She walked into the office one day to bring her son for an appointment and walked out with a position as one of our own orthodontic assistants. With her passion for fitness she one day hopes to become the world’s strongest women.

Spencer has been a huge asset to our team and makes Dr.Newman feel a little less outnumbered. Other than his handyman skills he takes pride in his record taking and intraoral scanning skills. He won’t rest until all of our instruments are sterilized, packaged, and ready to use. When he is out of the office he is actually a DJ. His name is DJSL! Finally, he hopes to be an orthodontist and Dr.Newman’s boss by 2027.
Victoria is great asset to our clinical staff. She is super patient with our little ones and loves to make them laugh. She will also help you pick out the trendiest colors for your braces! While out of the office you can see her catching huge waves at Long Beach. With her love for the water she also has an amazing collection of sea shells! If you ever wondered why she is so calm, its because she loves yoga and believes everyone needs a little namaste in their lives.
Ariel always knew she had a passion for teeth when she found herself always staring at her own. She joined our practice hoping to gain some hands-on experience in the dental field and quickly fell in love with orthodontics.

Ariel is a huge super hero fan so if you want to get on her good side, tell her how much you love wonder woman!
