Lorraine Sirgany
Dental Hygienist
I have enjoyed practicing as a dental hygienist for over 25 years. I obtained my Bachelors in Science in Dental Hygiene from Fairleigh Dickinson University in 1990. My license allows me to deliver local anesthesia as well as the administration of nitrous oxide to my patients as needed. I am an advocate in the education of my patients on the benefits of a healthy mouth. I have happily provided quality dental hygiene here at Dr. Eichler’s office since 2001. I love gardening and traveling in my spare time.

Lisa Blando
Office Manager / Chairside Assistant
I started working with Dr. Eichler as a dental assistant in 1989. My sister was a dental assistant and I thought it seemed interesting. In 1993, I made the transition to Administrator, running the front office. Multi-tasking is my forte! This includes scheduling, financial aspects, insurance matters, and I still dabble in chairside assisting when needed. Outside the office, I enjoy boating and traveling!
