California Dermatology Care

Quick appointment and friendly staff. All in all it was a smooth and enjoyable experience.

Fantastic experience with Mary Katz. She calmed my daughter’s nerves and created a plan that would be easy for her to follow.

I've been to some of the most renowned dermatologists all over the US - for 25+ years - for treatment of rosacea + seb derm. Some were excellent, some were ok, and some were uninformed, disappointing, and borderline negligent. All of them were very expensive. After seeing the great crew at this office, especially Mary Katz PA, this veteran of the dermatology trenches grants 5 stars for knowledge, skill, bedside manner, and value. I would even add a bonus star if there was one available.

I’m so glad my last dermatologist retired or I never would have found Cal Derm.
My favorite health care providers have all been PAs, and Mary is at the top of the list.
She’s always attentive and my appointments never feel rushed.
The entire staff, both in Livermore and San Ramon, makes me feel comfortable and well cared for.

Such a welcoming and comfortable office. Doctor is patient and listens and looks over all your concerns. Explains the follow up and any medication.

Everyone was so friendly and welcoming. Mary Katz was so thorough, professional, friendly, and really listened to my needs and made it work. Highly recommend.

Loved Annie, but Mary is just as awesome. The environment is so comfortable. Easy to discuss issues/concerns.

Absolutely wonderful first visit! The staff were friendly, respectful, and attentive. Stella was easy to talk to and caring. The appointment was a breeze.

They listened, and were very responsive. My teenager and I really liked Dr Leon. Good bedside manner, listened, and explained all.

Stella was absolutely amazing! She was patient with all of her explanations and put a first timer at ease.

The staff, including the receptionist and the MA, was friendly and attentive. Dr Leon took the time to listen to my background and concerns regarding my skin condition. She did a full body scan. She then discussed in detail my skin issues and treatment options and answered all my questions. She was very patient, caring, and well informed.

This was a very good experience! I highly recommend this clinic!

Loved meeting Mary. She was very thorough and I felt very comfortable with her. The staff was very pleasant, however it sounded like they were having a party, got a little loud at one point

This was my first visit. Very impressed with the staff and offices. Stella answered all my questions and had a great “bed side” manner. Highly recommend.

Went in to have a few moles checked out and one removed. The staff was super nice and friendly, they made me feel very comfortable. Stella did a great job. It was a super quick and easy process.

I’ve been dealing with melasma for awhile now. It’s a tricky diagnosis to handle and they definitely know what they’re talking about!

These people were so friendly and helpful! PA Mary Katz especially was super informative and obviously cared very much. 100% recommended
