Learn More About Our Practice

I’m Dr. Day and I’d like to personally invite you to explore what makes our practice unique and special.

Meet Us

We want to invite you to join our dental family. Life is hard and a majority of people struggle coming to the dental office. As part of our dental family nothing is more important than your comfort. We offer a warm, friendly atmosphere where we can focus on your needs.

Meet the doctors

Dr. Elizabeth Day was born in Phoenix, Arizona, but shortly after moved to Boulder City, Nevada where she lived for her whole childhood. Boulder City is still home to her parents, and holds a very big piece of her heart. Dr. Day moved away to Reno, Nevada (Go Wolfpack!) for her undergraduate degree in Biology, and then returned to southern Nevada to pursue her doctorate in Dental Medicine at UNLV. Dr. Day loves to learn, and stays up to date on dentistry through continuing education. Dr. Day married her best friend Joe, and together they have a beautiful little girl named Holly. Their family would not be complete however without their three dogs Zero, Charlie, and Poppy. This past year has brought complete joy to their household when they welcomed their daughter, and so far have spent the year trying to navigate life after a baby is born. For the future though, Dr. Day has big camping and travel plans. In her free time, which is not a lot, Dr. Day enjoys refinishing old furniture to give it new life, and playing on the computer working with photoshop. “As my patient you can expect me to treat you as I would my own family. I will listen to you, address your concerns, and educate you on the best possible choices for your individual needs. I want my patients to leave feeling happy and confident about their dental choices!”

Meet the doctors

Dr. Trevor graduated from Concordia College – Moorhead, Minnesota in 2016 with an undergraduate degree in Biology and Chemistry. Following his undergraduate graduation, he went and worked as a dental assistant for his aunt and uncle (2 of his 5 relatives that are dentists!) for a year prior to attending the University of Minnesota School of Dentistry to earn his Doctor of Dental Surgery degree in 2021. He then uprooted to learn advanced dental techniques through a General Practice Residency at Colorado University – Anschutz Medical Campus, where he was asked to stay on as a chief resident. It is here that he developed a love for advanced endodontic, prosthodontic, surgical, esthetic, and implant procedures, all while staying focused on the overall health of the individual in his chair. Continuing his migration south, he is excited for the warmer weather that Las Vegas has to offer, and to be wearing less jackets and more sunscreen. Outside of dentistry, Dr. Grandgenett (“Dr. G” works too!) loves to cook, eat good food, snowboard, run, hike, play tennis, pickleball, and volleyball, and spend time with his golden retriever puppy, Gibbs. Growing up within a tight-knit family in the small town of Alexandria, Minnesota, Dr. Trevor appreciates and loves the welcoming atmosphere cultivated within the dental practice in Las Vegas. He firmly believes patients should be treated as his own family and that the treatment plans should reflect the goals we will achieve together. He is devoted to providing quality care for a variety of dental needs and continually strives for improvement through continuing education and mentorship. Dr. Trevor is a proud member of the American Dental Association and the Omicron Kappa Upsilon National Dental Honor Society.
