Dr. Mackenzie King Platt
Dr. Mackenzie King Platt is more than just a dentist—she’s a passionate healthcare professional dedicated to creating confident, comfortable smiles for her patients in Lakeville, MN. A proud graduate of the University of Minnesota School of Dentistry, Dr. Platt has been transforming dental experiences since 2003.
Her journey in dentistry began with a simple yet powerful mission: to help people feel proud of their smiles and at ease during dental visits. In 2007, she took the bold step of opening Platt Dentistry from scratch, building a practice founded on compassion, skill, and genuine patient care. Her greatest joy comes from those moments when nervous patients leave her chair saying, "That was so easy"—a testament to her gentle approach and exceptional clinical care.
What truly sets Dr. Platt apart is her approach to both dentistry and team building. She leads a close-knit team that is more than just professional colleagues; they are genuine friends who enjoy each other’s company both in and out of the office. This warm, supportive environment translates directly into the patient experience, making dental visits something to look forward to rather than fear.
When she’s not caring for patients, Dr. Platt enjoys a rich life filled with outdoor adventures. She loves spending time with family on Wisconsin trails, enjoying side-by-side rides, and warming up by bonfires. A die-hard Gopher football fan, she’s always ready to cheer on her team (except when they’re playing the Badgers—then she hopes for a tie). Recently, she’s been challenging herself by learning to golf, adding another exciting chapter to her personal pursuits.

Claire
Dental Assistant
Claire joined the Platt Dentistry team in August 2025, but you could say her dental roots go back much further than that. In a fun twist of fate, Claire’s mother and Dr. Platt were actually classmates and friends in dental school. Since Claire was born while her mother was still in the program, she and Dr. Platt love to joke that they "attended dental school together!"
A graduate of St. Lawrence University in upstate New York, Claire was drawn to dentistry after shadowing in the field. She was struck by the unique opportunity dental professionals have to build genuine, lasting relationships with patients—a level of consistency and connection she found missing in other areas of healthcare.
As a Dental Assistant, Claire is known for her bright, approachable presence. Whether she is diving into the technical "ins and outs" of a complex procedure or jumping in to help her teammates, her goal is always to put patients at ease. She truly values the "family" atmosphere at the office, where laughter is a daily staple.
When she isn’t chatting with patients about their passions and life stories, Claire is almost certainly embracing the outdoors. She is an avid runner, mountain biker, and skier—covering both cross-country and alpine trails.
To unwind, she enjoys the focused calm of paint-by-number projects while catching up on her favorite podcasts.

First time going to Platt dentistry. Excellent service!! Jill did a great job cleaning my teeth. Both Jill and the Dr were pleasant and professional. Very convenient to make your appointment online. Gals at front desk were very nice. Will definitely go back.
