Julius S. Mascardo, D.M.D.


Dr. Julius S. Mascardo graduated with a Doctor of Dental Medicine (DMD) degree — Best Clinician recognition, from Southwestern University in 1984. After spending 10 years as Chief Dentist for Marsman Plantation Hospital and building a reputation for cutting edge, high-quality dental work, he then set up a private practice in Sto. Tomas, Davao del Norte, where he remains to be the top practicing dentist in the area. Today, he also maintains a clinic with his wife and partner, Dr. Eileen A. Margaja-Mascardo, in Davao City.

In 1995, Dr. Julius pioneered in bringing Oral Implantology to the Southern Philippines. At a time when the popularity of Dental Implants was at its infancy, he underwent an ICOI (International Congress of Oral Implantologists) Training Course in Singapore, learning with the best specialists in the field from all over the world. He then became one of the first to offer Dental Implants in Davao City. He now works hand-in-hand with Dr. Eileen in providing the highest quality of Implant and Surgical care for their patients .

His love for travel and learning has brought him to undergo numerous Continued Professional Development studies and Post-Graduate training courses with esteemed leaders from all fields of Dentistry, both locally in the Philippines and abroad, in the United States of America, France, Switzerland, Liechtenstein, Hong Kong and Singapore, to name a few.

Dr. Julius genuinely loves what he does and is well-known for specializing in complex surgical procedures, executing them in a highly-efficient and effortless fashion. To say that he is good with his hands would be an understatement. The patients especially love his painless, “don’t-feel-a-thing” anesthetic techniques, inducing profound anesthesia even on “difficult” or “resistant” teeth. This skillful expertise, honed by 30 years of experience and training, has become one of his professional trademarks.

Although already “established” by many accounts, Dr. Julius does not rest on his laurels, as he continuously strives to reinforce his knowledge by staying up-to-date on the latest and the best innovations that Dentistry can offer.

Eileen A. Margaja-Mascardo, D.M.D.


Dr. Eileen A. Margaja-Mascardo was a consistent dean’s lister and graduated Cum Laude, at the top of her class, with a Doctor of Dental Medicine (DMD) degree from Southwestern University in 1984. Upon passing the National Dental Licensure Examinations, ranking at the top percentile nationwide, she set up a private practice in Davao City with her sister, Dr. Phoebe A. Margaja-Sarabia.

Dr. Eileen is a multi-awarded dentist in the field of Orthodontics (Braces), garnering numerous recognitions for clinical and academic excellence. Upon completion of a Post-Graduate Course at the Asian Center for Orthodontic Research & Special Studies in 1996, and graduating at the top of her class, she was awarded with all four distinctions: ‘Best Clinician,’ ‘Best in Case Presentation,’ ‘Best in Wire Bending’ and ‘Best in Treated Case.’

Following this milestone, she was bestowed a highly-coveted immediate Fellowship into the Philippine College of General Practitioners in Orthodontics (bypassing both Associate 1 and Associate 2 levels) – an impressive feat and a first in the history of the organization.

Another of Dr. Eileen’s specializations is Cosmetic/Esthetic Dentistry, which she has been practicing since the 1980s. Borne from a family of medical practitioners and national artists, this affinity for esthetics comes naturally to her. She obsesses over the littlest of details, making certain that she produces no less than the best. She is known for realistic/natural-looking restorations, veneers, crowns and dentures, employing only the latest techniques and the best materials available.

In 2010, Dr. Eileen also took an interest in Dental Implants and underwent a Post-Graduate Course in Oral Implantology. Upon completion with flying colors, she now works hand-in-hand with her husband Dr. Julius, a pioneer in Implantology in the Southern Philippines, in offering the highest quality of care for their patients.

Dr. Eileen takes numerous Continued Professional Development studies and Post-Graduate training courses year after year, learning with renowned leaders from all fields of Dentistry, both locally in the Philippines and abroad — in the United States of America, France, Switzerland, Liechtenstein, Hong Kong and Singapore, to name a few.

She is well-known for her congenial nature and charming, gentle persona. Even with a staggering history of achievements, she remains to be a genuinely simple woman who holds no high airs and is a friend to all. She is a multi-tasker by nature and enjoys the pressures of juggling many endeavors at once. She is often called a jill-of-all-trades, and a master of almost all as well.

Kathleen Chloe M. Mascardo, D.M.D., D.D.S.


Dr. Kathleen (Kat) Mascardo combines the strength of both of her parents, carrying the same standard of care and clinical excellence she was raised to uphold. In 2013, she graduated with a Doctor of Dental Medicine (D.M.D.) degree at the top her class and was bestowed a “Special Recognition Award in Clinical Dentistry” from the Davao Medical School Foundation (DMSF). Soon after, she placed 6th out of nearly 1,000 examinees in the National Philippine Dental Board Examinations held in December 2013. After a year of practice as an Associate Dentist and as an Instructor of Oral Medicine at her alma mater, Dr. Kat decided to pursue further studies in the United States in search of higher learning and advanced education in Dentistry.

She was accepted in the highly-selective Program for Advanced Standing Students (PASS) at the renowned ivy league school, the University of Pennsylvania and graduated with her second D.M.D./D.D.S. degree, again at the top of her class in 2019, with a multitude of honors and awards, including:

  • Honors in Clinical Dentistry
  • Quintessence Award for Clinical Achievement in Periodontics
  • Louis I Grossman Award in Endodontics
  • PASS International Dentist Award
  • Omicron Kappa Upsilon Honor Society

An induction into the Omicron Kappa Upsilon (OKU) Honor Society, the oldest and most prestigious dental honor society in the world, is a privilege reserved for only the top 10% of graduating students. We are very proud of Dr. Kat for this recognition: proving that Filipino dentists can excel on the world stage.

Inspired by her father, Dr. Kat has taken her training a step further, and chose to specialize in the field of Periodontics and Oral Implantology.

With unwavering determination, she was accepted into the most competitive 3-year Periodontology program at the Harvard University School of Dental Medicine in Boston, MA, USA. At Harvard, she will train under some of the best clinicians and world leaders in the field of periodontal surgery and implantology. This unparalleled achievement is something that has never been done before and she holds the honor of being the first and only Philippine-trained dentist to matriculate at the Harvard Dental School. We are so proud of everything she has achieved so far, and continue to look forward to whatever future groundbreaking work she does next.

While at Harvard, Drs. Julius and Eileen will continue to collaborate with Dr. Kat on their implant, periodontal, and prosthodontic cases. She will also be available to perform surgeries in Davao City for certain periods of time during the year, and by request. Once she is done with her studies at Harvard, Dr. Kat hopes to pay it forward and give back to her hometown of Davao City and its people.

Aside from her achievements as a dentist, Dr. Kat was also a varsity soccer player, artist (sketching and sculpting), and writer for the school paper. She is still heavily involved in writing and counts traveling as one of her passions. She has a great love for travel and learning different cultures, but an even greater love for food and trying out different cuisines.

Dr. Kat is also passionate about charitable causes for persons with disabilities (PWDs), particularly the blind, and abused women and children. She has organized charity missions for the Davao School for the Blind and the SPMC House of Hope (Center for Kids with Cancer). She aims to give a voice to the weakest among us and put a face to PWDs: to elevate their cause and to empower people into believing that the capacity for human resilience has the power to overcome great adversity.
