About Jason

Learn Jason’s areas of practice.

Mr. Márquez has practiced law since 2008, almost exclusively in the fields of family law and criminal defense.

After practicing law for nearly ten years at a firm where he was also an owner for several years, he started Márquez Law to redirect his focus on practicing law and not the bottom line.

Mr. Márquez brings a unique set of skills to Colorado family law with an extensive background in the corporate world where he provided operational, technical, management, finance, and legal support to several corporations. His background makes him perfectly suited to work with challenging issues including:

High Conflict

Complex Financials/High Stakes

Domestic Violence

Substance Abuse

Education:  

 

Mr. Márquez acquired a BA from Westmont College where he double majored in Economics & Business and Physics. He went on to acquire an MBA from the University of Colorado at Denver with an emphasis in change management. He acquired his Juris Doctorate from the Denver University Sturm College of Law in 2007 where he was awarded the Outstanding Student Attorney Award and Student Leadership Award.

Strategies:


Mr. Márquez is a Colorado native and was raised in a single family home. His personal appreciation for the plight of single parents in family law cases drives him to advocate for clients no matter what, remaining steadfast and conscientious of the issues in each case. Throughout the entire case, Mr. Márquez is efficient and mindful of his clients’ goals and resources.

Mr. Márquez is analytical, organized and compassionate. He is devoted to diversity, family values and most of all, meticulous preparation of his cases at each stage. Preparation requires a careful and empathetic listener with outstanding interpersonal skill at which Mr. Márquez excels.

With tactful persistence, Mr. Márquez aggressively negotiates agreements, where appropriate, improving the situation of his clients and their families. When aggressive negotiation fails, Mr. Márquez is a confident and successful litigator. Mr. Márquez loves the courtroom but recognizes that clients may fare better with a negotiated outcome that they control.

Mr. Márquez believes that the key to success in family law matters is organization, preparation, and intimate familiarity with each case. Often, this includes tough love, management of client expectations, empathy, and a deep understanding of the law.

Mr. Márquez began as an associate and through hard work and dedication, was promoted to senior associate not too long after in his career. He went on to contribute significantly to the firm’s mentor program and pioneered the use of iPads in the Courtroom. His office is almost entirely paperless. Mr. Márquez became a senior partner in early 2014 and is fully committed to helping his clients start over. Even when a client does not achieve each and every goal, Mr. Márquez is still recognized for his diligence and efforts such that client satisfaction, retention and referrals are exceedingly common.

Community Involvement:


Mr. Márquez is currently the Vice President of the board of directors for Law School…Yes We Can!, which is a pipeline program for college bound students from underrepresented communities who want to be lawyers in an otherwise non-diverse community.

​Mr. Márquez has volunteered for Metro Volunteer Lawyers where he assisted pro se litigants in predominantly post-decree matters.

Mr. Márquez has been appointed as a guardian ad litem for the Rocky Mountain Children’s Law Center.

Mr. Márquez also served on the board of the Colorado Criminal Defense Institute which is responsible for educating lawyers and championing changes in the law to protect Colorado’s citizens.

Mr. Márquez was also on the finance committee for the Colorado Criminal Defense Bar.

Mr. Márquez is a member of the Colorado Bar Association, the Denver Bar Association, and the Colorado Hispanic Bar Association.

​Mr. Márquez is an active member of the Justice Sotomayor Inn of Court.

Highly Recommended
I knew Jason was the attorney for me when I first consulted with him. Dealing with a very high conflict situation, a business, and several properties, I wasn't sure how to even begin, but Jason was confident and had experience with situations like mine. His skills in the courtroom, how prepared he was, attention to detail, and his wonderful team got me a better outcome than I could have imagined.

The Only Family Court Lawyer I Trust
My divorce has been a mess from day one. I have made the acquaintance of several lawyers since the beginning of my divorce and I have only met one who was willing to take the time and had the requisite patience to deal with not only the family courts but a less than agreeable ex. Jason is often the smartest guy in the room and you need that when you go to family court. Long story short, I wish I had met Jason from the beginning. I also recommend Jason to all my clients going through divorce.

Helpful Guidance
I was legally represented by Jason for my divorce case which involved domestic violence. I was confused and didn’t know where to go or what to do when it came to going about the divorce. Jason’s previous experience in criminal justice really helped my case because he seemed to know everything about what the court would ask and think about my particular case. He guided me through getting the evidence I needed to show the abuse and also helped me get a restraining order on my ex-husband. Throughout the whole case I felt like I was in good hands. Now I’m able to move onto a new chapter of my life thanks to the legal services of Jason Marquez.

Quick Easy Divorce - Thanks!
This law firm was really great in helping me through a quick and easy divorce. Even though my ex-husband and I didn’t have any children we struggled financially after we started a business together and it failed. The downfall of our business took a toll on our relationship so we decided it was best to start over again and part our separate ways. Johnson Marquez assisted us in sorting out our financial issues and helped us come to a resolution. My ex-husband and I still remain friends and thank Johnson Marquez for their excellent service.

