His dental practice and team share a patient-centered and comprehensive approach to maintaining patients’ oral health and continue to provide dental care to the highest standards.“I love what I do. Dentistry is the perfect blend of art and science for me. I thrive when I am challenged most and take great pride in educating patients on their oral health needs. The trust each patient places in me is taken very seriously and I take pride in every procedure I commence.”

Halle Daubner, Front Office Halle Daubner, Front Office
Hi! I’m so happy to have joined the Koett/Olson/Small dental family in 2018. I grew up on the East coast and moved to Lake Tahoe to study Sustainability at Sierra Nevada College. After graduating in 2016, I continued working with kids and as a personal assistant. Looking for new experiences, San Diego felt like the perfect place to be closer to the ocean and my family. I am new to the dental world but excited to be helping manage the front office.
In my free time, I love to be outdoors, traveling, laughing, and spending time with my big family! My goals in the office are to make sure each patient feels valued, comfortable, and receives quality service they deserve for a seamless dental experience.
Christy Lorson, RDH
I have been a practicing dental hygienist since 2006. After a short period of searching for the “right office” to work at, I discovered Dr. Koett and Dr. Olson’s practice and started working for them in 2007. I graduated with a Bachelors of Science degree in Dental Hygiene from the University of the Pacific School of Dentistry and recently completed an additional Alternative Practice licensure program. The aspect that I enjoy most about my career is the individual attention that the hygiene field allows me to have with my patients. Not only do I know the history of my patient’s teeth and oral hygiene concerns, but I also get the opportunity to know them personally as well. When I am not at the office I’m enjoying family time with my husband Chris and our two little girls Cayla & Camden.
Karolyn Kolker, RDH
I have been working in the dental profession as a hygienist for 38 years. I am also a certified Integrative Health coach and I bring that holistic approach to my dental hygiene practice. I feel it is important to look at each individual as unique, to help create a lifestyle that works best for their whole being. I feel so grateful and honored to be a part of this ethical and compassionate team.
Brooke Briglio, RDH
I obtained my Bachelor of Science degree in dental hygiene in 2009 from Fresno City College. I truly love my work in the dental field and I have a place in my heart for every patient that I treat. My greatest feelings of accomplishment come from helping build trust with patients that have had negative dental experiences in the past. I love helping them feel comfortable and build their trust along their dental journey.
I enjoy beach time with my husband and two beautiful daughters. My passions include the outdoors, gardening, reading, travelling and spending time with my loved ones.
Lena Yesulkova, RDA
I have worked in the dental field for 15 years. Through my studies in the field of dental health, I obtained my certification as a Registered Dental Assistant. I have been a part of Dr. Koett and Dr. Olson’s team since 2006. I enjoy working with my doctors and our patients because I know that our office is committed to providing quality care. I truly take pleasure in interacting with and caring for our patients. Outside of work I enjoy nature, gardening, cooking, traveling, reading and I love spending time with my husband, family and friends.
Katie Belaus, RDA
I am originally from Northern California and have lived here in North County for three years. Both of my siblings and parents have lived here for many, many years. I have been in the dental field for 20 years (unbelievable!!) and I definitely still enjoy it. I spend many weekends at Moonlight and Beacons beaches. With my free time, I love trying all the great cuisine San Diego has to offer. I also love ANY and ALL types of live music!
Alicia Sager, DA
I was born and raised here in San Diego. Why leave? The weather is amazing! I have been married for 14 years and I am a proud mom to a 9 year-old son. He plays baseball, so yes I’m a baseball mom! My husband and I opened a brewery in downtown Oceanside next to the pier. He takes a care of the brewery while I take care of teeth. I’ve been assisting in dentistry for over 15 years. I have been in all types of offices from general dentistry, to perio and ortho. I got my first taste of dentistry in a practice right here in Encinitas. That’s when I fell in love with it 15 years ago. My past time hobbies include traveling (anywhere tropical), snow boarding (powder with sunshine) and hanging with my family.
Christy Biber, RDA
I was born and raised in Vista and now reside in Oceanside. I love the southern California community! I have 3 children, Jacob (16), Kaden (13), and Aubire (7). I have been a dental assistant for 20 years and have a true passion for dentistry. My favorite part of being in the dental field is being able to provide a positive experience for people in an environment that most people don’t enjoy being in. I love caring for people and I treat my patients like family. I work with an excellent team of dental professionals that support my passion and that is very important to me. In my free time, I love the outdoors, kayaking, hiking, bowling, and spending time with my kids.

Our Fabulous Dental Team!
