Shakopee, MN dentist


Dr. Christianson graduated from the University of Minnesota School of Dentistry in 2008, after completing his undergraduate studies at the University of Minnesota Duluth.

Continuing education is a top priority, as he strives to stay on the cutting edge of dentistry so that he can provide the best dental care possible.

Dr. Christianson is an active member in the Southside Comprehensive Study Club and also participates in the “Give Kids a Smile” program. In his spare time, he enjoys spending time with his wife and four small children.

As an outdoor enthusiast, that’s where he can be found when he is not at the office. Dr. Christianson also enjoys most sports, and is a high school football official in the fall.

Austin Ostrander


Dr. Ostrander grew up in Glenwood, MN and attended the University of St.Thomas and graduated with a degree in Biology. He completed his dental school education at the University of Minnesota. 

Dentistry is an incredibly rewarding profession. Dr. Ostrander prides himself on clear communication with patients to understand their goals and make sure they feel heard so we can work together to achieve a trusting and comfortable relationship. 

It is important to Dr. Ostrander to stay up-to-date with the most current techniques and technology through his association with several continuing education societies including the ADA, AGD, and attending the Star of the North Conventions. 

When I am not in the office, I enjoy playing sports like golf, softball, pickleball, and basketball. During the summers I spend as much time on a boat as I can!

Nathan Hanson


Dr. Hanson is originally from Stillwater, MN.  He graduated from Gustavus Adolphus College with a degree in Biology and a minor French.  After a gap year in Philadelphia, PA, he completed his dental school education at the University of Minnesota.

Dr. Hanson’s first interest in dentistry came from a desire to work with his hands but fell in love with dentistry through interaction with patients.

Dr. Hanson stays up-to-date with current dental practices through continuing education. He loves to stay active in his community through volunteering at The Special Olympics and other community events.

Dr. Hanson can be found wearing brightly colored scrubs and loves to laugh at work!

Aside from dentistry, Dr. Hanson enjoys camping, hiking, anything involving lake, and endurance sports.
