As an administrator, I love the challenges of helping patients achieve their desires of a beautiful smile without facing any financial difficulties. With over 35 years of experience in the dental field, I find sharing the changes with our patients one of the greatest rewards possible. I believe in the old saying of treat a patient as you would treat your family". Each one is special to me. I am a proud military mom, my daughter Megan is a Sargent in the Marine corp. while my other daughter Katie is a nurse. I have taught my girls to give to our community and country. I am an avid reader and crafter and enjoy those things on the weekend. You can always ask me what project I have going and there is always 2 or 3 in the works.

Irene De Leon – Treatment & Insurance Coordinator/Dental Assistant


I was born and raised in the small town of Waller, TX just outside of Cypress. I enjoy exploring Houston’s art galleries, museums, parks, and of course all the delicious food. I am a proud bun mom to a 7 year old Holland lop rabbit that I am obsessed with and love showing him off! 

As a dental assistant, I love helping patients smile. Whether it be a smile makeover or a simple procedure to help them get out of pain, it warms my heart to witness them walking out of the office showing off their beautiful smile. I also enjoy helping patients understand and get the maximum benefits from their insurance. I strongly believe good quality dental care should not just be in the chair but in the entire office. I will always strive to have patients leave happy about their smile and confident that their insurance benefits are being used to the maximum.

I look forward to seeing you in the office soon!

People say the eyes are the windows to the soul. I like to say that the mouth is the window to hygiene. I chose to become a dental hygienist because I have always been fascinated by teeth and helping others. Teeth has always been the first thing I noticed when meeting someone new. And what better way is there to help someone than to help them improve their overall health all while helping them achieve a more beautiful smile.

As a dental hygienist I proudly devote my time, knowledge, and skills to the individual and the community alike. I will continue to use and seek the most effective and efficient therapies to incorporate into my standard of care. I will maintain a healthy, friendly, and respectful professional attitude that not only represents myself but also the dental hygiene profession overall. A goal of patient education, disease prevention, and community service is what I strive to achieve – all while collaborating with Dr. Mammen in an effort to improve your overall quality of health. I am look forward to meeting you very soon!

Maria Font – Dental Hygienist

Maria Mint Final 2

I have lived in Katy, Tx for over 16 years, but grew up in Venezuela.  Since, I was twelve years old I wanted to be a dentist.  To pursue my dream, I attended dental school at the Central University of Venezuela, where I received a Doctor of Dental Sciences (DDS) degree in 1996.  After practicing in Venezuela for a few years, my husband was transferred to Houston.  I then decided to go back to school and study something related to dentistry because that is my true passion.

In 2013, I received my Dental Hygiene AAS, from HCC Coleman College for Health Sciences, where I graduated with the Highest Honors.  I am a member of the American Dental Hygienists’ Association, Greater Houston Dental Hygiene Society, and The National Society of Collegiate Scholars.

I am excited to be back at Mint Family Dental with Dr. Mammen and the team.  It is a pleasure to work with Dr. Mammen because honesty, perfection, and excellence are the core values of our practice.  I enjoy getting to know my patients individually and to provide the highest quality of dental care.

I really look forward to meeting you or seeing you again!
