Criminal Defense Attorney Based in
Boulder, Colorado

If you or a loved one has been investigated, contacted, or are even concerned that you are a target, or otherwise involved, in a criminal investigation, arrested, threatened with arrest, or given a card from law enforcement with instructions to call, or a message that law enforcement will be in touch, CALL US IMMEDIATELY. Whether the investigation involves any type of drug, including everything from cannabis to Delta 8 THC to heroin and MDMA, you need and deserve a former judge and diligent criminal defense attorney along with his law firm to protect your rights.

The impact of a potential case may range from asset forfeiture to arrest to interrogation. All must be addressed immediately and NOT by you or anyone else beyond your lawyer. DO NOT discuss what did or did not happen with anyone else. Your communications with your attorney, even during an initial phone conversation, are kept strictly confidential and privileged. Unless you discuss a future crime that you plan on committing, attorneys are duty bound, ethically bound, and required to keep your confidences.

Contact me, Leonard Frieling at (720)320-6201 immediately to move forward. I also represent those facing charges in Larimer, Denver, Broomfield, Jefferson County, Adams County, Gilpin County, Park County, Clear Creek County, Lake County, and Arapahoe County, Colorado. I have handled cases all over the state of Colorado, as well as other states. Remember that the "money meter" is not running until you sign a fee agreement and pay a retainer. Retainers are determined by the firm attorney who will lead your representation.

REACH OUT IMMEDIATELY TO (720)320-6201, voice or text. If I don't answer immediately, you must leave a message with your phone number repeated twice. Calls are returned promptly. This phone call must happen BEFORE any conversations with any law enforcement, no matter how polite and persuasive they may be. Remember that they know their lines, and you don't know yours!
