Kristi Leach-Espericueta, DA

Dental Assistant

Our treatment coordinator, Kristi, has been a part of the WinningSmiles team for 10 years. She is a graduate of the dental assisting program at 4-D College in Colton, CA.

Kristi loves that her job lets her help others and seeing the transformation in our patients’ smiles!

When Kristi isn’t at the office assisting our patients, she can probably be found spending time with her family.

Very courteous!
