It is with excitement and gratitude that I join the Ashtabula Dental Associates team! I was born and raised in the city of Ashtabula where my father has worked for 45 years as a train conductor for CSX and my mother has worked for After School Discovery since its conception. I was a 2010 graduate of Lakeside High School. After high school I went on to attend Marietta College in Marietta, OH where I studied biochemistry and played varsity womens soccer for 4 years, graduating in 2014. This brought me to Columbus where I attended The Ohio State University College of Dentistry, and graduated with my D.D.S in May 2018.

I am no stranger to Ashtabula Dental Associates as this has been my dental home since I got my first tooth Dr. Seymour as my family dentist, Dr. Forsberg as my orthodontist, as well as patient to many of the outstanding hygienists. Growing up, Ashtabula Dental Associates was always a friendly and comforting place to be and from these experiences, I declared that I wanted to be a dentist at the ripe age of 8 years old. Once I shared this revelation with Dr. Seymour, he went on to provide me with exceptional mentoring and allowed me to shadow him throughout high school and college. This community has truly shaped me into who I am and has given me a great support system, hard work ethic and appreciation for working in a small community. I am proud to re-join the community of Ashtabula and provide dental care to so many of the hard-working individuals and families that I have grown up around.

In my free time you can find me enjoying anything outdoors-- whether it be skiing or perch fishing on Lake Erie, playing soccer or playing with my golden retriever, Zelda. Professionally, although I am waiting to find my particular niche, I appreciate every aspect of general dentistry and family dentistry is always an area that I wanted to pursue. I truly enjoy treating all ages and I aim to provide the best dental care possible. I have most recently held the position of student team dentist for Ohio State Athletics, (providing preventative and emergency dental care and making mouthguards for their athletes) and I am certified in Invisalign orthodontics.
