Keira Greene DDS
Dr. Greene was raised in a military family and called many places home before graduating high school in San Antonio, Texas in 1991. She then attended the University of North Texas earning a degree in Geography in 1995. At that time, she had no idea she would later change career paths and eventually attend dental school in 2003, graduating from the University of Texas Health Science Center Dental School in San Antonio in 2007.
Since 2007, Dr. Greene has practiced dentistry both in private practice and in settings devoted especially to children’s dentistry. She enjoys all aspects of dentistry and is committed to providing quality, compassionate dental care to all her patients.
Outside of dentistry, Dr. Greene enjoys spending time with her family. She married her husband, Dr. Brandon Greene in 2003 and in 2011 their daughter, Riley, was born. They also have a bullmastiff dog that is also a big part (literally) of the family! Dr. Greene is excited to become part of the Tahlequah community and Premiere Dentistry of Tahlequah.

Lyndee F. Ailshie R.D.H.
I graduated from Fort Gibson High School in 1997. I then attended Northeastern State University in Tahlequah, Oklahoma. While attending college at NSU I served two terms as president of Tri Sigma sorority, and one term as a representative on the All Greek Council. I also participated on a Student and Staff panel with President Williams to improve campus relations. After graduating with my bachelor degree from NSU I then got accepted into the Tulsa Dental Hygiene Program. Upon graduating from Dental Hygiene School in May of 2004, I then started working for Premiere Dentistry in July 2004. I am married to Jeff Ailshie of Muskogee and we have one daughter, Layne Ailshie. I feel very blessed to be able to work in a profession that I truly enjoy. I have become very attached to Tahlequah and have been fortunate to build many strong patient relations with residents of Tahlequah.
Casey Scroggins has considered Fort Gibson and the surrounding communities her home since elementary school. After graduating high school in 2009, she earned an associate’s degree in Elementary Education. In May 2015 Casey graduated Dental Hygiene school at Tulsa Community College where she was awarded the Colgate Student Total Achievement Award. She finds joy working in a field where she can combine her love for children with her passion for other’s comfort and confidence in their smile.
Since becoming a member of Premiere Dentistry she has loved seeing the family-like bond the Doctors and staff share with the residents of Tahlequah. Casey, her husband Jesse, and their two Dobermans could not be more excited to continue to grow their family and careers near Tahlequah, Oklahoma.
I graduated from Wilburton High School in 2011 and I began attending Northeastern State University shortly thereafter. While attending Northeastern, I had the opportunity to be a part of the NSU Presidential Leadership class that provided me with the chance to grow closer to the Tahlequah community in a number of ways. I graduated from the Tulsa Community College Dental Hygiene Program in 2015 and I utilized my skills working in nearby Muskogee, Oklahoma, until I married in the fall of 2016. At nearly the same time as my marriage the opportunity to join the team at Premiere Dentistry came about, allowing me to serve in the wonderful community of Tahlequah providing quality dental care. My husband and I have two playful fur babies and we enjoy watching sports and spending time with family.
