  • Nancy Thomas
    Office Manager


    I have lived in Lebanon, Oregon since the early 70’s. After graduating from Lebanon Union High School, I went to LBCC where I became a Dental Assistant and have been working for Dr. Clark off and on since 1989.

    I have 3+ kids and 2 grandsons and I enjoy spending time with them all. Plus have a love for reading and sewing.

  • Alice Stewart
    Appointment Manager


    My name is Alice and I have worked for Dr. Clark since 1987. I have met some truly wonderful people working here. I consider many of them my friends. I have three amazing grandchildren and I spend as much time with them as I can. Not much time for hobbies, as grandchildren keep me extremely busy.  I am living the dream.

  • Heather Koffler
    Dental Assistant & Sterilization Tech

    Hi, my name is Heather. I was born and raised here in the Lebanon area. I have 3 sons and 2 grandchildren.  I enjoy riding motorcycles, hiking, painting, taking care of my 3 large dogs, and spending time with my loved ones. 

    I went to LBCC to obtain my Dental Assisting Certification, EFDA, and EFODA.  I have been with Dr. Clark and the team for a few years now.  As a Clinic Coordinator, I have many tasks such as ensuring a smooth flow in the clinic, ordering supplies, and taking inventory as well as chair side assisting at times.

  • Lecia Elverfeld
    Insurance Benefit and Eligibility Specialist

    My name is Lecia, and I’ve been working as Insurance Benefit and Eligibility Specialist for Dr. Clark since October 2019. 

    It’s been such a pleasure working with fellow employees and an employer who values not only our patients but also values each other.  I have three grown children who I love spending my time with.  I enjoy fishing, rockhounding, kayaking, gardening, and most anything outdoors. 

  • Dunia Hamdan

    My name is Dunia and I have been a Registered Dental Assistant since 2017 when I graduated from Cuyahoga Valley Career Center in Ohio.  I moved here to Oregon so that I could live with my boyfriend. I love to spend time outdoors and do woodburning art.   My goal as a Dental assistant is to make patients feel comfortable and at ease when they come to the dentist.
