Jessica Martyniuk

Provider Relations Specialist – Northern Nevada

Hospitals, Hospitalists, ASCs, SNFs/LTAC, Urgent Care Facilities, Medical Transport, Air Ambulance, All Specialties, Rural


I have been in the healthcare industry for almost 14 years. Working my way up from Customer Advocate in a call center, to Operations/Process Expert, to Process Improvement and Product Ownership for the Anthem Federal Employee Program. What I enjoyed the most over the years was being able to work one on one with Members and Providers, and helping to make their experience with the company, a positive and beneficial one. What brought me to Centene is an appreciation for their format and company values where I can continue to work directly with Providers and play a key role in the company's success, but with a more personable approach. I'm excited to be here, and for the opportunity to serve and grow with my community.

I entered the medical industry to explore my passion for helping those in need and making a difference in their lives. In addition to my primary job functions, I am driven, dedicated, and committed to the diversity that healthcare brings especially in terms of working with different specialties and people from different backgrounds that come together to benefit both patients as well as providers. I currently live in Reno, Nevada where I was both born and raised. My beautiful children are my world. When I am not engaged in their activities, I love to enjoy my city and attend community events. I also love spending time with friends and loved ones. My personal and professional goals align by leading me towards a brighter future, not only for my family and myself, but also for the betterment of my community and those closest to me. My hope in life is to create a positive impact on others, my organization, and society at large.

Christina Galan

Provider Engagement Program Manager – Northern Nevada

VBC, P4P, CoC, Quality


I started working in healthcare after graduating from Oregon State University over 15 years ago. My first job was in customer service where I gained valuable experience and knowledge about being quick on my feet. From there, I wanted to purse working directly with providers along with learning more about contracting. I decided to focus on provider relations. My service philosophy is to always be responsive. I may not always know the answer, but I believe in responding to each of my providers in a timely manner. I will always work on your behalf. I am a wife and a mom to two daughters.  We love living in Northern Nevada because we get to hike, ski and enjoy beautiful Lake Tahoe.

I enjoy spending time with my family and friends, traveling, shopping and live music.

I graduated from the University of Nevada Las Vegas in 2018 with a bachelor’s degree in Healthcare Administration. Since then, I’ve worked in several roles – beginning my journey in utilization management, then hospital operations, and now provider relations. Working in the industry has taught me to appreciate the accessibility and delivery of quality healthcare. This growing appreciation continually inspires me to expand my knowledge and develop my skills in this space. In turn, I hope that this will aid me in giving back to my community by leaving a lasting impact. I believe more than anything that we should all advocate for each other. By working in healthcare, I know I can do just that.
