Our Perio Team




Tarah Z

Office Manager

I joined Spokane periodontics in 2017.  I was thrilled to become apart of such a great office. I graduated dental assisting school in 2009 and have worked in the periodontal world of dentistry ever since, starting out as a surgical assistant and moving into the front office. I have a passion for patient education and helping people with a servants heart. At any given time at Spokane periodontics you may find me supporting the back clinic team or front office.

Outside of work You Will find me enjoying all the awesome outdoor activities the pacific northwest has to offer, chasing my two daughters around or spending quality time with my husband and family. 



Stephanie P 

Patient and Front Office Coordinator 

I entered the world of dentistry as a sterilization technician, became CPR certified and completed coursework from Obstructive Sleep Airway University. It wasn’t long before I moved my way to the front office specializing in all things insurance. My favorite part of being in the dental field is seeing patients grow confidence in having healthy smiles.

When I am not greeting and caring for our patients, I am out enjoying camping, fishing and spending time with my husband, two sons and two dogs. 


Merredith T

Insurance and Benefit Coordinator

Patient care has always  been my passion. I entered healthcare straight out of high school, spending 8 years as a nursing assistant before going into dentistry. I graduated from the Dental Assisting Program at Spokane Community College in 2011 and began my career in periodontics. Always a fan of further education, I returned to Spokane Community College for the Expanded Functions Dental Assisting program, graduating in 2015. After a brief time in general dentistry I realized that periodontics was where I belonged. I joined Dr. Johnson’s office in 2017 and am truly excited to come to work every day. I’m proud to be part of a team whose primary focus is quality patient care!

Jennifer S


I received a dental hygiene degree in 2003 from Clark college in Vancouver Washington. I moved to Spokane in 2003, started my career in periodontics and found an adoration for it. I married my husband in 2004 and had my son Gavin in 2005. I started working with Dr. Shellerud 2006 and also followed the practice transition over to Dr. Johnson. My love for dentistry started as a child with a great pediatric dentist as I had my own gamut of dental procedures throughout life. I am no stranger to dental surgeries. My goal is to build patient relationships, having them feel comfortable and confident in their provider and dental procedure options.

Hobbies, I love crossfit, outdoor activities, family time, lake days, gardening, cooking and wine tasting and eventually, one day traveling the world.

I graduated from Eastern Washington University with a bachelors of science in Dental Hygiene in 2010. Through the past 9 years I have been able to gain experience in many different dental settings, from corporate to holistic, but periodontal is by far my favorite, thus why I joined Spokane Periodontics in 2019. As a medical provider, I value being able to spend time with patients and helping them improve their periodontal and overall health. Making dental experiences more comfortable for patients is a daily goal of mine. I am a continuous learner and appreciate being able to pass the knowledge along to patients.

I married my high school sweetheart and we have two young children, a girl and a boy. Raising and teaching my children is a true joy. Summer is my favorite time of year, I love being outside enjoying the sunshine, playing in the water and taking advantage of the beautiful northwest. In what free time I have, you can find me tucked away reading a book.
