Dr. Dena Marcus

Growing up on Long Island, New York, I often worked as a dental assistant for my dad, who was a general dentist. His plan for me to follow in his footsteps eventually worked, first I pursued my dream of a career as a photographer. I attended the School of Visual Arts and graduated with a B.F.A. in Photography in 1994. I specialized in documentary and portraiture. While freelancing for various magazines, I came to San Francisco on an assignment. I realized instantly that I belonged in Northern California and decided to move out to San Francisco. After working as a photographer and supplementing my income with temporary jobs, I landed a position at the University of California San Francisco Dental School. I ultimately decided it was time to return to school and become a dentist. I graduated in 2003 from the University of the Pacific Dental School (now known as Dugoni School of Dentistry).

In 2008 I took over for a retiring dentist Dr Chistopher Neal.  I enjoy practicing in Sonoma and in 2012 was able to expand and remodel the office.  I strive to provide my patients state of the art dental dental care in a comfortable environment.  The office has the latest technology including one day crowns and a cone beam ( three dimensional x-ray).

Sonoma is not only one of the most scenic locations with great access to the city, mountains and beach but it is a wonderful community.  Over the past 12 years my staff and patients have truly become like family.  The past couple of years this community has had to come together to deal with many challenges.  The fires, blackouts, and now Covid-19 has changed the way we live and work but has only made our community tighter.  As we all face these challenges together my commitment to creating a lifetime of oral health to my patients only deepens.

I live in Sebastopol with my husband, goats, donkeys, chickens, cats, sheep and a dog.  The office is also decorated with my animals.  When I’m not working I spend time gardening, hiking, swimming, and taking care of the animals.

Dr. Alice Huang

My name is Dr. Alice Huang, and I am honored to introduce myself as the new associate dentist of Dr. Dena Marcus.  It is a privilege to be joining her practice, and I look forward to knowing you!  
I grew up in Stockton, California and stayed in my hometown to complete my undergraduate studies at the University of the Pacific.  Excited to experience the city life, I then moved to San Francisco to attend the Arthur A. Dugoni School of Dentistry.  After earning my D.D.S., I ventured out of California to the Pacific Northwest, pursuing advanced training in general dentistry at the VA Medical Center in Portland, Oregon.         
While I am new to beautiful Sonoma County, everyone I have met here has welcomed me with open arms.  I am beyond grateful to be in this profession and a part of our dental community.  It is deeply important to me that our patients feel comfortable, informed, and confident in the care that they receive.  When I am not practicing dentistry, I enjoy cooking, finding the best cheap eats in town, doing Pilates, hiking, reading and watching comedy shows.    


With the global pandemic and relentless wildfires, 2020 has presented incredibly challenging times for the Northern Bay Area.  While my heart is heavy, I am moved by the perseverance and resilience of our community.  No matter the circumstances, Dr. Marcus and I are here to serve your dental needs.
