Today we want to take a moment to shout out Dr. Marie Lathrop, PCSO President-Elect!
.
We asked Dr. Lathrop what she enjoys most about being a part of the PCSO leadership team and her response was: "It is a wonderful group of hardworking people to be working with and I feel that my input gives a different perspective." And clearly ortho must run in the family, because her oldest daughter is also an orthodontist!
.
We appreciate everything you do, Dr. Lathrop!
