About Karissa Valles and Banner Safety Practices

Care Philosophy

All foods can be nourishing to the body and can fit into a healthy diet; prevention is the best medicine, so it is important to fuel your body with nutrient rich foods that fit your individual needs and health goals.

Interests & Activities

I love spending time with family and friends, exploring fun activities around the downtown Phoenix area. My favorite is trying a variety of foods from various cultures and visiting new spots around town. I also enjoy traveling, reading a good book, and relaxing at home.

All Banner facilities are pleased to provide interpretation services to our patients and their companions for no charge - just ask when you arrive.
