Dr. Diekema has been practicing Optometry since 2016. She says she likes talking with her patients to create a plan that provides them with both clear vision and healthy eyes. Dr. Diekema says the fact that no two pairs of eyes are the same is what keeps her job interesting.

Dr. Michael Kruglet


Dr. Michael Kruglet is seasoned Optiometrist with more than 10 years of experience caring for eyes of all ages. He is certified in scleral, corneal scleral and orthokeratology lenses as well as diagnosing and treating dry eye. Dr. Kruglet in his own words: "We all have to work and what better way to spend your day then by helping others. We all know someone, or have had a family member lose vision and it can be debilitating. Growing up I remember watching my grandmother struggle while playing her favorite card game due to macular degeneration and that's when I knew I wanted to go into the eye field. Helping someone see clearer today than what he or she saw yesterday is what I enjoy most. Watching someone light up with excitement when they put on their glasses or contacts for the first time makes me proud to be an optometrist. Also, the wonderful relationships I've formed with my patients over the years is a close second." Dr. Kruglet is a graduate of Creighton University.

Dr. Michael Morovati

Dr. Michael Morovati received his Doctor of Optometry from the University of Alabama at Birmingham in 2003. He also holds a Bachelor of Science in Biology from Troy University.

One of the most rewarding parts of being an Optometrist, as explained by Dr. Morovati, is seeing the smile on his patients’ faces after picking up their glasses for the first time.
