Diana Parnell, MD has been our dermatologist for many years. There is no doubt she added many years to my husband's life when she discovered melanoma issues that required several surgeries. Both of us get regular check ups. The office staff, nurses are excellent.

I have been going to the California Skin Institute offices of Greg S Morganroth MD for more than 10 years to get dermatology care. The Kentfield office is my third, after first going to the office in Mountain View and then San Jose. I have received exceptional care and service at all of them. My most recent appointment April 10, 2025 (and Nov 2024 before that) was at the Kentfield office with Jennifer Hayes, MD, and the doctor and the office staff (like Lissette) were both knowledgeable, friendly, and accommodating (in that I was allowed to bring my small, female, 15-lb Maltipoo). The doctor relieved my worries about a brown spot on my back I hadn't seen before. Dr Hayes is also a animal lover and I had fun at the office visit. I recommend to all my friends and family, who are all senior citizens now, to get regular checkups, and I tell them about the great care I've gotten at the California Skin Institute.

Alice Chen
So Thankful for the care of Dr. Parnell and the warmth of her office staff! Dr. Parnell and her years of experience and professionalism has helped me with many issues throughout the years—including a second degree burn to the face that could have scarred me for life. Thankfully, with Dr. Parnell’s knowledge and skills, I no longer have any scars on my face. I believe this could not have been achieved by other doctors and would recommend Dr. Parnell to anyone!
Lisa Sirabella
I was thrilled with the results!!! I plan to recommend them to all my family and friends. Don’t walk, RUN to this establishment! You can trust them with any skin procedure, advice, recommendations, etc. I will be a regular from today forward!

yelena pesic
This place rocks! I’ve been going here for years. While I enjoy my facials, micro needling gives my skin long lasting benefits that keeps it firmer, smoother, and glowing! Also, they always find a way to squeeze me in for skin emergencies. Ask for Noelle, she’s the best!

Dr. Parnell and her entire team is awesome. They're extremely knowledgeable and provide exceptional customer service. Highly recommend 10/10.
Cate Eranthe
Happy to see Dr. Parnell again! She is the best. This new business does have some different processes and I was a bit concerned that biopsies now take 2 or 3 weeks to come back. Under her old practice it was no more than 10 days.

Dr. Lowenstein rules. I’ve seen a few derms and he’s by far the most thorough. I don’t like seeing male docs but he’s the exception.

Michael Romanko
Dr Loeinstein is amazing and very quick. Makes you feel cared for and taken care of not just during the appointment but anytime in between and very easy efficient scheduling. Amazing staff! Could not recommend more!
Stephanie Kerry
I love Dr. Lowenstein. He's full of knowledge and doesn't try to upsell anything. He got the work done and kept it gentle. His assistant, Adriana, is WONDERFUL. He's found a gem with her. She's patient, kind, smart and friendly. Everyone was helpful. I left with exactly what I came in for and more. I wish they weren't so rushed. I think they overbook. Probably because they're in demand.
Ashleigh Emerick
Great staff. Punctual. Considerate. Dr was friendly and thorough. Highly recommend.
Donna Barker
Everyone in the office was efficient and friendly. I liked Dr. Lowenstein also for his tlc.

Best people and best Dermatologist I've ever had in the States. They went the extra mile to make my visit a comfortable one and they all had a great sense of humor. I went out of the Kaiser system to avoid delays in getting a skin biopsy. So glad I did. Thank you CSI!

Samantha Tuttle
Excellent patient care with great professional staff & MD. As a Kaiser platinum member we were able to receive a fast comprehensive cosmetic consultation for only $125.
Kevin Li
I had my appointment with Dr. Lowenstein for Deep Fx CO2 laser treatment of acne scarring. In his bedside manner, Dr. Lowenstein was extremely kind, gracious with his time in answering my questions, and able to explain my treatment options very clearly so that I could make the best decision for me. He also performed excellent work on my areas of scarring (largely bilateral cheeks) which resulted in a favorable cosmetic outcome. While the scarring has not completely disappeared, the depth/degree of scarring is noticeably diminished. I highly recommend Dr. Lowenstein and his staff at California Skin Institute, all of whom are professional, courteous, and kind.
Tom Reed
Dr. Stefan Lowenstein is very nice and professional, made the diagnosis rapidly, and got my condition taken care of. Highly recommended!
Crystal Erlendson
Dr. Parnell and her nurses and staff are absolutely fabulous. I had a really wonderful experience coming to this office. They all have great energy and Dr. Parnell was wise, open, and connecting. I had some injections and laser done for some scarring as well as treatment for a cyst. I cannot say enough about the doctor and the team she has. I paid out of pocket since my treatments were cosmetic, and pricing was really fair. I am from the city, but would definitely make the trek for any of my cosmetic derm needs. I am so thrilled with my initial results and looking forward to coming back and continuing my treatments here. Highly recommended!
