When you think about improving your smile, the “where” matters just as much as the “how.” Spencer orthodontic treatment at Central Massachusetts Orthodontic Associates (CMOA) offers more than just great results—it gives you personalized, convenient care in a welcoming community. With two more offices in Worcester and Auburn, CMOA makes it easy to access high-quality orthodontic treatment close to home.
A Local Practice With Deep Roots
With over 50 years of orthodontic excellence, our practice continues to evolve while staying committed to what matters most: you. Our two doctors, Dr. Lisa Giarrusso and Dr. Gregory Livanos, bring decades of experience and board-certified training to the table.
Rather than needing to travel to a big-city chain for orthodontic care, you can stay right here in Spencer, Worcester, or Auburn and receive customized treatment from a small, highly-trained team that knows your name and your individual smile goals. It doesn’t get much better than that!
Why Choose a Local, Family-Owned Orthodontic Practice?
There’s something very special about seeing the same faces at every visit. From your initial consultation to the final retainer check, our team is focused on your comfort, trust, and results. Here’s why local care makes a huge impact:
- Continuity of care: You see the same doctor throughout your treatment, whereas corporate offices might bounce you between multiple providers and create confusion.
- Flexibility: Easier scheduling, closer follow-ups, and personalized adjustments.
- Relationships: We get to know your family and your lifestyle; you’re never just a number in our queue.
- Genuine recommendations: Some offices will try to steer you towards one treatment vs another to hit a certain profit margin. That is never our priority.
- Community support: Our team lives, works, and gives back to the same towns you do!
Choosing a local practice for your Spencer orthodontic treatment means you’re able to get the smile you want and support your own community all at once.
Your Choice of Treatment Options
At Central Mass Orthodontic Associates, we understand that every smile is different. That’s why we offer a wide variety of treatment options tailored to your individual goals, lifestyle, and comfort. Whether you’re a student juggling classes, a working professional with a packed calendar, or a parent seeking the best care for your child, we have a solution that fits.
- Metal Braces: These classic braces are more advanced than ever, offering efficient results and greater comfort. They’re a popular choice for patients of all ages and especially effective for more complex alignment issues.
- Clear Ceramic Braces: These braces blend with your teeth for a more subtle look, making them an excellent option for teens and adults who want a less noticeable treatment.
- Invisalign: Our clear aligner system is virtually invisible, fully removable, and easy to maintain. Invisalign fits seamlessly into your daily routine, letting you eat what you like and maintain your regular brushing and flossing habits.
- Advanced Technology: We use digital impressions (no more goopy molds!), laser therapy, and shape-memory NiTi wires for a more efficient and comfortable experience.
Your orthodontic plan at Central Mass Orthodontic Associates will be personalized just for you. Our doctors will walk you through each option carefully, so you can feel confident about your treatment every step of the way.

Board-Certified Experts You Can Trust
Orthodontics requires extensive training beyond dental school, and our doctors go even further. Dr. Giarrusso and Dr. Livanos are both board-certified, a distinction earned by fewer than half of all orthodontists.
Our doctors:
- Spent 11 years in higher education and clinical training
- Stay current with advanced treatment methods and technology
- Have experience in complex cases, surgical orthodontics, and care for all ages
