Learn Who We Are

  • Erik Celis

    Behind every telephone call is a patient or family member with a different need, and behind every need, there is an opportunity to bring on a smile...this is the motto that I stand by. Since graduating from Montclair State University, I have over 7 years of experience in healthcare customer service, and I have been a team member of this practice since 2018, greeting our patients as they come through our front door.

  • Dr. Peter K. Eng

    Dr. Peter Eng received his degree in Doctor of Dental Medicine (DMD) in 1988 from the Boston University School of Dental Medicine.  He finished in the top 5% of his class and went on to complete a residency in Advanced Education in General Dentistry (AEGD) in 1989 and earned his Certificate of Advanced Graduate Studies (CAGS). During his spare time, Dr. Eng enjoys a great movie or taking a mini-vacation. His favorite spot is Boston, MA where he gets to catch up with his children. Dr. Eng is also a car enthusiast and loves watching car restoration shows. 

  • Pilar A. Celis

    I’m proud to work in an office that provides high quality dentistry. My favorite part of my job is to make patients comfortable during treatment and make sure they leave with a smile. I earned my degree from NYU in May 2012. I have prepared myself to become a RDH because I want to educate patients about the importance of proper oral hygiene and prevention of oral diseases. I have been a dental hygienist at MLDA since July 2012.

  • Patricia Fuentes

    I joined Mountain Lakes Dental Associates as a temporary Assistant, and from the moment I arrived, Dr Eng made me feel like a part of the team. I highly value the honesty, dedication and care given to each patient here. I have many years of experience in the dental field and this practice fulfills all my professional expectations. I am so happy utilizing my skills to take care of our patients and make them as comfortable as possible.

    During my free time I enjoy spending time with my family as well as enjoying nature with my granddaughter!

  • Ellen Liu

    New to the world of dentistry, I joined the team at Mountain Lakes Dental Associates as Office Coordinator.  I look forward to meeting you.  You can count on me to be there to greet you when you arrive, answer questions, and schedule your next visit before leaving the office with a smile.  In my spare time, I'm always looking forward to spending it with my children. We enjoy traveling, bowling, painting, and mostly spending an afternoon at the movies.

    Dr. Eng is absolutely the best dentist I have ever experienced. He is kind, personable and takes time with his patients to guarantee you understand procedures and next steps. He will do everything in his power to save a tooth but he is not a tooth fairy. Extraction is a last resort. I appreciate and admire Dr. Eng & his dental skills.

    P.S. He also has a great staff who emulate his kindness.

    Donita J.

    Dr. Eng has been my dentists for years; He is by far the best dentist I have ever known. Dr. Eng is very talented; he explains in details the procedures to be performed and recommends preventive measures. I had very bad teeth and he manged to fix all my dental issues.

    Bassel D.
