Welcome to Our Practice

Welcome to Catalina Dermatology, your Dermatologist in Tucson, AZ, Casa Grande, AZ, and Vail, AZ.

Choosing a physician or other medical provider can be a very difficult decision. It is essential to find someone who satisfies criteria you may have from a professional perspective, including the provider’s academic training and experience. However, it is equally important that the individual with whom you choose to treat makes you feel comfortable discussing your medical concerns.

Here at Catalina Dermatology, we pride ourselves on creating an environment that meets both these needs. Our physician and our physician assistants are not only exceptionally well-trained and experienced in the field of dermatology, but also intent on practicing medicine with empathy and compassion.

Catalina Dermatology has served Tucson, Arizona since 2004, and Casa Grande, Arizona since 2012. As of July 2022, Catalina Dermatology began seeing patients in a Vail satellite office, as well. In the spring of 2023, Troy Gustaveson, PA-C and Louise Greenwood, PA-C joined the practice. 

We welcome new patients to schedule an appointment and visit any of our three offices by calling 520-529-8883.
