Get to Know Dr. Libby

Why did you decide to become a dentist?

I became a dentist because I have a knack for fixing things and have always enjoyed working through complex problems. In addition, science and technology have always been interests of mine. The fact that I get to wrap these into one profession to help change lives is a bonus and it brings me much happiness.

What do you enjoy most about being a dentist?

I enjoy the opportunity to help people find their smile; one that functions healthily and gives  them a better quality of life than what they previously had.

How would you briefly describe your patient care philosophy?

There is a solution to every puzzle. People from all walks of life come through these doors looking for answers where they thought there were none. Some cases are more challenging than others, but the ones we can help with will change lives for the better. I believe in providing comfortable  and compassionate dentistry to our patients, along with helping them solve the problems they have and/or don’t yet know about before they become troublesome.

Are there any particular moments in your career that stand out for you?

There is no greater moment than the look of a patient who has truly had their life changed for the better. I don’t have just one moment, but I carry the many moments like this to drive myself forward because I want to change the world one smile at a time.

What do you feel are some of the most significant breakthroughs in dentistry—and what do you look forward to in the future?

The improvements in technology, such as Invisalign®. As an Invisalign® provider, I have had the opportunity to improve the function and aesthetics of patients coming through our doors. I look forward to the days when we can use technology to provide dentistry in ways we do not yet know or may not have come across. There is much room for growth and a bright future ahead.

What’s the top advice you have for someone who is looking for a dentist?

Be selective and communicate openly. There are many dentists out there and we hope we can be a good fit for you. Open communication is a great way to build trust and trust is not something we expect to have immediately, but we would love the opportunity to build that bridge with every single person who comes through our doors.

How Would You Describe Working at Saco River Dentistry?

This is the environment that I enjoy, which is not just an office, but a second home. The team of people I work with and the patients are family here and we all work hard to keep it that way.
