Meet Our Team

We are happy to introduce you to the Hancock Dental Center team! Dr. Josh and his team always provide a gentle, caring, and compassionate approach to dental health. You will truly appreciate our exceptional care and how our team makes you feel like family!

Joshua Hancock, DDS

Joshua Hancock, DDS 

In 2003, Dr. Joshua Hancock established Hancock Dental Center in his hometown of Martinsburg, WV. A graduate of Martinsburg High School, Dr. Josh (as he’s better known to his patients) continued his education at West Virginia University (Let’s go Mountaineers!) completing his Bachelor of Sciences degree and ultimately earning his Doctor of Dental Surgery degree in 1999.  After graduation, Dr. Josh completed a hospital-based residency in general practice through the Veterans Health Administration Hospital in Hampton, Virginia.

Outside of dentistry, Dr. Josh enjoys spending time with his wife, Kathy, and their two sons. They manage to keep him busy, but he does find time to enjoy fly fishing (especially with his father) and cheering on the Mountaineers! (We won’t mention the Redskins…maybe next year!)


Treby Hoak, RDH Treby Hoak, RDH

Treby supports Hancock Dental Center as both our office manager and as a dental hygienist. She started her career in dentistry over 12 years ago as an orthodontic and general dentistry assistant and eventually went on to dental hygiene school. Since her 2009 graduation (alas not from WVU but Dr. Josh and the team have decided to let that slide!) she has worked in private practice as well as for the federal government and department of defense. Treby also has significant experience in the administrative aspect of dentistry. As the HDC office manager, she keeps the day-to-day operations running smoothly. This role is the perfect combination of her passions: dentistry and management (all to the benefit of the Hancock Dental Center patients!)

Treby leads an active lifestyle outside of the office. She loves spending time with her son and 3 dogs.  Not a native of the area, Treby is still exploring and learning what West Virginia has to offer (often finding things that our local team members have overlooked!). She enjoys exercising, hiking, kayaking, camping, snowboarding and horseback riding.

Olivia has a bachelors degree in dental hygiene from West Virginia University. Born and raised in West Virginia, Olivia has always hoped to start her career in her home state. Originally from Fairmont, Olivia moved to Harper's Ferry during the summer of 2016 to join our team.  

In her free time, Olivia enjoys all outdoor activities including hiking, camping, and kayaking. She also enjoys traveling and hanging out with her dog and new kitten. She always looks forward to WVU football and basketball seasons. Let's go Mountaineers!

Bekah grew up right here in Martinsburg, WV. She attended Martinsburg High School and graduated in 2007 from West Virginia University with her bachelor’s degree. While she loves her Mountaineers, Bekah definitely loves being back in her hometown (it’s not too far to catch a WVU game when the opportunity arises!) Bekah has been working as a dental assistant since 2012 and joined the team at Hancock Dental Center in February 2016.

Bekah enjoys traveling, being outdoors, working with animals, and spending time with her friends and family.



Sarah Charles, Patient Treatment CoordinatorSarah Charles, Patient Treatment Coordinator

Sarah’s is the friendly face (and voice) you’ll find at our front desk welcoming you to Hancock Dental Center! Originally from Winchester, VA Sarah brings a background focused on customer service. She obtained her cosmetology license in 2010, but was inspired by the dental field. She began working as a dental assistant in 2014 and has been making HDC patients feel welcome, comfortable, and cared for since 2016. Eventually she would like to transition to providing clinical care by going to hygiene school.  

Outside of the office, she enjoys spending time with her family and her cat! She also loves to travel.
