Michelle graduated from Springfield Technical Community College where she was a member of the Phi Theta Kappa Honor Society. She lives with husband, Jonathan, their daughter, Natalie and their son, Andrew. Michelle is a reality TV junky who loves crafting, Zumba, trivia, and walking in her spare time.



Lydia: Licensed Dental Assistant

Lydia is from Greenfield, where she lived until moving to Fort Drum NY, while her husband was deployed to Iraq. She pursued a career knowing she wanted to help people, and worked as a Medical Assistant for a dermatology office. She was able to transfer offices when she and her family relocated back to Western Mass. She grew a passion for providing patient care, eventually transitioning into the dental field.

She and her husband currently reside in Erving, MA, with their chihuahua and cat. She loves music, dancing, ice cream and puppy kisses.

“The most rewarding part of my job at Strong and Healthy Smiles is seeing a patient with a renewed confident smile after treatment.”



Neph: Licensed Dental Assistant

Neph is a brand new addition to our team! She was raised in Pennsylvania, and happy to have recently moved back to Western Mass: she feels at home within this community like no other. Since 2008, when she had a digestive health scare of her own, she was inspired to study holistic health. Quickly she learned that all parts of the body are intrinsically connected and her immersive journey led her to joining our team to study as a dental assistant through the lense of a holistic healer. She loves to dance, sing and constantly learn. She feels exploring her creative sides are ways she can stay happy, healthy and ultimately stay positive and keep smiling.
