Meet Dr. Catalina
Dr. Giselle Catalina is a licensed Naturopathic Medical Doctor who graduated from Bastyr University in San Diego. Originally from Maine, she holds a B.A. from Georgetown University and she is fluent in Spanish.
She treats a wide variety of conditions, with an emphasis on digestive, autoimmune, hormonal, and cardiometabolic concerns. She looks at all aspects of a person's mental, emotional, and physical health, along with environment, genetics, and lifestyle, to create a personalized and dynamic treatment plan.
She applies her extensive training in functional medicine and advanced labs to identify the pathways that are not working, treat root causes of symptoms, and pave the road to optimal health.

The right therapy for you
Whether you've tried everything or don't even know where to begin, we will collaborate on treatment goals and a realistic roadmap for how to get there.
As a Naturopathic Doctor, I use a wide range of modalities. I don't use one-size-fits-all protocols; I tailor the plan to you. Many naturopathic treatments offer multiple benefits at once, unlike prescription drugs used for a single action.
If it doesn't work as well as expected, or life gets in the way of sticking to the plan, we will try something else. You always have a voice — and a choice — when it comes to treatment.
