Trish Walraven is a dental hygienist, blogger, and software designer. After graduating Magna Cum Laude from Texas Woman's University, she spent almost 25 years practicing full-time clinical hygiene, including 5 years in the private practice of the Dallas County chief forensic odontologist, and 17 years in the office of Dr. David Rossen of The Colony, Texas, which was featured in a Dental Town office visit a few years ago. In 2008, Trish founded DentalBuzz, a dental trends website and blog, and in 2014, she and fellow Townie hygienist Erika Feltham collaborated on a DentalBuzz article about the blue specks that dentists and hygienists were seeing under patients' gumlines during recare visits. The news that these plastic microbeads were being added to toothpaste merely for color gained national attention, with their awareness campaign culminating the signing of a bipartisan bill by President Obama in December of 2015 to ban the sale and distribution of products containing microbeads in the United States.

Trish continues to write for DentalBuzz and is currently spending her time with BlueNote Software LLC, a medical intra-office communication company that works with dentists, optometrists, veterinary hospitals, and other medical specialties to help offices manage the workflow of their offices with virtual light panel systems.
