About Leonard
Biography
I am an experienced trial lawyer practicing in Northern New Hampshire, primarily serving Coos, Carrol and Grafton County. I have successfully argued more jury trials than any other defense lawyer in Coos County. I have been representing people in criminal cases for over twenty years.
I am recognized by my peers as possessing exceptional knowledge in the field of DWI. I have served on an editorial board for James Publishing, Inc. and written a chapter on breath testing in a book to be published by Massachusetts Continuing Legal Education, Inc. (MCLE) focusing on New Hampshire DWI defense. I have been a presenter and chair person of New Hampshire defense lawyer trainings sponsored by the New Hampshire Association of Criminal Defense Lawyers Association on Advanced DWI Defense.
I am certified according to the National Highway Traffic Safety Administration (NHTSA) to administer the standardized field sobriety tests (horizontal gaze nystagmus, walk and turn, and one leg stand.) I am also certified to operate, maintain and repair the Intoxilyzer 5000. I have been certified to operate the Intoxilyzer 8000, the SD-5 and Intoximeter FST and taken advanced forensic blood classes. I am a member of the American Academy of Forensic Sciences. I am better trained than the police officer who arrested you. I have the experience to focus on the proper methods to attack the state's case against you and win.
I am available 24 hours a day for emergency consultations.
Harden Law Offices was established in June of 2003. I opened a second office in the summer of 2005 in Littleton to better serve the North Country. In the fall of 2011, I also acquired a Lebanon office. I am willing to meet with clients before or after normal business hours. I take pride in returning calls personally and in handling all of my cases from start to finish.
I have been focusing on criminal defense with a larger firm from southern New Hampshire and managing their office in Lancaster for over 7 years. Prior to my work with the southern firm, I worked in a North Country general practice firm focusing on criminal defense. It was during my time at the general practice firm that I began taking court appointed cases from local courts in northern New Hampshire.
I have been defending cases in northern New Hampshire for over 20years.

Over-charged after verbal agreement.
I believe Len Harden took advantage of me by overcharging for a simple case wherein HE TOLD ME my case would cost around $500 if not much was done. Then, although the case took several months to resolve while courts were stultified by the pandemic, the $500 turned into $1,800 ( the full retainer giv...
Leonard D. Harden's Lawyer Endorsements
"I am very happy to endorse Len Harden as a true expert and attorney in DUI defense. Unfortunately, what many people facing a DUI don’t know is that there are literally hundreds of attorneys in any metro area who will handle their DUI. However, maybe only a handful of these attorneys truly know how to defend these complex scientific cases. If you submitted to a blood test, breath test or even standardized field sobriety tests, then you need an attorney who has years of formal training and experience defending these complex cases. Hiring anyone else is usually a recipe for losing. I have known Len for about seven years, and I can assure you he is one of those few attorneys who has a complete understanding of the science necessary to challenge these cases successfully. If I ever needed to refer someone to the best DUI attorney in New Hampshire, I would only refer them to Len Harden. Christopher H. Cessna Attorney at Law Denver, CO"
"I have known Len Harden for years and I've had the chance to watch him in court first hand. He is an outstanding DWI champion. I refer clients who get arrested for any crime in the North Country to Len Harden without reservation. There is no need to call any one else for DWI defense in the North Country."
"An excellent lawyer who treats clients with patience, care, understanding, and utmost professionalism - an even better person and I wholeheartedly recommend for future services."
"Since I started practicing law I've followed what Len was up to in the North Country. I've watched his trials, attended his seminars, and even studied (read: copied) his pleadings. He is a tireless defender that anyone would be lucky to have."

"I endorse this lawyer. Len Harden is a well known member of the prestigious National College of DUI Defense. He knows the science. That's important because nearly ass DUI defenses require a scientific defense. What you don't know, if that most lawyers who practice DUI defense have little knowledge of the science. You must beware when searching for a truly talented and educated DUI lawyer. Look no further. It's Len Harden."

Attorney Harden represents the best of this country's DWI defense bar. Any motorist would do very well to hire him."
"Talented lawyer."
"Len and I attended Field Sobriety Testing Instructor school together. Len is extremely knowledgeable in DUI/DWI defense. He's had more training in DUI/DWI than most police officers, and knows how to use that training against them. I wholeheartedly endorse Len's work."
"I have known Len Harden for several years and believe that he is one of the elite DWI lawyers in New Hampshire. He works hard for his clients and will fight for them even if the case seems unwinnable. His trial skills are second to none and he is very articulate, intelligent and personable. Without a doubt, I would recommend Len."
"I've known Len through the National College of DUI Defense and through attending the Forensic Science for DUI Lawyers conference in New Orleans this year. Len Harden is a lawyer's lawyer. He is an expert on Standard Field Sobriety Tests and breath testing. I know Len cares about his clients because Len cares about people. It's very rare to find a lawyer represent you and COUNSEL you. Len is the type of lawyer to trust your future with because he is relentless. I'd recommend my family call Len if they ever got arrested in New Hampshire. You'd be lucky to have him accept your case."
"It is with great pride that I endorse Len. He is the type lawyer everyone wants representing them. He is smart, articulate, knows the law—but most of all he believes n his clients and fights for them all the way. I am glad to endorse my friend, colleague and fellow warrior."
