Associate Optometrist

Dr. Alyssa Richard, a Minnesota native, earned her Bachelor of Science degree in Biology at Hamline University in St Paul MN where she also competed on their dance team. She then moved to Pikeville, Kentucky and graduated from the Kentucky College of Optometry.

Living in the Appalachian (pronounced “app uh LATCH in” as she very quickly learned) mountains allowed her to gain valuable experience in rural health care where she learned to manage many types of patients and conditions. Through this, she found a passion for primary and pediatric eye care. She strongly believes that proper development of the visual system is crucial in setting children up for success. Dr. Richard is a current member of the American Optometric Association and the Minnesota Optometric Association. Dr. Richard grew up in Monticello, MN where she is now an assistant coach for their high school dance team.

In her free time she enjoys spending time with family, friends and her cat Beans. She enjoys fishing in both the summer and winter months, and takes advantage of any chance she gets to spend a day on the water. Being from the State of Hockey she is, of course, a Wild fan and tries to get to as many games as possible during the season.

Outside of her professional life, Dr. Athmann enjoys spending time in the great outdoors with her husband, Austin. During the summer months, you can likely find them on the lake, the golf course, or cruising the trails in a RZR, but as soon as the snow starts to fall they take every opportunity they can get to escape out west and hit the slopes.

Director of Pediatric Services

Fellow, American Academy of Optometry

Clinical Investigator, Pediatric Eye Disease Investigator Group (PEDIG)

Advanced Residency Training in Pediatric Specialty Care

Adjunct Professor of Optometry

With advanced training and experience in pediatric specialty care, it is a joy and privilege to serve the majority of infants and children at PineCone Vision Center. My passion for this specialty is rooted in advocating on behalf of those who are often unable to articulate their own visual experience. I believe it is essential, therefore, to be grounded in evidence-based principles when making treatment decisions for these little ones.

While I enjoy seeing children of all ages for their comprehensive eye care, I am especially interested in managing amblyopia, eye misalignment, and optic disc elevation, as well as monitoring for ocular complications associated with systemic disorders such as intracranial hypertension, juvenile idiopathic arthritis, and genetic syndromes.

As an Idaho native, I grew up in the Northwest and received my Bachelor’s degree from Seattle Pacific University and went on to Pacific University of Oregon to obtain both my Doctorate of Optometry and Master of Education in Visual Function and Learning. Following graduation, I joined a pediatric optometry practice in the Seattle area for additional experience working exclusively with kids. I then moved to Denver to complete a residency program in Pediatric Specialty Care at Children’s Hospital Colorado for more advanced training in pediatric ocular disease and genetic syndromes affecting the eye.

My wife Nancy, who is also an optometrist, grew up on a dairy farm near Watkins and took it upon herself to introduce me to sub-zero windchills, long-O accents, and the Schnitzelbank tradition. When Nancy and I are not talking about eyes, we enjoy hanging out with our kids Jett, Ezra, and Blaise,  getting involved in our local church community, and challenging each other to CrossFit workouts.
