To Whom It May Concern;
I am writing this letter of reference for Christina Williams, respiratory therapist. I have worked with her
at the California Medical Facility in Vacaville, Ca since December, 2010. This medical facility treats prison
inmates. The patients can be difficult at times. Christina has always been helpful, professional with the
inmates and staff. She demonstrates a good field of knowledge in her area of expertise. I can always
count on her. I would highly recommend her.
Please feel free to contact me if you have any questions.
Sincerely,
Roxanne Sanders, MD
