Marlen, Dental Assistant

Marlen has a tremendous appreciation for dentistry as it lets her combine her technical ability and hospitality to serve our patients in a truly unique way. Everyone deserves a beautiful smile, and to be able to be part of the dental process and change lives is really special to her. Her goal as a dental assistant is to make her patients comfortable and give them the best experience possible in our office.

Marlen’s dental career started while she was still in high school, during which she completed 900 hours of dental assisting. She went on to graduate from Barry Tech, and over the years, she has learned how to always be on the cutting edge of dental technology while delivering the highest level of treatment for every single patient. Today, she has training in dental photography, 3D printing and design, and is continuing to learn.

When she isn’t at work, Marlen loves to go to the gym, run, spend time with her dog (Coco), and see family and friends. She also enjoys reading, painting, cooking, riding horses, and watching movies.

Tiana, Dental Treatment Coordinator

Tiana started in dentistry at age 18, and she fell in love with helping others regain their confidence and self-esteem. She says that being able to give someone the ability to eat and smile again is truly awe-inspiring. Her philosophy on patient care and treatment is the Golden Rule--treat others how you would like to be treated. To ensure our patients have a positive and comfortable experience, she prioritizes clear communication, education, and a welcoming environment.

Tiana attended BOCES for dental assistant training, and she is currently enrolled at Farmingdale State College. She has previous experience in general dentistry, orthodontics, oral surgery, periodontics, endodontics, pediatrics, and prosthodontics. She says that healthcare is an ever-changing field that requires all involved to grow in knowledge, which is why she stays up to date by consistently reading accredited sources from the ADA (American Dental Association).

Outside of the office, Tiana’s hobbies include hiking with her dog, taking cycling classes, playing tennis in the warmer months, watching movies (comedies preferred), and learning (ex: languages).

Alexandra, Registered Dental Hygienist

Bringing over 15 years of experience to our team, Alexandra says that building relationships with her patients is the highlight of her job. She takes pride in creating a comfortable and trusting environment where they feel heard and cared for. Helping a patient through their dental anxieties is deeply gratifying because she knows she can make their experience more pleasant and positive. Overall, her work allows her to make a tangible difference every day. It’s more than just cleaning teeth; it’s about helping people lead healthier, happier lives.

Alexandra completed her dental training at Briarcliffe College, earning an Associate of Applied Science in Dental Hygiene. While there, she was on the Dean’s List and President’s List and was the recipient of the Compassionate Caregiver Award. Prior to joining us, she worked in multiple practices in New York alongside both general dentists and specialists.

Alexandra comes from a large Italian family, which she says greatly influenced her values and work ethic. Growing up, she helped her aunt with her candy store in the summer, and in the winter, she was with her mom who operated a mobile dental practice that provided care to underserved communities. Outside of dentistry, she enjoys gardening and travels as much as possible. Fun fact: She used to be a competitive figure skater and says this taught her a lot about perseverance and commitment.
