Meet the Staff


Shirley Jacobsen

I have always said I’ll know what I want to be when I grow up. Well, I’m past grown up and I never found that one thing, and I am glad, as I have enjoyed all the endeavors I’ve found myself in. I’ve been a flight attendant, had my own massage therapy business, and been in the dental arena primarily in Periodontics and Endodontics. I joined Northgate Endodontics in 2006. In my free time, I enjoy nature walks, reading, and visiting with great friends.

Sarah Khorrami

I received my Dental Assistant certification in 2006 and joined Northgate Endodontics in November 2007. I wanted to work in the dental field since I was a child. I enjoy working with patients and making their visits as comfortable as possible.

Outside of work, I am a photographer specializing in newborn photography. I love camping in Eastern Washington and spending time with my family, including my two young children.


Beth Highfill

I am originally for Northern California. I Moved to Washington state in 2005, and began working as a dental assistant in 2006. My area of interest in dentistry is Endodontics. I joined the team at Northgate endodontics in March 2017 to pursue my interest. I love to be a part of the team taking care of our patients'needs from the beginning to the end of the treatment. My hope is to help make each patient's's dental procedure a pleasant and comfortable experience.

On Weekends when I am not working, I enjoy gardening, hiking and camping around the PNW. I am passionate about volunteering at the Greenwood senior center and Phinney Ridge neighborhood association. Furthermore, I enjoy spending quality time with my friends and family.


Adriana Ortiz-Cruz

I started working at Northgate Endodontics in 2016. I was ready to change my career path after running the bilingual center at Green Lake for 3 years. I am a type of person who likes to be challenged and my career path has taken me to work in the field of dentistry. I have enjoyed the time that I have spent here at Northgate Endodontics. I have been able to interact with our patients and learn a little bit of each and one of them. I can say that I love the job that I do because I learn something new everyday. I truly enjoy having the direct interaction with patients and I take it upon myself to make the patient's experience here as pleasant as possible.

I was born in Oaxaca, Mexico. My family and I moved to Seattle at the age of seven and I have resided here ever since. I graduated from Tyee High School in 2008. I moved to Bellingham the following year and attended Western Washington University. I am the first in my family to graduate from a university. My mother has been my inspiration to continue with my education. I hope one day to return to school and receive my Masters in Education and Leadership. It is a passion of mine to help others in need and I love interacting with people.

In my free time, I enjoy spending time with my family. I adore my two nieces Chloe and Zoey. I love dancing, hiking, cooking and baking. I enjoy playing Volleyball and Fastpitch. I enjoy watching football and soccer. I always like having fun and living life to the fullest.


Michelle Leadbetter

I joined Northgate Endodontics as part-time office manager in 2015, and I’m thrilled to work with such a great team. I find fulfillment in my duties in the office as I love helping others in small ways. I enjoy reassuring patients who have dental fears, and I am keen on helping people understand their dental insurance coverage so they can avoid surprises. Meeting new patients is something I look forward to each day.

In my free time I like to explore Seattle with my husband, make crafts of all kinds, and volunteer at a local soup kitchen. I’m excited to welcome my first child in June 2017..
