Meet The Team


Office Coordinator/Assistant

I have enjoyed working in the field of dentistry since 1986. I joined Dr. Engen’s practice in 1988 and I feel very fortunate to be involved with such a caring and professional group.

I help run the day to day front office including scheduling, patient treatment coordinating and communication from our office to our referring doctors. I am also a surgical and orthodontic assistant which enables me to work one on one with the patients and really get to know them. In addition, I coordinate continuing education programs our doctor’s host including the Spokane Study Club. Being part of a team which improves smiles, betters patient’s oral health and boosts their confidence is very rewarding!

I enjoy spending time with my husband, Alan and our son Joey (2006). We love to snow ski, camping and walk the beaches on the Oregon Coast. I treasure my time with family and friends. I have lived in Spokane my whole life.


Receptionist/Scheduling Coordinator

My career in dentistry began when I joined the Engen and Hahn dental family in 2010 as sterilization assistant. Now as the receptionist, every day I have the honor of welcoming amazing people into our practice, scheduling their appointments, answering questions and coordinating their treatment with our referring doctors. I have the experience and knowledge of both the back and front office procedures and I love that!

What I appreciate most about our office is the individual care we give to each person who walks through our door. I’m very proud to be a team member in a practice that provides a warm and inviting atmosphere, state of the art dental treatment, impeccable professionalism, education, humor and last but not least, group camaraderie. It doesn’t get much better than that! Every day is new and different from the last. I truly enjoy visiting and getting to know our patients.

I earned my Bachelor’s Degree from Washington State University. My family is very important to me. My husband George and I have been married since 1992 and have two amazing boys, Tyler (1994) and Connor (1997) who are both third generation Cougs! My free time is spent with my family and our pet dog, and outdoor activities like hiking and boating.


Surgical/Orthodontic Assistant

I am a graduate of Spokane Community College where I received my Dental Assisting Degree. I began working for Drs. Engen and Hahn in 2002.

I am both a surgical and orthodontic assistant. I love the variety of my profession! I assist in cases from placing dental implants to placing braces and I order all the dental supplies for the office. I attend continuing education lectures on a regular basis and help coordinate many of the lectures Dr. Engen hosts such as the Inland Northwest Dental Hygiene Study Club and the Peer Practicum Study Club. I enjoy teaching our patients the importance of a lifelong commitment to good oral hygiene to keeping their mouths healthy. It is very rewarding to help restore someone’s smile and confidence! I am proud to work at an office where everyone takes such pride in their job and is so caring. We all truly want the very best result for each and every patient!

I enjoy spending time with my husband Jason and our children Cloe (2003), Layla (2009) and Cooper (2014). They keep us busy with soccer games and cheer. We spend a lot of time outdoors with our extended families barbequing, camping and boating on the lakes and rivers nearby.


Surgical/Orthodontic Assistant

I graduated from Spokane Community College where I received my degree in Dental Assisting in June 2005. I was lucky enough to be hired at this office right out of school!

I enjoy working with children and adults so being in a dual specialty office gives me the opportunity to work with both! I have found working in the dental field to be very rewarding. I have enjoyed helping our patients improve their oral health through replacing missing teeth with dental implants, regenerating lost bone and tissue as well as straighten teeth.

I was born in San Diego, CA. I was raised on the East Coast and moved to Spokane in 1999. I enjoy spending time with my husband Matt and two kids Alexia (2002) and Mason (2007). We enjoy the outdoors and are active in our child’s activities including BMX racing!


Business Manager

I went to college at EWU and started my dental career as a dental assistant in 1999. I found I loved helping patients with their appointments, working with insurance to maximize dental benefits and coordinating financial arrangements to help each patient achieve their individual goals.

I joined the Engen/Hahn dental team in 2013 as part of the financial and treatment coordinating team. In January 2017 I became the business manager. It has been a fun journey being part of the business side of the dental office.

Drs. Engen and Hahn have a wonderful and amazing team that I’m proud to be a part of! I enjoy seeing how our doctors are able to help change patient’s smiles and lives.

I enjoy spending time with my husband Monte and our kiddos, Cheyanne (1996), Cleo (2010) and MJ (2013). I also like spending time quilting, reading, skiing, and time at our family’s place at Whidbey Island.


