Dr. Samuel Koo’s Staff
Meet the team
Claudia Kalotay, PAC
I have been with Dr. Koo since 2012. I am originally from Mercer Island, Washington and graduated from the University of Washington MEDEX PA Program. I play an important role in the practice of assisting in surgery, providing patient education, and maintaining post-operative care. As a PA I have the ability to diagnose and treat medical and surgical problems. I can prescribe medication, give injections, and assist Dr. Koo in surgery. I spend significant time with patients ensuring that their needs are met with full attention to detail. I am heartedly invested in every patient’s outcome. Outside of work I enjoy family time especially with my nieces and nephews. I am always looking for new adventures in the northwest including hiking, running, and tennis.
Gema G. Mancilla, CMA
I have been a Certified Medical Assistant since 2013. I initially started in pediatrics at Children’s Hospital but after 3 years I decided that I was ready learn more and put more of my skill sets to use. Since starting with Dr. Koo and his practice I’ve thoroughly enjoyed developing relationships with our patients and seeing how pleased they are with their care. In my free time I like to watch movies, explore new places outdoors, and spend time with friends and family.
