Doctors & Staff

Meet the experienced and friendly doctors and staff who make Lake Country Eye Care a proud provider of vision care products and services in Hartland.

Dr. Amber Dentz, O.D.

I have been practicing optometry in the lake country area since I graduated from Optometry School in 2001.  I grew up in East Troy, WI and graduated Valedictorian of my class in 1992.  I then attended The University of Wisconsin-Madison an received my Bachelor of Science in 1996. GO BADGERS!!! Instead of heading right to graduate school, I took a year off and moved to Portland, OR where I worked for an optometrist and explored up and down the west coast!  In 1997 I started Optometry School at Indiana University-Bloomington and graduated with high honors in 2001.  During school I was chosen to be an assistant instructor for a number of classes, and received awards in academics and contact lens expertise.

I am a proud member of the American Optometric Association and the Wisconsin Optometric Association.  I have served on the Wisconsin Optometric Association Board of Directors since 2009, I am currently the Treasurer.  In 2010 I was extremely honored to receive the WOA Young Optometrist of the Year award from my peers!  I enjoy volunteer work and annually try to participate in a program that performs vision screenings at Special Olympics events, as well as donating eye exams at Walker’s Point Community Clinic in Milwaukee.  I also love to volunteer when I can at my children’s school in Hartland and sponsor programs there as well.

I live in Hartland with my husband, Aaron; two children, Lauren and Brody; and two dogs. I like to spend time skiing, golfing, walking, and yoga. I enjoy traveling and have been to many exotic places such as Panama, India, Singapore, Thailand, and Europe.  I especially  love spending time with my wonderful family and friends!
