Meet the Doctors

A visionary dentist, a devoted wife and mother, a trusted friend

She has a kind, compassionate heart for patients & is committed to remaining on the leading edge of dentistry. Dr. Ashley most recently graduated from the highly-prestigious Kois Institute & is a proud & active member of the American Dental Association, California Dental Association, Sacramento District Dental Society, American Academy of Cosmetic Dentistry, Academy of General Dentistry, & Doctors for Oral Conscious Sedation.

Since opening Smile & Co.’s first location in 2017 with a mission to provide an exceptional dental experience for families throughout the Folsom area, she’s been on Sacramento Magazine’s Top Dentists list three years in a row.

Dr. Ashley Joves quite literally grew up in the dentist’s office. Her mother, a single parent who immigrated to America from the Philippines, would bring her along to practice after practice. She spent her days coloring in break rooms or observing the strong, one-on-one relationships her mom cultivated with patients.

She always knew dentistry was her calling and after graduating dental school with honors from NYU, she completed a highly-competitive one-year general practice residency at Abington Memorial Hospitalin Philadelphia.

Now, as she opens the Smile & Co. Smile Design Studio in Roseville, her three little boys who also grew up watching their mother practice dentistry get to witness her achieve her wildest dreams.

She hopes to inspire them and hopefully you, too.

“The heart of Smile & Co. is my amazing team. They bring the joy, they bring the energy, and I am so grateful for each and every one of them. These women helped make my dreams come true.”
