Penney – Patient Treatment Coordinator

Welcome to Yakima Smiles! We all look forward to meeting you. I am the first person you meet when you walk in our front door, and my mission is to make your appointment as easy and comfortable as possible. Excellent customer service is my specialty and I love the challenge of scheduling, coordinating insurance, and acting as the ambassador and concierge for one of the best dentists in Yakima.

I joined Yakima Smiles in 2006 and enjoy the challenging aspects of this practice, such as neuromuscular dentistry and sleep apnea treatment. I like working in a practice on the cutting edge of technology. I love the team atmosphere at Yakima Smiles, where we all work to provide our patients with the highest quality care. We have a lot of fun doing it, too! You will notice how professional we are and the big smiles on everyone’s face.

Outside of work, my husband of 23 years and I are super busy with our two boys, age 20 and 21. I love the outdoors and spending time with family and friends.

Jenna Landers – Registered Dental Assistant and Sleep Apnea/TMJ Patient Coordinator

Welcome to Yakima Smiles! I have had the privilege of working with Dr. Nathe for about nine years. I enjoy interacting with patients and providing excellent care. One of my greatest joys as an assistant is getting to know new patients and helping them feel at ease during their dental visits.

I believe we have an exceptional team and enjoy working with everyone! I appreciate Dr. Nathe’s concern for our patients’ overall health–not just their dental health. I am especially involved with patient care for TMJ problems and sleep apnea treatment with oral appliances, and absolutely LOVE this challenge. I thoroughly enjoy assisting Dr. Nathe, especially with our cosmetic and neuromuscular cases. To be able to witness the results from start to finish has been an incredibly rewarding part of my assisting career.

Outside of the office, I enjoy spending time with my husband Randy and our two boys, Logan and Cale. We love the outdoors and being surrounded by family and friends. Most of my free time is watching my boys play basketball and baseball.

Besides dentistry, I am find meaning in volunteering and love mountain climbing, golfing and traveling to exotic locations with my husband of five years.

Hello and welcome to Yakima Smiles! I am a graduate of Naches Valley high school class of 2007 and the Yakima Valley Technical Skills Center in 2007 with a certification in dental assisting. I have been a dental assistant for about eight years now. I love being a part of a team that is dynamic, fun, and where the patients are the focus. I recently joined the Yakima Smiles team in October 2016, and am very excited I found such an exceptional doctor and team to work with and am looking forward to growing with this practice.

Outside of work, I enjoy anything outdoors from camping, traveling, kayaking, snowboarding in the winter, and spending quality time with my family and friends. I am also a proud parent of an outgoing and hilarious 8-year-old boy named Zachary. 2019 has been an exciting year for me. I married the love of my life June 2019!

Beth Riel – Certified Dental Assistant and Expanded Function Dental Auxillary

Hello, I am blessed to be a part of this wonderful team at Yakima Smiles. Patient comfort and exceptional dental care is so important and Dr. Nathe is so amazing at both of these. I’ve been a dental assistant since 1993. I became certified in 2010 and then in 2011 I received my E.F.D.A. license. I love that at Yakima Smiles I’m able to expand my knowledge in dentistry.

I have been married for over 25 years and have one son and one daughter. I am a huge sports fan. In my spare time you’ll find me working in my yard or crocheting.

Rebecca, a registered dental hygienist

Rebecca Thomas – Registered Dental Hygienist

Welcome and thank you for choosing Yakima Smiles as your dental practice! I truly believe in the philosophy of Yakima Smiles and have been here since BEFORE Dr. Nathe joined the practice as owner. In fact, I worked with Dr. Nathe at the Yakima Valley Farm Worker’s Clinic and recruited him to come on board at Yakima Smiles! From the very beginning, I have admired Dr. Nathe’s ethical ideals to delivering the best dentistry possible including the all the latest in technology. He sets the highest standards and I have never seen him waiver from these goals. We have a great team who enjoy each other and working together which reflects in our patient care.

The connection between good oral health and overall health becomes more apparent daily. Our goal is to help our patients achieve and maintain optimal dental health. We have seen such positive life changing experiences and I love being a part of that.

My husband, Dale, and I have been married for 32 years. We have a daughter and three grandchildren to which we are devoted. Having family gatherings is our focus outside of work.

Breezy Byrne – Registered Dental Hygienist

I am thrilled to establish my career as a Dental Hygienist here at Yakima Smiles. I started working for Dr. Nathe in 2018, and I absolutely love being a part of a team that is patient care focused.

I am very passionate about helping people, and dental hygiene allows me to do just that. I value the importance of educating our patients on the link between oral and systemic health, and I strive to ensure that they feel comfortable by using a gentle touch while attending to detail for a thorough dental visit. It gives me great joy to experience the confidence attained by patients from improving their smile and overall health.

Outside of the office, I love to travel, stay active, and spend time with my family and friends. I also enjoy working as a skincare consultant with Rodan and Fields.

Anna – Dental Hygienist

I am excited to be a part of the incredible team at Yakima Smiles! What a great way to celebrate my 10th year in dental hygiene. I grew up in Naches and graduated from Yakima’s dental hygiene program in 2010. Since then, I’ve lived in California and Olympia, and I just recently returned to Naches to be closer to family. I love meeting new people and sharing what I know about dental health. I truly strive to provide the best experience possible by getting to know each patient that I serve and providing thoughtful, individualized care. Outside of work, I spend time with my husband and kids working and playing in nature whenever I can!
