Meet Our Team of Expert Billers!

Michael Evans

Co-Owner & Billing Specialist

I entered the medical billing field in 2007. I have since honed a passion and skill for analyzing and breaking down problems, which results in effective and efficient solutions. I truly value keeping all our services local. This enables us to provide a much more personalized and complete service. I also believe this approach strongly supports our local communities, and of course the great team of employees that work here at Integrity. Every provider/client, whether small or large, will receive caring, transparent, diligent, and detail-oriented work from their dedicated biller or billing team. My intent is to take care of our provider’s billing needs up until they retire. I am so confident that you will love and appreciate our work and service, that we will not even ask you to sign a contract. Integrity, Honesty, and Transparency are our motto!

Rita Bustamante

Co-Owner & Billing Specialist
I started “Integrity Medical Billing” on my kitchen table in 2004 after working as a medical biller for my brother and then for a large billing service here in Tucson. Early on it was always my wish to serve the smaller practices in our community with the focus they deserve. I have been so blessed to have now served the providers of this community and beyond for almost 23 years. I graduated from the “American Academy of Professional Coders” with my certification in 2001. It would be my pleasure to continue on as a medical biller until I retire. Working hard and with much respect and humility to help my providers with all of their insurance reimbursement wants and needs.

Rachel Medeiros-Vega

Office Manager & Billing Supervisor
I have been in the Medical Billing and Coding field for over 15 years. I started billing, by chance, for a hospital in Tucson AZ when I was just a teenager and fell in love with my job! I’ve since earned my HITech-AAS & continue to learn and embrace the ever-changing landscape that is medical billing. I enjoy problem solving and helping providers and patients be at ease when it comes to billing, so their care and treatment can remain everyone’s main focus!


Billing Team Lead
I have been working in the health care industry for approximately 7 years. I started taking calls for an insurance company and have worked my way up to work on the other end of the line working for Integrity Medical Billing and enjoy all the many things I have learned. I am currently continuing my education to be a credentialing specialist and can’t wait to learn what’s next.

I’ve been doing Billing and Coding for this company for over 3 years now. I came into the billing field not knowing what to expect but ended up finding a career I truly enjoy. I love working with patients and solving problems. I can’t wait to keep working for Integrity Medical Billing and hope to grow with the company and expand my education further in the future as well.
