Office Manager

Hello, my name is Patti Grabowski.  I’ve been part of the team since June 2004 as the Office Manager/Front Desk Receptionist.  I enjoy getting to know our patients and their families.  My husband, Dave, and I have two grown children and a granddaughter.  We enjoy being outdoors with our three Shelties, going for walks and spending time with our granddaughter Ruby.  In my spare time, I enjoy cooking, working out and traveling back home to visit family in the Adirondacks.

Hi, my name is Cindy Smith.  I began working for Dr. LaPonzina in 2001 as a Front Desk Receptionist. I enjoy our patients and their parents, getting to know them and seeing them through their ongoing treatment. My joy outside of work is spending time with my ever-growing family.  I also enjoy working out and walks on the Ma & Pa Trail.


Financial/Insurance Coordinator

Hi, my name is Kathy Phillips. I have been with Dr. Joe’s team since 2003. I work in the financial office and take care of insurance and billing.  I also fill in for the ladies at the front desk when needed. I am blessed to work with such a wonderful group of people!  I live in Harford County with my husband Frank and our two grown children.  When I am not working, I enjoy spending time with my family, watching the Orioles and Ravens, reading and vacationing at the beach.


Financial/Insurance Coordinator

Hi, I’m Carolyn Mitchum, and I am part of Dr. Joe’s team.  I attended the Medix School in Towson many years ago and began working for Dr. Joe as a Clinical Assistant.  I worked at the office for just over two years, then left to be an “at-home” mom for a while.  I came back in December 2002 and have worked in the financial office since then doing insurance claims, financial contracts and some billing. I am married and have two grown sons, Sean and Kyle.  I enjoy spending time with family and friends, watching Orioles games, and going to shows and concerts.


Certified Orthodontic Clinician

Hello, my name is  Laurie and I am one of Dr. Joe's clinical assistants.  I began my dental career in 1992 after completing the dental assisting program and becoming X-ray certified at the Medix School in Towson.  After working for a general dentist in Bel Air for eight years, I joined Dr. LaPonzina’s practice in January 2000.  I then went on to become orthodontic certified at Essex Community College. I really enjoy working with the patients and seeing their smiles transform as they go through treatment.  It is very rewarding to me! Dr. Joe is an excellent orthodontist and a wonderful boss.  I couldn’t ask for a better group of people to work with.  We are truly like family. In my spare time, I enjoy spending time with family and friends, traveling, riding with my husband on his motorcycle, and watching the wildlife in our backyard oasis.

Hi, and welcome to our practice.  My name is Lisa.  I have been part of our team as an Orthodontic Clinician for over a decade now (since 2004), and I’m radiation certified.  Being able to watch the amazing transformations here at Dr. Joe’s is completely rewarding.  In my spare time, I enjoy being outdoors and spending time with loved ones.  One last thing… the confidence a beautiful smile gives is unmistakable, and I am so fortunate to be part of a team that provides this!


Certified Orthodontic Clinician

Hi, my name is Jan. I am one of Dr. Joe’s Certified Orthodontic Clinicians.  I’m radiation certified, and I also help with office duties.  I began my dental journey at Medix School in Towson.   After graduating, I worked for a group assisting in general, pediatric and periodontics for a few years.  I was blessed to join this family in June 2006, and it has been the best decision all around.  It is very rewarding to watch the transformations of our patients (kids and adults) and to be a part of a team that is like family. In September 2007, I married my husband, Tim, and we have two growing boys.   As a family, we enjoy spending as much time as possible outdoors, going to the beach and watching the Ravens play!