Treatment and Financial Coordinator

I have been in the dental industry for the past 22 years. I started out as an assistant and then moved to the business office where I did the scheduling and the finances. I enjoy all facets of the business side of dentistry, but am most passionate about helping the patients feel comfortable and answering any questions or concerns tat they might have.

I feel blessed to have joined Drs. Engen and Hahn’s office in 2017. They all take pride in the patient care and are all so professional. I’m truly grateful to be part of such a fantastic team.

I live on a small farm where I enjoy my garden and all my animals. I have two loving large breed dogs that are my children, three cool cats, a special needs horse (mostly blind but very healthy!), many chickens and six cows. My husband and I also raise and bale our own hay. The farm keeps us very busy. When the opportunities arise, you will find us camping on the river, hiking, kayaking and enjoying the beauty and solitude of the mountains.



Yvonne received her Bachelor of Science Degree in Dental Hygiene from Eastern Washington University in 2007 and her Master of Science in Dental Hygiene from EWU in 2013. She has also received specialty training in laser use in dental hygiene therapy. Yvonne served as a clinical instructor at EWU in the pain control, restorative dentistry and clinical hygiene departments. She is an active member of the American Dental Hygiene Association, American Dental Education Association, Washington State Dental
Hygiene Association and the Inland Northwest Dental Hygiene Study Club.

Yvonne has experience in both general dentistry and specialty periodontal/orthodontic practices and takes pride in the focused care she provides. “My focus is primarily on the patient’s periodontal health, and being a part of a specialty team at Drs. Engen and Hahn, allows me to concentrate on being a prevention specialist for each and every patient.”

Yvonne joined Drs. Engen and Hahn in 2013.  She is very blessed and thankful to be part of the team. Outside of the office, Yvonne enjoys running, reading, baseball and baking anything with chocolate. She and her husband Cory have four children, Brittany, Emily, Connor and Andrew.



I worked as a Dental Assistant for six years before graduating from University of Southern California in 1995 with a BS degree in Dental Hygiene, and stayed and taught at the dental hygiene clinic.

I belong to The Inland Northwest Dental Hygiene Study Club, the largest hygiene study club in the nation, Dr. Engen is the co-founder. Working with Drs. Engen and Hahn is a privilege and a pleasure. I feel very fortunate to work with a team of people who truly care for each and every patient, people of good character, who conduct themselves with the highest level of integrity.

I love what I do! It is important for me to have interaction with every patient and have them come away knowing that I truly care, and want to provide them the best experience in dentistry we have to offer.

I am extremely blessed to have the love and support of my family. My husband and I have been together for twenty eight years. We have two beautiful daughters, who are very busy with their studies and sporting events. We recently added a new family member, a Maltese puppy, who brings us much joy. I treasure time with family and friends. I love to swim, bike and run.


Patient Care Coodinator

I graduated from Spokane Community College where I received my dental assisting certificate in 2006. I worked as an assistant and then as an insurance coordinator in a general practice for twelve years. I was beyond blessed to have joined the professional team of Drs. Engen and Hahn in 2019. Here I work in the business office coordinating patient care and helping with their insurance benefits. I enjoy working with each individual to financially accomplish their dental goals with payment options they are comfortable with. I look forward to a lifelong career with this amazing and talented group that I am so proud to be a part of.

I was born in Spokane but grew up in Elk, WA. Dave and I enjoy spending time with our chocolate lab fur babies, and most importantly the love of our life, our first born child who we brought into this world in 2018, Shedley. We are very compassionate about the outdoors: hunting, shed hunting (how our son got his name), fishing, hiking, camping all things outdoors we love it and do it.


Sterilization Assistant

I graduated from high school in 2016 and joined the Engen/Hahn team two months later. I have lots of responsibilities…and I love every second of it! I take x-rays, sterilize instruments and co-assist in implant surgeries. I learn something new every single day! I’m grateful to work with such amazing people!

I will be starting night classes fall of 2017 at Spokane Falls Community College, where I will earn my AA degree and then transfer to Eastern Washington University to hopefully get into the dental hygiene program.

I spend lots of time with my friends and family. I love to ski, hike and play soccer any chance I get!
