Lisa PLisa Porter – Registered Dental Hygienist
My name is Lisa Porter and I am a Registered Dental Hygienist.  I graduated from Loma Linda University with a Bachelor of Science Degree in Dental Hygiene and have practiced in dentistry for over 30 years, specializing in cosmetic-restorative dentistry and periodontal private practice.  I worked for Dr. Stone several years ago and I am pleased to return here as my three children are officially raised and all three will be in college next year!

I live in Tustin Ranch, California with my husband Peter J. Porter and our 3 children, two dogs, one cat and several fish!  We are also visited frequently by my two great step daughters and two wonderful grandsons!

Practicing dental hygiene is a passion of mine.  I give my best to provide the highest quality of dental care and dental education and at the same time strive to be gentle and sensitive to each and every patient.  It would be my pleasure to help you meet your dental goals of a smile that lasts a lifetime!
