Gretchen Marcoulier, RDH
Registered Dental Hygienist

Hello! I graduated with my dental hygiene degree in 2007 from my home town of Reno/Tahoe, Nevada. I practiced there for the first half of my career before relocating to Oregon. I love all aspects of my job and truly enjoy connecting with each and every individual and keeping up with where life takes them through the years. I’m honored to be part of a team who takes pride in providing great care to help you live your best life!

In my spare time, my husband and I enjoy hiking, camping and traveling with our little girl. We also love to catch a Winterhawks or Hops game. I genuinely enjoy being around people and love to make new friendships every chance I get.


I was born and raised in Northern California where I trained as a dental assistant and developed a passion for the dental field.  I returned to school and graduated with my BS in Dental Hygiene Studies from Pacific University.  I enjoy all aspects of the dental field and love helping people improve their oral health. I am excited to be part of a team that focuses on providing exceptional dentistry.

In my spare time, I enjoy exploring the Pacific Northwest and participating in outdoor activities with my husband, children and our dog.

Elly Bautista

Dental Assistant


I was born in El Salvador and arrived in the United States in 2009.  One of my dreams was always to work in the medical field.  I joined the 360 Dentistry Team as a sterilization technician in 2021 and have advanced to become a chairside dental assistant.  I love helping others and I am very lucky to be in this office.  Everyone is very friendly and cares about others.

In my free time I love to go camping, fishing and enjoy nature with my daughter, husband and other family.

Hallie Malcom

Dental Assistant

Hello!  I am a native Oregonian and have been in the dental field for many years.  I earned my dental assisting certificate from Portland Community College.  Most of my experience has been in general dentistry.  Prior to joining the 360 Dentistry team I had the opportunity to expand my skills in pediatric dentistry - assisting on pediatric patients during full mouth rehabilitation cases under general anesthesia.  What I enjoy most about my career is interacting with patients, getting to know them, and helping my dentists provide quality dental care.

I like to spend my free time with my husband, three daughters, our family and friends.  I feel especially blessed to be surrounded by my large extended family who I enjoy celebrating holidays, milestones, and summer campouts.  My hobbies include my pets, gardening, boating, beach trips, camping, and hiking. 


I look forward to caring for your oral health and helping you have a positive dental experience.
