Meet The Team


Office Manager


Lori is our office manager and is passionate about supporting our patients and staff. With over 20 years of experience in the dental field she professes it is our outstanding clinical care and our ethical way of doing business that makes her never want to leave. When she’s not in the office she enjoys the heck out of her three kids, will occasionally commute on her Yamaha V-Star and has a unique appreciation for Oregon’s liquid sunshine. “This isn’t a job. It’s a place to come and do great things with amazing people”.


Patient Coordinator


Sydney is the first person you speak to on the phone or see when walking through our door! Originally from the Bay Area, Sydney enjoys reading, spending time with her family, exploring all the unique spots Portland has to offer, as well as adventuring with her way too adorable silver lab puppy, Hazel!  Sydney is constantly inspired by the doctors here in our office, and plans to expand on her career in dentistry by applying to dental school in the next couple of years. She loves getting to know each and every patient here in the office, and thoroughly enjoys seeing them successfully reclaim their confidence in their smiles again.

Rachel for Web



Rachel joined our front office team in September 2020. She is a native Oregonian and was raised in Canby, Oregon. She has a deep love for cooking, live music, and enjoying time with her boyfriend of nine years along with their three rescue cats Drogo, Khaleesi, and Laszlo. She came to our office with a 15 year background in Early Childhood Education. Rachel was seeking a new adventure and saw our office as the perfect place grow. She is in awe and inspired by every member of our team and is ready to learn. She is excited to pursue her passion of connecting, listening, and helping others in her community.

Jill for Web

Dental Assistant


We are delighted to welcome Jill to our team! She brings with her 15 years of experience in dental specialties. Assisting our doctors in offering the best care and patient experience is her top priority. She sets high standards and thrives on exceeding expectations. Jill is a life-long Pacific Northwest native and loves exploring the great outdoors with her husband and daughter. Abundant creativity fuels her passion for photography. This is an entirely self-taught skill which she has demonstrated exceptional skill in.


Dental Assistant


Chelsea has been a dental assistant since 2015. She joined Advanced Dentistry because she loves the great relationships she gets to build with our patients and watching their smiles transform from the first appointment to the last. She learns something new every day working with Dr. Halmos and Dr. Manning. She was born and raised in Lebanon, Oregon and moved to Portland in 2013. In her free time she enjoys spending time outdoors (when it’s not raining), playing with her cats (Walter and Stella), cooking and traveling to new places.

Megan for Web

Megan has enjoyed being a dental assistant since graduating from CHCI in Exton, Pennsylvania in 2016.  She especially values the engaging combination of compassion, creativity & critical thinking that working in prosthodontics provides. Megan moved to Portland from Pennsylvania in 2017 and has since acquired two wonderful canine companions who keep her constantly busy exploring the great PNW. (Potatoe & Bean)
