LTCDR (SW) Kirk Shim

President / Awards Coordinator

Hello, I’ve been stationed at Tuba City Hospital since 2011 and I have had the opportunity to serve the Navajo Nation and my country at the same time. It is my hope and desire that others seeking the chance to do good to consider this region as a choice of assignments. The people are welcoming and will appreciate your efforts. The work that you will do will be important, satisfying and much needed. Looking forward to meeting you all.


LTCDR Twyla Sharp

Vice President

My name is Twyla Sharp. I was born and raised in Salt Lake City, Utah. I lived there until six years ago when I graduated college, moved to Northern Arizona, and joined the TCRHCC team. I started working here on the adult care unit (ACU) as a new graduate, advancing to a lead clinical nurse after two years and joining the PHS at roughly the same time. Two years later I helped out during a transitional period and served as interim ASCN on the floor. At the end of 2014 I made an exciting change and joined the quality division as a utilization review (UR) nurse. Joining the TCRHCC team has become one of the most important moves of my life; it has transformed me in ways I could have never imagined. I look forward to many more years here, serving in this new role as the Grand Canyon COA vice president.

CDR Veronica Granger


I have been a nurse for 13 years at TCRHCC. I am Navajo, born and raised in Tuba City, Arizona. I am of the Red Bottom Clan and Manygoat Clan. My husbandís name is Marlin Granger and he is also employed at TCRHCC in the SPD Dept. We have 3 children and one sweet grandbaby. I went through grade school in the Tuba City Unified School District and got my BSN at Northern Arizona University.

I moved back to Tuba City because I saw the need for nurses in my community. I started as a Med/Surg nurse on ACU for 3 years, 5 years in SSS/PACU and 3 years as Lead Nurse in the Internal Medicine Clinic.

I enjoy living in Tuba City because all my family is here. I enjoy cooking, baking, reading and spending time with family and friends.
