Founder & Owner

Marcus de Guzman, D.M.D.

Dr. Marcus de Guzman comes from a long line of medical doctors and dentists. He received his undergraduate degree from the University of Georgia in Athens, GA in 1996. Following in his grandfather’s footsteps, he decided to focus on dentistry and obtained his Doctor of Dental Medicine degree (DMD) from The Maurice H. Kornberg School of Dentistry (formerly Temple University School of Dentistry) in Philadelphia, PA in 2000 at the age of 25. After working as an associate dentist for other practices for 9 years, Dr. de Guzman realized his dream and opened Bayou City Smiles in 2009.

While in dental school, Dr. de Guzman was involved with many outreach programs and initiated programs such as dental and oral health screenings in local public elementary schools, HIV clinics, and even nightclubs. He was an invaluable volunteer at ASIAC (AIDS Services in Asian Communities) in Philadelphia, doing outreach not just in the Asian community but within the Philadelphia community as a whole.  His efforts towards public health were recognized in 2000 by the Association of Public Health Dentistry and he was presented the Community Dentistry and Dental Public Health Award upon graduation. He is also a proud recipient of the 2017, 2018, 2019 Houstonia Top Dentist Award.

To this day, Dr. de Guzman continues his passion for helping and giving back to the community, but now in Houston, TX. He volunteers his time, effort and expertise to various organizations and community programs. Among them, he had been a volunteer dentist for Bering Omega Dental Clinic, a non-profit clinic, from 2004-2010.  He also held a position as co-chairperson for two years, a volunteer position, for the Dental Assistant Training Program (DATP) for the Greater Houston Dental Society (GHDS).

Dr. de Guzman strives for excellence and keeps abreast with the current dental modalities.  He is an active member of the Greater Houston Dental Society (GHDS), the Texas Dental Association (TDA), the American Dental Association (ADA), the Academy of General Dentistry (AGD), the American Academy of Cosmetic Dentistry (AACD), the American Association of Public Health Dentistry (AAPHD) and is a Fellow of the International Dental Implant Association (IDIA). He has been practicing sedation dentistry since 2003 and is a certified provider of Invisalign and implants.

During his free time, Dr. de Guzman keeps in shape through CrossFit. He loves to entertain friends and family at his home and his favorite pastime is sitting at a local coffee shop with a good book to read.
