Your Chiropractor

David McGonagle is a Pennsylvania native, hailing from Delaware County. He attended Albright College in Reading, Pa where he earned a bachelors degree in biology. After working as a technician in vaccine and genetics laboratories, Dr. Dave found his calling in chiropractic.

Dr. Dave is an alumnus of Life College (now Life University), School of Chiropractic. He graduated in March of 1996 with honors (cum laude) with a Doctor of Chiropractic degree. Soon after, Dr. Dave moved to Hellertown and worked for Myers Chiropractic for a few months before striking out on his own. He created Hellertown Family Chiropractic in October of that same year, and opened an office in Hellertown. Dr. Dave bought a home on Main Street in 1999, and then ran a home-office for several years.


In the Year 2000, Dr. Dave married Hellertown native Mary (Lewis) McGonagle and started a family soon after. Although the family has moved out of the second floor apartment, they are only minutes away and are in the office frequently getting their spines checked (and having family fun).

Dr. Dave can be found throughout the community giving presentations on chiropractic, health and life to small organizations and large corporations alike. You may see him speaking with folks about chiropractic at the Hellertown Community Day, the Saucon Valley Farmer’s Market and just about anywhere he is given the chance to let people know the truth about chiropractic. You may even find him at a local hospital once in a while checking the spine of a practice members new born baby!

The Office

Hellertown Family Chiropractic is located at 221 Main Street (Route 412), Hellertown. The office resides on the main floor of an old colonial home built in the 1860’s. There is off-street parking in the rear of the building with the back door used as the main entrance. When you enter the office, don’t be alarmed that there is no front desk, no reception area, and no receptionist. We have found this to make the office more cost effective and time efficient. The comfortable waiting room is the holding room where Dr. Dave will greet you when he is done adjusting the person on the chiropractic table.

The office has a wood-burning stove to keep it cozy in the winter, and central air to keep it cool in the summer. You may notice there is only one room that has a door (aside from the restroom). This is because we have an open-concept to the office. The one room is for private conversations, for consultations and for moms who want to nurse their babies in private. The open-concept is because chiropractic should never be kept a secret.

You may notice photo albums around the office. They have pictures of kids and families that have received chiropractic care over the years. When you become a practice member, if you permit it, we would like to put your family picture on our WALL OF FAME. You should check it out. You may find some faces you know.
