Lori Ostir

Lori received her degree in Dental Hygiene from Broome Community College and knew from the first day she started her career that it would be both satisfying and rewarding.  Through oral hygiene education, Lori will provide you with the confidence to keep your teeth healthy and your smile looking it's best.  Lori aspires to treat each person based on their individual needs and never compromises quality of care.  Staying on the cutting edge of dentistry is important to her, and she routinely adds to her expertise through continuing education.  Her goal is to provide a comfortable, positive dental experience, and she is certified in administering local anesthetic.  Her experience provides reassurance that your oral health is in good hands.  Lori would like to add, "I am pleased to work at an office that upholds the highest ethical and moral standards, as well as being part of a team that shares a passion for optimum dental care."

Lori Mizenko

Lori received her Dental Hygiene degree from Luzerne County Community College.  Her goal is to inspire all of her patients to keep their teeth for their lifetime.  She achieves this through chair side hands on motivation in methods of homecare.  It is her belief that dental health takes two, the patient's willingness to do their personal best and a team of dental professionals to help get them there.  She continues to further her education with schooling in the newest and best techniques dentistry has to offer.  Endless Smiles supports her in staying on top of her profession in skill and knowledge.  Lori wants all of her patients to feel special and comfortable.  Local anesthesia is one method Lori is certified to provide for those that are sensitive.  It is her goal that all patients feel "cared for" and not just taken care of.
