Meet the Team


Shanna Bostrom 

Financial, Insurance and Appointment Coordinator

I work with our new patients to coordiate treatment plans and financial arrangements. I try to always make myself available to answer any question you may have to make your time here as pleasant, comfortable, and as stress-free as possible. Getting to know our patients is the best part of my job, I love to know what is going on in their lives. I have been in the orthodontic field since 2005. I am married with three daugthers, two dogs, and a goldfish. I like to coach soccer and softball, enjoy camping, going to Zumba class, ATV riding, and watersports. 



Clinical Assistant and New Patient Coordinator

I am here to guide every new patient through the process of becoming a patient in our office. I take records (X-rays and study models), call insurance companies, and help in the clinic as a chairside assistant as needed. I am very passionate about what I do; I truly care about each and every person in our office. I love meeting new people and helping them achieve their goals of a healthier, more beautiful smile.


Vickie Hunter

Clinical Assistant

I have over 32 years of experience in the dental field, and have happily spent the last 18 here, helping patients achieve great smiles at San Leandro Smiles! Being here for such a long time has allowed me to really get to know many families in our community. I love watching as a new patient progresses through treatment and ends up with a new, beautiful smile!

I am married with two daughters and step children. As a devout Christian, I share my religious beliefs with the community by door to door witnessing. When I have free time, I enjoy reading, watching movies, and entertaining family and friends.

Erika Cortez

Clinical Assistant

I work alongside Drs. Sexton and Ung, assisting in all aspects of patient care, including placing and removing braces, and taking X-rays and impressions. I get to watch our patients’ smiles be created from beginning to end, and the results are always worth all the hard work! The happiness a new smile can give is something truly remarkable.

I have three children: Ricardo, Adryanna, and Alejandra. I enjoy watching a good movie, whether I am at home snuggled up with the kids or at the movie theater with popcorn! I also love chocolate! My favorite sport is baseball; go A’s!
