Kathy Brown, Front Desk Coordinator

Hi, my name is Kathy.  I have worked here at LaFayette Dental for 25+ years.  I started as an assistant and worked my way up to the front desk.  I am from South Onondaga and graduated from Onondaga Central Schools.  I am married with four children and two grandchildren.  We live in the Navarino/Otisco area.  I enjoy gardening, camping, boating, and spending time with my family.

Erika Deyneka, Receptionist/Dental Assistant

I grew up in the North Syracuse area, where I graduated from CNS High School.  I worked for six years as an orthodontic assistant in Syracuse before joining LaFayette Dental in 2016.  I married my Jr. High School sweetheart and have two daughters, 9 and 6 years old.  We live in the Liverpool area now.  I have a love for animals and my house is full of them.  We have a Siberian Husky, three cats, and a fish.  They all make every day a little more interesting!  In my free time I love to camp, boat, and hunt with my father.  My favorite thing to do is travel.

Lisa Hart, Registered Dental Hygienist

I joined LaFayette Dental Associates in February 2014.  I am originally from this area, graduating from Fabius-Pompey High School and Onondaga Community College.  I have been a dental hygienist for 23 years.


My husband of 20 years is also from this area.  We have one son, who is currently attending Clarkson University. I love the outdoors, and have a passion for dogs and horses.

Stephen P. Sheffield, DDS

I received my bachelor's degree in Exercise Science from Brigham Young University in 2004, where I graduated Magna Cum Laude.  I then returned to my home state of Minnesota to attend dental school at the University of Minnesota, graduating in 2008.  After dental school, my family and I moved to Syracuse to complete a one-year residency in General Dentistry at SUNY Upstate Medical University.  During my residency, I received more extensive training in Oral Surgery, Endodontics (root canals), and Periodontics (treating gum disease).


After working in a group dental practice in the Binghamton area, my family and I moved back to the Syracuse area, taking over LaFayette Dental Associates in December 2011.


My wife and I live in Pompey with our five children.  We all enjoy downhill skiing, waterskiing, hiking, camping, and other outdoor activities.

​Katie Spencer, Certified Dental Assistant


Hello, I grew up in the Tipperary Hill area of Syracuse. I now live in Apulia Station with my husband and our three children. In 2004 I graduated from George W. Fowler and started waitressing at China Pavilion Restaurant. I found a love of dentistry and graduated the dental assistant program at OCM Boces in 2010. After becoming a dental assistant I worked in an orthodontic office for close to 6 years. I joined the team here at Lafayette dental associates in April of 2017. I have been blessed to be able to work with this great team and look forward to many more years here. My favorite thing to do on my free time is go to concerts.
