Dr. Guy Mancuso brings over 20 years of experience and enjoys seeing people of all ages.  Helping Poway dental patients become aware of their dental health, improving smiles, and offering gentle care are his number one priorities.  His dental interests and professional expertise are centered around cosmetic dentistry; there are many beautifully restored smiles in our Poway community that are a result of his skills.  Creating natural smiles with Invisalign in the Poway area has been a large part of his practice since 2001; he has been a Poway Invisalign “Premier Provider” since 2005.    Dr. Mancuso has also been recognized by his peers as a “Top Dentists” as featured in the San Diego Magazine.

  • Following graduation, Dr. Mancuso practiced dentistry for 7 years in Colorado Springs, Colorado. However, after too many cold winters , he decided to return to his native Southern California where he has been since 1988.  He enjoys staying current with advances in dentistry by regularly attending seminars and study groups. 

  • Away from the office Dr. Mancuso enjoys cycling, sailing and scuba diving.  If you enjoy cycling, you might see Dr. Mancuso on the road or on one of Poway’s local trails.
