. Upon graduation, Dr. Mergen accepted 1 of 5 spots into the top orthodontic graduate program in the country at the University of Iowa College of Dentistry, where he earned his master’s degree in 1997.

His academic awards include:

  • Omicron Kappa Upsilon Honor Dental Society
