That's a bigger deal than it sounds. I have a really low pain tolerance and facials can absolutely hurt, plus I'm a sensitive person in general, so feeling relaxed beforesomeone starts working on my face matters to me probably more than it should. She never made me feel weird about any of it and checked in the whole way through. she also really knows skin. The results lasted way longer than I expected, and she doesn't disappear once the appointment is over. Her recommendations and support outside the chair are why I finally have a home routine that actually works. Overall awesome experience, I'll definitely be back!

I must say, Dr. Zand was simply outstanding. She carefully examined my concerns and she patiently discussed various treatment options with me. What was particularly impressive was the care, patience, and compassion the doctor exhibited throughout. It is so rare to find a physician who is knowledgeable and yet is also so concerned about informing the patient and empowering the patient to make the decision that best meets their goals. Particularly in the area of cosmetic procedures, Dr. Zand is a truly exceptional resource.

Dr. Denkler is the only doctor I've been to that performs the needle Aponeurotomy and it works. His expertise is amazing and my three fingers are now straight. I have been to many other doctors for Xiaflex and had surgeries. This procedure by Dr. Denkler gives the best result. I am grateful that I found him and can't thank him enough for helping me. Also, I saw him in 2009. He performed the needle aponeurotomy on my little finger and it is still Straight!

I developed some blood clots and substantial pain in my arm. Without me feeling a thing, he opened it up and repaired it all. This past few weeks, I had a swollen lymph node beneath my ear drained in a local hospital - a simple procedure - and apparently the doctor punctured a vein and it swelled to three times the size it was when I came in. For two weeks I was in agony as it continued to swell while the hospital staff said "nothing we can do. It will heal eventually." This after CT scans, MRI's, everything. The swelling pressed on my ear canal, my jaw, and I looked like Quasimodo. I went to Keith Denkler in excruciating pain. In 30 minutes he drained 13 cc's of dark blood and relieved the pain - I hardly felt anything as he did it. The next day he drained another 13 cc's - and over the weekend, the massive swelling in my jaw continued to shring to 1/4 of the original side. He did it all with little or no discomfort. I've been able to work, sleep and avoid pain meds - none of which was true for over two agonizing weeks. This is a doctor who cares who knows, and should be teaching the others how to do this work. Common sense is genius in blue jeans. Keith Denkler has it all.

    I had such a lovely top notch experience at PSS Marin County…read more Heather and Kelly were warm, down-to-earth, and actually listened to what I wanted...definitely not just another appointment on the calendar. I have to say too the whole team as well was beyond welcoming and inviting. Which for me is HUGE and helps put me at ease and my insecurities are out the window. All questions and concerns are answered!! The location is clutch too right off Sir Francis Drake..beautiful and calming, which made the whole visit easy and chill. I love the results and left feeling confident in their expertise and 100 percent truly cared for. I've already told my girlfriends to check them out and will keep sending people their way. If you want skilled, honest trustworthy plastic surgery specialists in Marin County with a personal touch, go see them. ALL the way CLASS acts!

    UPDATE and response to Lvvia and Owner...No stars.. The Clinics response below is untrue. They…read moreNEVER reached out. I called them, I was in their "clinic" 4 separate times - they visually say this wound. Their response was non- emergent. I am now day 3 in hospital. Day 3 of continuous antibiotics- due to this unsafe - in surgery practices. Lift and 100 cc does not look like this and now with the fluid gone they are sagging and implants infected. They will be removed in a few hours and I will have to start again with my desired lift in a year after reconstruction and recovery. Again no apology's, no email, no calls. I called the clinic Friday. She asked me to return I told her it was a VERY UNSAFE PLACE at least for me. No I will never return, no more referrals, no more positive energy. Warmly, Anna Stevens

Have been to this office several times to enjoy their Signature (and Deluxe) Hydrafacials. The process feels great and my skin looks great afterwards. The offices are so bright and clean, it's a very relaxing atmosphere. Aesthetician Mae (and previous aesthetician Patricia) are very good at what they do including making suggestions/recommendations about your skincare. Highly recommend coming here for hydrafacials and other skincare needs.

    My family of four has been going to Southern Marin Dermatology for years, and we have generally had…read morevery good experiences with the doctors and nurses. Unfortunately, our experiences with the front desk have been consistently frustrating and seem to be getting worse. The most concerning experience occurred when my husband was diagnosed with melanoma. After receiving such a frightening diagnosis, we waited and waited for an appointment and for information about what would happen next. We were frustrated by the lack of communication and ultimately contacted UCSF, where we were able to get an appointment quickly and received a clear explanation of the diagnosis and next steps. We've had other frustrating administrative experiences as well. I handle the medical scheduling for our family because my husband has a demanding work schedule. When I called to make an appointment for him, I was told that he needed to sign a HIPAA authorization form. I asked if they could email the form so he could sign it, but I was told he had to come into the office in person just to sign it. This seemed unnecessarily difficult. More recently, before making appointments, the front desk required us to pay outstanding balances immediately--including one bill we had not even received yet. We use an HSA to pay our medical expenses, so being required to make an unexpected payment on the spot was particularly frustrating. We have stayed with Southern Marin Dermatology because we appreciate the doctors and nurses and believe they provide good medical care. But dealing with the front desk has become increasingly difficult. I hope the practice takes these concerns seriously and improves its communication, billing practices, and overall administrative experience. Good medical care deserves an equally professional and compassionate front-office experience.
