Video Testimonials

Our patients say

The staff is so friendly and I love the reminder text about your appointment the next day. I opted for Invisalign and they seem to be faster than most with more of a three week turnaround than a month so I got started sooner than I thought!

Christy

Dr.Marshall and the entire staff are excellent in every aspect of my dental needs. They are very professional, accommodating, informative, and friendly. I will continue to come here, and recommend to friends/family.

Andy

I can't speak highly enough about the staff, the location and the quality of service I have received at Dr. Marshall's office. I recently completed my Invisalign treatment and not only was the process seamless but it was also a pleasure interacting with the staff.

Colleen

I had a great experience here as a first time patient. The staff were all very kind and helpful. The facility is clean and well kept. My dental hygienist explained everything to me as she went along. Dr Marshall also provides Vivera retainers which I was looking for as well.

Jess M

I was treated with so much respect, kindness, and patience. This was an awesome experience that started when I entered the office, and ended as I was walked to the door to exit. I'm very grateful for the care that I received.

Janice K

I didn't have any interaction w Dr Marshall herself. The stars are for Mustafa who was gentle and thorough beyond ant expectation with the teeth cleaning. The office manager was good also.
