Tiziana Procopio, D.D.S.

I am originally from the city of Catanzaro, Italy. I graduated in 1992 with a dental degree, cum laude from the University of Messina, Italy. I followed with postgraduate work in 1993 at the University of Bologna (AEGD - 1 year program). I moved to San Francisco, California in 1998 and graduated from the University of Pacific dental school in 2001.

I worked in San Francisco for 2 years before moving to Walnut Creek in 2003 where I now reside with my two wonderful daughters and my wonderful husband. I provide all types of general and cosmetic denstistry services, but my specialties include Extractions and placing Implants.

In 2004 I completed a dental implant surgery curriculum at the Dental Implant Institute. I was personally trained by Dr. Lawrence Lum, a pioneer in the field of dental implantology and I earned certification for dental implant placement.I continue advanced implant training on a regular basis and I have successfully completed hundreds of implant cases in our office.

I feel very fortunte to work with Dr. Wolter and provide high quality dental care to both our incredible group of existing loyal patients and new patients as well.
