Who is Mark S. Rubinstein?

Mark S. Rubinstein is the founder of the firm and its only practicing attorney. He earned his law degree from the University of Denver College of Law in 1989 and his bachelor’s degree in business management from Western State College in Colorado. He was admitted to the California bar in 1990 and the Colorado bar in 1993, and he has practiced in Colorado ever since.

How does Mark’s background help his clients?

Mark has worked on both sides of the cases he now handles.

He has worked within the Colorado Denver Drug Court, which gives him a court-system view of how drug cases are handled. He has also worked as a defense attorney for large insurance companies, so he knows how insurers evaluate and defend injury claims. Today, he uses that perspective for injured people instead of against them.

Will I work directly with Mark?

Yes. As a sole practitioner, Mark handles every part of every case himself. You will not be handed off to a junior associate.

Mark gives clients his personal cell phone number and makes himself available outside business hours, including nights and weekends. He will also travel to meet clients when needed.

Does Mark speak Spanish?

Yes. Mark speaks Spanish and can communicate with Spanish-speaking clients directly.

Why choose a sole practitioner?

Working with a sole practitioner means one experienced attorney knows your case from start to finish. Because Mark does not have to divide his attention across practice areas he rarely handles, he can focus on criminal defense and personal injury and dedicate his time to representing you well.

His approach is built on a few commitments: being available when you need him, listening carefully to your concerns, researching every legal theory and defense in your case, and working tirelessly to get the best possible result.

What outcomes have Mark’s clients described?

Outcomes that clients have described in their published reviews include:

  • A DUI case resolved as a DWAI plea, with other traffic charges dropped, despite a fairly high BAC
  • A DUI case resolved in a way that let the client keep their license and keep a DUI off their record
  • A speeding stop that became a DUID charge, resolved as a deferred DWAI
  • A sealed dismissal
  • Reduced charges after a serious speeding stop
  • A reduced sentence in a serious felony case

Past results do not guarantee a similar outcome. The outcome of every case depends on its own facts.

Will Mark take my case to trial?

Yes, when that is what your case needs. Mark represents clients from beginning to end, from negotiations to court trials and appeals.

Many cases are resolved through a negotiated plea, a deferred judgment, or a settlement, and that can be the right result for a client. When it is not, Mark is prepared to take the case to court.

What happens after I hire Mark?

In a criminal case, Mark reviews the charges and the evidence, researches every available legal theory and defense, and gives you a clear picture of the strengths and weaknesses of your case. He handles your court appearances and negotiations and keeps you informed about upcoming dates and decisions.

In a personal injury case, Mark investigates what happened, documents your injuries and losses, and deals with the insurance companies so you can focus on healing. He uses his experience defending insurers to anticipate how the other side will evaluate your claim.

How much does it cost to hire Mark?

Your initial consultation is free.

Criminal defense: Depending on the case, Mark works on a flat fee, hourly, or retainer basis.

Personal injury: Cases are handled on a contingency basis, so there is no fee unless Mark recovers money for you.

No. Mark makes himself accessible to clients throughout Colorado and will travel to meet you when needed.

How quickly should I contact a lawyer?

As soon as possible.

In a DUI or criminal case, early decisions can affect both your court case and your driver’s license. In an injury case, evidence is easiest to gather right away, and insurers often start evaluating the claim quickly.

Do not assume you have plenty of time. Mark can tell you what applies to your situation.

For a criminal or DUI case

  • Your ticket, summons, or charging paperwork

  • Any paperwork about your driver’s license
  • Any bond or release conditions
