Meet the Staff

Brenda Colarossi - Office Manager

Hello, my name is Brenda, and I have been in the dental field for over 20 years.  I started with assisting the doctor and moved to the front office taking care of insurance billing, and treatment coordination.  Eventually I attained the Office Manager position.  In this position I take full responsibility to ensure you receive the best dental care and experience.

On my spare time I enjoy spending time with my family and cooking our yummy Italian recipes. 





Olga Zemshman - Hygienist

 Hello, my name is Olga.  I graduated Taft College Dental Hygiene with greatest honors in 1998.  One of the things about dental hygiene is the ability to provide the best care for my patients by utilizing my clinical skills.

The bigges reward of my everyday work is knowing that patients receive the highest quality dental work while being comfortable throughout the experience.

Outside the office I enjoy being a parent and spending time with my daughter.  I have a passion for art and traveling.

On my free time I enjoy spending time with my son.


Shelby Crandell - Hygienist

I have been a Hygienist for Focus Dentistry since 2004. All together, I’ve been in dentistry for 14 years. I started out as a dental assistant and then realized that dental Hygiene was my niche.

In my free time, I enjoy wine tasting, movies and traveling with my boyfriend, Donny. Of course, I can’t leave out spending play time with my dog, Nikki, a Papillon born in 2005.


Natalee Williams - Hygienist

Natalee has been in dentistry since 1989. She is a graduate of West Los Angeles College and is a member of the Dental Hygiene Honor Society. She became a member of the Focus Team in March of 2007.

Natalee spends her time off Golfing and going to Laker games. On many weekends you can find her with her son Sean, bicycling and enjoying the outdoors.


Larry Miranda - Registered Dental Assistant (RDAEF)

Hi, I am Larry.  I have been a dental assistant for the past 21 years.  In 2002, I went to UCLA to obtain my RDAEF license, which gives me the ability to do more invasive procedures with my boss and piers. 

I love educating all the patients and going the extra mile for them. 

In my off time I spend it with my family and friends on the soccer fields.
