Susan Mishima

Practice Manager

Hello, I am a native Portlander and I have been a dental office administrator for over 25 years.  I enjoy dentistry because each day there is something new to learn and it is gratifying to see dentistry transform people’s lives.  I am excited to be the newest member of the 360 Dentistry team.  Dr Crocker and her staff are dedicated to ensuring that every patient receives the highest standard of care possible, and I look forward to being a part of this great team.


My husband and I have 3 adult children and 2 sweet Labrador retrievers. In my spare time you will find me exploring new Portland restaurants with the kids, hiking in the gorge or at the beach feet in the sand.  I love knitting, yoga and cycling with my hubby. I look forward to meeting you.


Lucy Wade

Patient Coordinator

Hello! I moved to Portland, OR in June 2021 from West Michigan.  I grew up in the dental field as my Grandpa and Uncle are both dentists. I started my dental career in Michigan as a dental assistant.  I enjoyed being an assistant, but am now pursuing a degree in business management and am transitioning my skills to the front office. I am very excited to learn about the business side of Dentistry and be of service to patients! I’m honored and excited to be apart of the 360 Dentistry team and look forward to providing a positive experience!

I spend my free time hiking, golfing and skiing! I’ve loved the PNW so far and can’t wait to explore my new home!

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.


Kristina Sinclair, RDH

Registered Dental Hygienist

I am a native Oregonian and grew up on the outskirts of North Plains. Prior to becoming a dental hygienist, I worked as a dental assistant and started out my career at 360 Dentistry in 2010! After graduating from Pacific University in 2016 with a bachelors in Dental Science, I worked for a non profit clinic serving migrant workers and low income families. I am so happy to be back at 360 Dentistry again!
I love all aspects of dentistry but I mostly love that I get to make a difference in my patients' oral health and create long lasting relationships.

In my spare time, I love spending time with my husband, 2 daughters and 2 dogs. We love to camp, explore the PNW, travel and eat at great restaurants!

Cassy Ford

Dental Assistant

I grew up on the Oregon Coast then moved to Portland in early 2013 where I finished my dental program and became a Dental Assistant. I have worked closely with the team of 360 Dentistry for the past 9 years but as of 2019 I joined the team full time and I could not be happier. I love all aspects of the dental field but truly love gaining those relationships with our patients and enjoy being a part of providing the best care for our patients. I am very fortunate to be a part of the 360 Dentistry team.


In my spare time I enjoy exploring the PNW with my two dogs Franklin and Noelle along with cheering on the Trail Blazers along with the Oregon Ducks. I also enjoy camping and traveling as much as I can along with some slight retail therapy when needed. 


Holly Thompson

Dental Assistant

I grew up in Maryland and worked as a dental assistant for a year before getting married and moving to the Portland area in 2014.  I’m very thankful to have found such an amazing dental team in which to learn and grow these last 8 years.  I have loved getting to know our patients throughout the years and I’m happy to have the opportunity to return part time after having my daughter.  I’m honored to work alongside doctors and team members who focus on positive patient experiences and the highest quality of dentistry.

I love to spend time with my husband and one year old daughter, Abby.  We love to cook yummy foods at home, get outside to enjoy the sunshine on walks and hikes, camping, and building community in our hometown Newberg
