Lulu - Registered Dental Hygienist

Lulu became a registered dental hygienist in 2019, and had been passionate about the dental field from her high school years. She got her bachelors at SDSU and then continued on to get her dental hygiene license. Lulu goes beyond routine cleanings, ensuring each patient's teeth receive personalized care. Her commitment to dental health shines through, making every visit a positive and comfortable experience.

One of my greatest passions is being able to help people. I love educating patients to help them understand more about their body in order to improve their oral health. I keep up on updated dental knowledge not only by attending continuing education, but also by doing a lot of my own research and being a part of dental groups that actively discuss and educate on all things dental! Besides being ultra passionate about dental health, I've enjoyed a multitude of hobbies which I'd be happy to share with you!

Lisa B - Registered Dental Hygienist

I am originally from Toledo Ohio and grew-up in San Diego. I graduated from California State University Long Beach with a Bachelors of Science Degree in Community Health Education. I then went on to complete a Bachelors of Science Degree in Dental Hygiene from Northern Arizona University. With 21 years of Dental Hygiene experience I find it to be an honor and a privilege to work for Dr. Marsh. Being a part of an outstanding team of dental professionals, I see great value in staying current in my profession by attending dental seminars and conventions.

My greatest joy is working alongside my patient by guiding, educating, and motivating them to achieve oral and overall good health. In my spare time I enjoy all that San Diego has to offer including hiking, sailing, swimming, gardening, going to church, and jazz concerts.

Marissa - Dental Assistant

I have been a dental assistant for over 12-years, starting my career in Santa Barbara, CA. Since then I’ve become an RDA and I’m continuing my education at Mesa College. My goal as Dr. Marsh's assistant is to provide a positive attitude and to make our patients feel comfortable and at ease. I am so thankful to have found such a fun and rewarding position at Hillcrest Dental Arts and to be a part of Dr. Marsh’s amazing team. In my free time, I enjoy activities with friends and family including hiking, being outdoors, animals, movies and live music.
