Office Coordinator

Welcome to our practice! Finding ways to help people smile is my priority. Building your confidence so that you can share your smile is my goal! My role is to help resolve concerns and make your visits positive. I am happy to answer your questions and plan for appointments. It is important to me that each of you enjoy a feeling of ease and confidence in our office. I bring over 15 years of experience in the dental field and am thrilled to be a part of the Spring Valley Dental Care team. I appreciate how positive the environment is here. We all work extremely well together to provide the best service for you. Our staff is very warm and inviting. I love the positive energy felt by everyone and I really appreciate the attentive care our doctors and team strive to provide, as individuals and collectively, to each patient.

My husband and I have 2 children. I love doing all things outdoorsy with my family. You will often find me out enjoying our boat on the lake and traveling. I also enjoy doing crafts and watching movies with my children. Thank you for the opportunity to serve your oral health care needs.



Patient Care Coordinator

I began my dental career over 30 years ago as a Dental Assistant. I am the Patient Care Coordinator here at Spring Valley Dental Care and I am happy to answer any questions you may have to help resolve your concerns, and make your visits pleasant and positive! I love the attentive care Dr. McGrane, and our team strives to provide our patients.

In my free time, I love treasure hunting. You can also find me running, playing tennis and spending time with my daughter and son. I also have my furry children, Willy and Sylvester.



Registered Dental Assistant with Expanded Functions Certification

Hello, and welcome! My name is Nikki, and I have been working with Dr. McGrane for over 20 years. I enjoy working with our patients, and I always make an extra effort to make each patient feel welcome when visiting our practice. I understand that some of our patients experience anxiety. One of my goals is to listen to their concerns and do everything I can to ease their nervousness and ensure that they have a positive experience. Making my patients feel cared for is important to me. One of my favorite things about working in dentistry is talking to our patients about their own lives and getting to hear about their experiences and accomplishments. Working chairside with Dr. McGrane is great. He encourages our entire team to continue growing and learning, and is always bringing new technology into the practice.

Outside of the practice, I am a busy mother of two girls, Cora and Grace and we have one dog named Montana. When I have leisure time, I enjoy biking, taking care of our yard, scrapbooking, and driving my kids from one activity to the next. I also enjoy taking trips with my family.


Registered Dental Hygienist

Hello, my name is Dana and I am one of Dr. McGrane's dental hygienists. I grew up in Edgewood, Iowa and settled in Cedar Rapids after college. I have been in the dental field for 22 years after receiving my dental assisting degree in 1991 from Kirkwood Community College. I worked in the field for a few years before going on to receive my dental hygiene degree from Hawkeye Community College in 1998. My favorite part of working in dentistry is getting to know all sorts of people and building relationships with them.

In my free time, I enjoy getting out and trying new things! I enjoy spending time with my two awesome sons. We enjoy doing all water activities such as boating, fishing and swimming. I also enjoy reading, walking and watching the Hawkeyes!



Registered Dental Assistant

Hi, my name is Elgean. I am a dental assistant here at Spring Valley Dental Care. I joined Dr. McGrane and his staff in the summer of 2017. I had worked for my previous dentist for thirty years and was nervous about this next chapter in my life. Everyone on the Spring Valley Dental Care team has been very welcoming to me and it has not taken me long to feel at home. I know you will feel the same when you join our practice as a patient. We strive to provide our patients with an atmosphere where you will feel at ease and confident in the care that you receive.

In my free time I enjoy running, biking, being outdoors and taking road trips. My husband and I live in Hiawatha. We have four children and two grandchildren, all who keep us very busy.



Expanded Functions Dental Assistant

Welcome to Spring Valley Dental Care! I enjoy helping out in all areas of the office. Your smiles are my goal and my passion. I have been an Expanded Functions Dental Assistant for over 6 years, and I have been working at Spring Valley Dental Care since I graduated Kirkwood's Dental Assisting program. I am positive, and easy going. I may coordinate your dental treatment, make digital photos, or scans of your mouth. When you are proud of your smile, so are we!



Dental Hygienist

Hi, I’m Jerri. My main role in the office is to provide our patients with gum disease treatment, routine cleaning, and placing sealants for children. I have worked as a hygienist since 1991, and have been happily working with our dental team since 2001. I feel very satisfied to know that I am helping to improve our patient’s smiles, and their health by providing high quality dental care. I am a native of Iowa and have lived in Marion since 1996. When I’m not in the office I enjoy reading, playing cards and darts, and hanging out with my kids.
