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”.




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.

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.
