Meet the Smile Shoppe Team


When you walk in the door at Smile Shoppe, we want you instantly to feel at home. We are happy to say we have not only the most talented team in the business, but the friendliest as well. We believe in building relationships with our patients, which is why we would like for you to get to know us before we have the opportunity to get to know you.

Dr. Amy Groeltz, Doctor of Dental Surgery, Fellow Academy of General Dentistry

Dr. Amy Groeltz, a graduate of Burlington High School, received her Bachelor’s degree from the University of Chicago in Biology and received her Doctor of Dental Surgery degree from the University of Iowa.  At the end of her final year in dental school, she received a scholarship to complete her extramural at a dental hospital in London.  This allowed her an excellent chance to see rare dental cases, an opportunity to observe a different health care system, and a chance to study with some incredible people.  She has also participated in dental mission trips to rural Jamaica and rural Costa Rica.  Currently, she is an active member of the American Dental Association, Iowa Dental Association, (g)nathos, local dental societies, and the Academy of General Dentistry.  She is a past president of the Prairie Valley Dental Society.  She has achieved Fellowship in the Academy of General Dentistry and has recently joined the faculty at the University of Iowa College of Dentistry as a Clinical Professor in the Family Dentistry Department.  She is married and has two daughters, one son, and a Labrador Retriever.

I enjoy…“having “dates” with my husband, making new discoveries with my children, and playing fetch with our Labrador Retriever.  I also enjoy traveling, photography, almost any outdoor sport, cooking, and reading.”

Something you may not know about me… “is that I love to travel but I have a knack for getting into crazy situations.  Some of my vacation "highlights" include getting stung multiple times by a smack of jellyfish, having my hand sliced by a mountain gorilla in Rwanda, hanging upside down from a bridge above the Zambezi, being charged by an angry bull elephant, bruising myself cliff jumping, getting shocked by a fence meant to contain chimpanzees, being bucked off then stepped on by a horse, and unintentionally swimming several class V whitewater rapids.  Since we have had children, though, vacations have become much tamer and most of the animals we see are in cages at a zoo.”


Rebecca Trimble, Registered Dental Hygienist

Rebecca was born in Chicago, Illinois.  She then moved to Fort Madison, IA and graduated from Fort Madison High School in 1999.  She attended SCC for two years to earn her AA degree and then continued her studies at University of Northern Iowa in Cedar Falls for one year, studying Elementary Education.  After deciding to take a different career path and enter the dental field, she then attended Carl Sandburg College of Dental Hygiene in Galesburg, IL and became a Registered Dental Hygienist in May of 2007.  Rebecca joined the Smile Shoppe team shortly after its opening as its first and only hygienist.  She has two sons and one daughter.

I enjoy… “spending time with my two boys, and baby girl.  Also, I enjoy bowling, going for walks with my children, and baking.”

Something you may not know about me…  “I have been bowling since I was 6 years old and had always dreamed of being a pro bowler.  I was bowler of the year at Fun City in 2010.”


Jenny Johnston, Registered Dental Assistant

Jenny grew up near Shueyville and is a graduate of Solon High School.  She graduated from Kirkwood Community College in 1994 with an Associate degree in Dental Assisting.  She lived in Wisconsin for a couple years but missed Iowa's "mild winters" and returned her home state.  She is married with two children.  She joined the Smile Shoppe team in 2010.

I enjoy… “making jewelry, baking, working in my flower bed, and camping.”

Something you may not know about me… “is that I like to fish.  Something my husband doesn’t know about me is that I know how to clean them.” 


Erin Ross, Dental Receptionist and Registered Dental Hygienist

Erin is the newest member of the Smile Shoppe team, joining us in 2018.  Erin grew up near Denmark, Iowa and graduated from Fort Madison High School in 2006.  She furthered her education at Southeastern Community College where she earned her AA degree.  Erin then moved to Cedar Rapids, Iowa and attended Kirkwood Community College and graduated as a Registered Dental Hygienist.

I enjoy... kayaking, camping, going to concerts, playing with my dog (Willow), cooking, baking, and Sunday dinners with my parents and sister.

Something you may not know about me... is that I have volunteered in different countries.  In San Miguel de Allende, Mexico, I volunteered at a wonderful daycare that provided food, education, and a safe place for children in greatest need.  I was supposed to stay for two weeks but fell in love with the kids, so I changed my flight and stayed for six weeks!  Later, while attending Kirkwood Community College, my dental hygiene class embarked on an amazing journey to Antigua, Guatemala.  We volunteered with an incredible organization which provides education and care for abandoned, malnourished, or orphaned children.  Our team built six houses (by hand, no power tools!) for families in need.  This was an experience of a lifetime for me and my team.  I plan to continue to travel the world and spread joy.


Martin Joyce, Office Manager and Accountant

Martin is a native of Boston, Massachusetts.  After graduating from Boston College High School, he moved to Chicago to attend The University of Chicago where he received a B.A. in Economics.  He has worked for a number of financial firms and also received an M.B.A. in accounting and finance from the University of Chicago Booth School of Business.  Martin manages the business, the accounting, and pretty much all other behind the scenes aspects of Smile Shoppe.  He is also a Licensed Dental Assistant.  He and his wife have three wonderful children.

I enjoy… “spending time reading, watching the Red Sox, and spending time with my family." 

Something you may not know about me… “is that I have lived in five states from coast to coast in my life:  Massachusetts, Illinois, California, Ohio, and Iowa.”


Our Outdoor Pets

On our hillside resides a groundhog family.  We think they are quite cute and they have been a great source of entertainment for our youngest patients (and those young at heart.)  This spring three new baby groundhogs appeared and five appeared last year.  We have affectionately named the patriarch (you will recognize him as the old guy without a tail) Philling.
