About Lawrenceville Orthodontists
Long-term families return here across multiple children for early phase 1 treatment with Dr. deMarsche, with results reported holding decades later.
Lawrenceville Orthodontists sees a striking number of young patients for early (phase 1) treatment, and reviews often follow families through years of care as multiple siblings move through braces or Invisalign. Results come up often and specifically, from a jaw surgery case that corrected a severe underbite to retainers still holding straight teeth 20-plus years on. Dr. deMarsche is described as precise and attentive to detail, coordinating even complex cases like surgical corrections with outside surgeons. The office also draws adults back for Invisalign, including some returning years after teenage braces shifted.

I went to Dr. Roberts when I was a kid, and my daughter just finished her treatment. Dr. Roberts was great with my daughter and very personable. The whole office staff is also friendly and helpful. Heather has been a lifesaver with all my needs for ny FSA requirements. I would recommend this office!

Good staff, no wait, even if you do have a wait they have a game room. But the actual treatment is questionable. Breaks a lot.

I had braces put on in 2023, and Dr. Roberts, and his staff were amazing! They did such a great job. I would highly recommend!

Loved my experience with Dr Roberts. I actually found him through the Invisalign website as a Diamond level provider rather than google reviews because it meant he specialized on this and had done it multiple times before. Very happy with my result and the whole staff are lovely to work with!

I just got my braces off and I couldn't be happier with my smile! It turned out even better than I expected. Dr. Roberts is amazing at what he does. The whole team is also so kind and welcoming. I highly recommend them to anyone considering braces!
