Dr. Kasia Marelich

I am originally from Poland where I was born and spent most of my childhood. I immigrated to the United States with my parents when I was 15 years old. I was extremely lucky to be surrounded by wonderful people who helped my family start a new life and guided me towards higher education. I graduated from Dartmouth College with a degree in mathematics and a minor in studio art. Dentistry turned out to be the perfect way to blend the analytical and detailed part of my personality with my eye for beauty and balance.    

After two years of working at a small dental practice in Cambridge, MA, I enrolled at Tufts School of Dental Medicine. These were very eventful four years: I made friendships that later would become crucial in my career as a dentist (Dr. Laura!) and I met my husband, Nate. After graduation in 2012, I entered a General Practice Residency at the VA Hospital in Palo Alto, CA, providing dental services for our veterans and expanding my clinical skills. While living in the South Bay, Nate and I visited Dr. Laura in Santa Rosa and we fell in love with Sonoma County. We moved here soon after our son was born in 2015.  Serendipitously, Dr. Laura and I worked as associates at the same dental practice, which we then purchased and named Santa Rosa Dentistry. 

When I am not a dentist I am a mother to my two beautiful children, Jacob and Julia.  I love watching them grow and become more independent every day.  I enjoy bike riding with them, going on hikes, reading an enormous number of books and watching Disney movies with them.  When alone, I love running on the beautiful Sonoma County paths and doing yoga, both of which serve me as a way to center and refocus. I am also an avid reader and you can always ask me what I am reading right now.  

I am passionate about dentistry and education. I attend over 75 hours of Continuing Education each year.  My focus is prevention of disease and I want every person to be empowered in their dental health.  I love creating beautiful, natural looking smiles and giving people confidence to conquer their world.  I am very excited to be a part of your journey!
