Marc Geronimo, D.D.S.
General Dentist

While studying at New York University’s College of Dentistry, Dr. Marc Geronimo was motivated by a special quote: “The block of granite in the path of the weak becomes a stepping stone in the path of the strong.” Today, he balances his General Dentistry practice with a leadership role in the local community, such as member of the Pre-Professional Health Committee at SDSU and speaker at various high schools on the topics of Dental Awareness and Professionalism, and continues to use this quote as inspiration to overcome fears and obstacles.

 As a dentist, Dr. Geronimo builds strong relationships with his patients – he truly enjoys providing excellent care to help people get out of pain and improve their smiles and oral health conditions. He is a member of several professional organizations, including the San Diego County Dental Society.

 Dr. Geronimo is proficient in Tagalog. In his free time, he enjoys working out, spending quality time with his family, and watching football – he’s a big San Diego Chargers fan!
