Brenda Colarossi - Office Manager

Hello, my name is Brenda, and I have been in the dental field for over 25 years.  I started working side by side assisting the doctor as a chair-side assistant and from there moved to the front office taking care of the insurance billing and treatment coordination. 

Eventually, I obtained the Administrative position, managing all aspects of the front and back department where I take full responsibility to ensure that our patients experience the utmost Dental Care in a professional and caring environment.

On my spare time I enjoy very much spending time with my family and cooking yummy Italian recipes for them.





Olga Zemshman - Registered 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.

My goal is to continue providing with Dr. Aghakhani and team of professional staff, the best Dental Care possible where True Care, Compassion, Education and Communication will always be my mission.

I truly enjoy my time with my husband, family and friends, always looking forward spending extra time and loving each and every one of our grandchildren. 


Shelby Crandell - Registered Hygienist

I have been a Hygienist for Focus Dentistry since 2004. All together, I’ve been in dentistry for 16 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 - Registered 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 Extended Function (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.
