Attorney Ryan Callahan

Attorney Profile

Ryan Callahan

I represent people facing criminal accusations and investigations. My approach is grounded in preparation, clear communication, and respect for the personal consequences of a criminal case.

Every matter begins with the facts: what happened, what the government can prove, what evidence must be preserved, and what outcome matters most to the client.

Focused Criminal Defense

Practice Areas

Charges may be similar on paper, but the defense depends on the stop, search, witnesses, testing, recordings, and the client’s priorities.

DUI / OUI Defense

Review the stop, field testing, chemical testing, and license consequences.

Clerk’s Hearings

Prepare a defense before criminal charges are filed.

Drug Offenses & Possession

Examine the search, possession theory, laboratory proof, and alleged intent.

Firearm Offenses

Examine possession, licensing, the police encounter, and forensic evidence.

Domestic Violence & Violent Offenses

Address self-defense, witness credibility, recordings, injuries, and context.

Juvenile Law

Protect a young person’s rights while keeping the focus on their future.

Questions After an Arrest

Protect your rights before you try to explain

It is natural to want to clear things up immediately. But statements, consent to searches, social posts, and contact with witnesses can have consequences that are difficult to undo.
