Background

Two decades in Central PA courtrooms.

Sean P. Quinlan has spent more than 25 years representing Pennsylvanians at the worst moment of their year — a DUI arrest on the way home, a citation that threatens a commercial license, a criminal charge that follows a background check for the next decade.

He is a graduate of Bloomsburg University and Widener University School of Law, admitted in Pennsylvania under bar number 86858, and an active member of the National College for DUI Defense, the Pennsylvania Bar Association, and the Cumberland and Dauphin County Bar Associations.

From the Camp Hill office he appears in magisterial district courts, Courts of Common Pleas, and PennDOT hearings across Adams, Cumberland, Dauphin, Franklin, Lancaster, Perry, and York counties. Knowing how a specific judge, district attorney, and ARD office actually handle a file is often worth more than anything written in a brochure.

Every case is handled by Attorney Quinlan personally — the attorney you speak with on the first call is the attorney who stands beside you in court.

FAQ

Questions about working with Attorney Quinlan

  • Sean P. Quinlan, Esq. is a Pennsylvania defense attorney based in Camp Hill (PA Bar #86858) with more than 25 years of experience handling DUI, criminal, and traffic matters in Central Pennsylvania. He is a graduate of Bloomsburg University and Widener University School of Law and a member of the National College for DUI Defense.

  • DUI and refusal cases under 75 Pa.C.S. § 3802, ARD admission and expungement, misdemeanor and felony criminal charges (drug, assault, theft, firearms, domestic-violence-related charges), traffic citations and CDL matters, license suspension and PennDOT hearings, and expungement and governor's pardon applications.

  • Magisterial district courts, Courts of Common Pleas, and PennDOT hearings across Adams, Cumberland, Dauphin, Franklin, Lancaster, Perry, and York counties.

  • Yes. Clients speak with Attorney Quinlan from the first call through resolution. Cases are not handed off to paralegals or junior associates.

  • Call (717) 724-7503 or submit the consultation form on this page. The office is at 3425 Simpson Ferry Rd, Suite 100, Camp Hill, PA 17011, open Monday through Friday 8:30am to 5:30pm, with after-hours calls returned. Initial consultations are free and confidential, and recent arrests or imminent hearings are prioritized.

  • Fees depend on the charge, the county, and whether the case resolves at the preliminary hearing, through a diversionary program like ARD, or at trial. Attorney Quinlan quotes a flat fee for most DUI, traffic, and misdemeanor matters after the free consultation, so you know the cost before you hire. There is no charge for the initial consultation.

  • Write down everything you remember about the stop while it is fresh, preserve any paperwork you were given, and do not discuss the case with anyone other than a lawyer. Watch for a preliminary hearing notice and any PennDOT correspondence, and call before you make statements or accept an offer. Blood and breath results and the legality of the stop are often contestable.

  • A summary traffic citation is often resolved in one magisterial district court appearance within a few weeks. A DUI or misdemeanor case typically runs three to nine months from the preliminary hearing through disposition, depending on the county. ARD admission timelines vary by district attorney's office, and license consequences can begin separately through PennDOT.

  • Sometimes not. For many summary traffic matters, counsel can appear on your behalf. DUI and criminal cases usually require your presence at key proceedings, though hearings can often be scheduled to limit the number of trips to Pennsylvania. Out-of-state drivers cited in Pennsylvania also face home-state license consequences, which is reviewed as part of the case.

  • Not before someone reviews the file. A guilty plea to a DUI, a serious traffic offense, or a theft charge carries consequences that outlast the fine — points, suspension, ignition interlock, insurance, employment and CDL exposure, and a record that shows on background checks. Many cases have available defenses, reduction paths, or diversionary options that are lost once a plea is entered.

  • Yes. Communications made to seek legal advice are protected regardless of whether you ultimately hire the firm, and the consultation is free with no obligation.

Service Area

Where Attorney Quinlan practices.

Harrisburg, Camp Hill, Mechanicsburg, and the surrounding Central PA counties — including which court hears your case.

  • Yes. Harrisburg charges are heard in the Dauphin County magisterial district courts and, for misdemeanors and felonies, at the Dauphin County Court of Common Pleas at 101 Market Street in Harrisburg. Attorney Quinlan appears there regularly for DUI, drug, assault, and traffic matters, and the Camp Hill office is roughly ten minutes across the river.

  • Yes — the office is in Camp Hill at 3425 Simpson Ferry Rd, Suite 100. Camp Hill citations and arrests are filed in Cumberland County, with summary and preliminary matters in the local magisterial district court and higher charges at the Cumberland County Courthouse in Carlisle.

  • Mechanicsburg is also Cumberland County. Summary traffic citations and preliminary hearings are handled in the Mechanicsburg-area magisterial district court, and DUI or criminal cases move to the Court of Common Pleas in Carlisle, where Cumberland County's ARD applications are processed.

  • Carlisle, Shippensburg, Hershey, Middletown, York, Hanover, Gettysburg, Lancaster, Lemoyne, New Cumberland, Enola, Dillsburg, and the surrounding boroughs and townships. If a case sits outside that footprint, Attorney Quinlan will say so on the first call rather than take it.

  • Adams, Cumberland, Dauphin, Franklin, Lancaster, Perry, and York counties — magisterial district courts, Courts of Common Pleas, and PennDOT license hearings. Local procedure and ARD policy differ by county, which is why the consultation starts with where the case was filed.

  • Yes. Each district attorney's office sets its own ARD eligibility and diversion policy, and each judicial district has its own scheduling practices and preliminary hearing customs. A Dauphin County DUI and a Cumberland County DUI with identical facts can follow different paths, so the county is one of the first things reviewed.

  • Yes. Many out-of-state and out-of-area drivers are cited on I-81, I-83, the Pennsylvania Turnpike, or Route 15. For most summary traffic citations counsel can appear without you; DUI and criminal cases usually require your presence at key hearings, which can often be grouped to limit trips.
