Very poor customer service. They sent two of my bills to collections without any communication. I did not live at an address where I could receive Mail, so I missed their correspondence. I never once received an E-Mail, text, or phone call about my past due balance. I even had appointments there where I had to make payments, and they never once asked about my past due balance. This is over $20, so if they had simply asked I would have paid it. The staff is poorly trained and are not on top of their game.

I've been seen here in the past when I didn't have Kaiser and now I go in occasionally to buy some great products from them. I have never had any problems but I do miss Cindy at the front desk.

Wonder why such a bad rap. I have gone to see Erin for years. The new lady at the desk--while not the most tech savvy--is sweet and a great addition. Someone messed up our appointments but they sorted it out. In past years...they have not billed me and then when I come in say, "you owe money" and I'm shocked-huh? However, at the end of the day I'm there for a look see by a good practitioner-- and that's what Erin is.

Went there for a peeling plaque that was on my face., and skin examination They did a scraping and sent it off, but in two visits I NEVER SAW A DOCTOR. I did request to see one, but said they were unavailable. They kept me waiting 45 minutes, and a nurse saw me for about 5 minutes. There
were 5 people sitting around the office shooting the breeze. Never did
have a diagnosis. WONT BE GOING Back.

Great doctors, but the front desk lady is very rude and unprofessional. I haven't been back for many years and I always remember how nice the front desk girls were. I would feel very uncomfortable going back after rude treatment.

I have had a two skin cancer surgeries at North Bay Dermatology at Lynch Creek this year. The most recent required creating two pencil eraser sized holes in the side of my nose. Dr. Centurion removed a small amount of tissue at a time, followed by biopsies done right in the office. He removed tissue until the biopsies came back 100% clean, all in about 3 hours.

Between surgeries, patients wait in the office kitchen stocked with a fresh coffee maker and a spread with fresh bagels and pastries. The 3rd biopsy was cancer free and I was able to go home as I live close by.

A few hours later

Horrible place. The tattood lady in the front is the rudest person. Absolutely no customer service. I tried to get my biopsy test results and got no call back for 5 weeks. When I finally got through to the lady in the front she acted like I was lying to her. Never come here.

I have been going to this office for several years now and have usually had to wait for my appointment 10-15 mins. I went last Mon for a 9:15 appointment and arrived at 9:10. I was very soon taken to an examination room where I undressed. After 25 mins, it was now 9:40, having seen nobody since being shown to the examination room I dressed and left. Extremely unprofessional behavior. I did have to return two days later for an unrelated matter and asked to speak to the office manager. They do not have one. I then asked the receptionist who I registered a complaint with. She asked me what the problem

There is no negotiating, there is no heart, there is no effort to hear my need. With an appointment a whole week away, I called saying I am desperate with what might be hives all over my body or scabies or an allergy to one of my meds. All I know is I need only a few minutes for the doc to look and prescribe something! I am in a great deal of discomfort and was told to go to the emergency room if it is that bad. I asked could I get on a cancellation list? Is there any way I could be squeezed in for 10 minutes? I am not a new patient.

With attitude lacking compassion I was told that there

I feel very fortunate to have found this office after moving to Petaluma. Everyone was very polite and caring and treated me as a friend. There was a mix-up with my insurance and they were very patient and helped get it resolved without asking for a payment from me.
Unfortunately we moved out of state and I have lost one of the best dermatologists I ever had and miss my friends in the office.

This is the worst dermatologist ever! They lie right to your face do unnecessary procedures so they can hike up your bill and charge you an arm and a leg, I was having a little bit of skin cancer mark removed from my arm and all of the sudden they are scrapping my nose which had nothing wrong with it she said looks like there might be something there WELL nothing was there! My point to this is I asked, you are taking a chunk off the top of my nose will this heal and I won't see a hole in my nose...she guaranteed me it would heal and I wouldn't even notice I asked for the Dr. and even

Came here to do a full body exam.
My wait was minimal, just a little bit longer than me finishing my paperwork.
My main concern was skin cancer [I used to spend A LOT of time in the sun (was a competitive swimmer for many years), had a bad habit of not using sunscreen, have a lot of moles, and have been getting sunburn at lot more than I used to].
During the exam they asked me if I was concerned about my flakes and the eczema (some variation of it) that I have.
Everything was electronic (done on an ipad) and my perceptions were ready within a couple hours of me leaving.
I received my bill

I met with Tracy for a cosmetic dermatology consult. Was seen back very close to my original appointment time. Tracy was extremely warm and welcoming. After doing a photo analysis of my skin and asking me very thorough questions about my skin care regimen, she took a lot of time explaining to me the different options available to me to address my main concerns. I felt like she really listened and was truly interested in helping me have the healthiest skin possible for a woman my age. I decided to start a series of peels. Tracy took her time with the procedure and also included treatment of my

New patient, went in for a full body scan to make note of any moles and skin tags. Was seen by a nurse, not a doctor. She performed a biopsy right then and there. Seemed very capable.

I was more than slightly pissed when I went to pick up my RX's for dry skin, dry scalp, etc. (4 RX in total) and the cost after insurance to me was over $900. What the hell? There is NO WAY I can pay that for one month, but especially not as a bi monthly refill. Who the hell can afford that? It took me 3 phone calls and 2 days without any meds for the nurse and the pharmacy to straighten it out and magically

The doctors are good, quick visits and we felt very rushed each time we went in. But after treatment is complete for this current issue I will look for another office. The girls at the desk are rude and impatient on the phone and in person. They tisk and sigh and act imposed upon, often they don't acknowledge you when you enter the room, and also get upset that we didn't go for lab work prior to appointment! We were never told to go for this lab work!

I went to see Dr. Centurion last year to have two moles removed. The first question I asked was 'will my insurance cover this'. He said they would look into it, and came back when schedule the return visit to remove them, telling 'We talked to your insurance and they're going to cover it.

A couple of months after the procedure, I started getting payment notices from North Bay Dermatology saying that my insurance was not responding. Upon further investigation my insurance made it clear that they did NOT cover this, and weren't going to pay. So I have no doubt that the office

Knowing nothing about her and having no prior experience with a dermatologist, I went to see Calamia Rae for adult asian acne. She gave me an antibiotic and 2 different kinds of tubes to apply morning and night. Retin-A was one of the tubes. My acne cleared up - the first time in my whole life!!!! What a miracle. I have battled it all my life. Only problem... is it has since come back. Not as bad as before but.... so she told me the body becomes immune to the antibiotics and I might have to take birth control pills. I have no reason to take birth control pills normally... and I've heard bad