Great Child Custody Consultations Help & Services
About two years ago, my wife and I of 10 years decided to call it quits. While we were mostly on good terms, we thought it best to seek out lawyers to help us go through the process smoothly. All I can say is, “Thank God I found Johnson Marquez Online.” First of all, their website is very informational, and I was able to do some much needed homework before I reached out to them. Plus, by the time I actually got around to hiring a lawyer I was at my wits end dealing with my wife’s attorney and the custody issues surrounding our children—both 3 and 4 at the time. Having to talk about having a custody agreement with my wife regarding my kids was the most difficult thing to dos, and I am glad I had Johnson Marquez to help consult me. While I have heard this process is extensive, they made it easy and my now ex-wife and are able to see our children equally.

Honest and Caring Guidence
I was afraid to get a divorce at first even though I had to leave my husband. Jason talked with me about my options, and was very clear about the bumpy road ahead. I decided it was time to file for divorce after my initial consultation, I’m grateful for Jason’s guidance and his honesty through the whole process. He made me feel confident about proceeding and in the end I couldn’t have dreamed of a better result. Thank you so much!

Professional, Personal and Legal Advice was outstanding
I would like to take this time to thank Jason for his professional services, personal advice and outstanding legal advice at a dark time in my life when I needed it the most. Jason got me through my divorce and his experience helped keep my marriage from falling apart. I had no doubt in my mind; during any part of the case that Jason would not obtain the results I wanted. I also want to thank Jason for allowing me to have a bright future and a life filled with no regrets.

His hard work and guidance got me through my divorce
Jason represented me when I sought custody for my teen. For fourteen years, her mother had physical custody and was her primary caretaker during that period. Since her mother and I weren’t married, I could tell the battle would be tough. After dealing with several attorneys in the past, I knew that Jason knew what he was doing as his performance in navigating the legal system was unprecedented. He was upfront with me at all times and was a true professional in every sense of the word. I am convinced that my success in court was due to his meticulous attention to detail and hard work. I highly recommend him.

Very happy with the outcome
I am very happy with the outcome of my divorce case. Jason Marquez explained what needed to be done, kept me informed during the process, and guided me every step of the way so I was never surprised by anything. He's confident, focused, and I've never had any doubt about his ability. I didn't get everything that I wanted in my divorce, but I was informed of the possibility beforehand. Even still, I knew that it wasn't a result of his knowledge or attentiveness. I have no regrets about my choice in attorney or the outcome. I'll refer him to anyone who may need his help in the future.

Satisfied Former Client
As a former client, I would recommend attorney Marquez to anyone seeking a family law attorney. Hiring him paid off in the end for my divorce case. The attorney works around the clock for his clients and creates a strategy that allows his client to seek the most favorable results possible. Every case is different, but I assure you that attorney Marquez will devote his time in understanding your exact circumstance and finding the most appropriate way to handle it.

Beware bait and switch then overbill and sue client...
I hired an associate attorney at Johnson Marquez Legal group. The attorney that was assigned to my case left the firm shortly thereafter and I was assigned to new attorney. The firm failed to disclose/ notify me of the new attorneys rate and billed me a much higher rate for the new attorney I was assigned to. By not notifying me of the new attorneys rate they breached there own fee agreement. Additionally I was billed for time and tasks that were redundant, billed for tasks that never happened, and for others that should not have happened. Now Jason Marquez has filed a lien and obtained judgment against me. Mr Marquez refuses to participate in legal fee arbitration through the Colorado Bar Association. Additionally Mr Marquez sent the lien and judgment paper work to me at an address I do not reside at. In a Reply to my response to his motion to reduce lien to judgment, there are several things this attorney has asserted that are outright untruths. If you want to be SUED by an attorney at the firm you hire to represent you and help you then hire this guy, otherwise stay away, far far away.

Response from Jason Marquez March 21, 2017
Thank you for your comment. Because of the attorney client privilege, I am not able to specifically discuss your case in this public forum. However, I understand your concerns and can confirm that I pursued every reasonable mechanism by which to resolve the alleged dispute about the fees that were billed in your case. Unfortunately, we were not able to reach an agreement. The firm complied with all terms and conditions in your Fee Agreement. I remain committed to finding a solution to address payment. However, I cannot do that in this setting.

Bait and switch
I thought I hired Mr Johnson based on his reputation and he introduces Mr Marquez as someone who will help with the grunt work to keep costs down. That is the last I ever saw of Mr Johnson even though I Repeatedly asked for him. I got saddled with Marquez who was only concerned about one thing....money! Sloppy, weak in court, forgetful of very important details, enormous amount of billed hours for simple tasks, etc. If he would have only been half the bull dog in court that he was when collecting his inflated bills we would have done much better. I recently discovered the firm is in bankruptcy which is clearly why the are all about the money.

Response from Jason Marquez April 14, 2017
Thank you for your comment. Because of the attorney client privilege, I am not able to specifically discuss your case in this public forum. However, I can confirm that we accomplished nearly every single goal you had when you retained the firm. You were a client for nearly 7 years and received assoicate rates for partner level work. In all, you received tens of thousands of dollars in discounts and did not raise any concerns in nearly 7 years. The firm is most certainly not in bankruptcy. It is unfortunate that this alelgation, much like this comment, is not grounded in fact. I woudl be more than happy to discuss your concerns in a more appropriate forum.
