Greenwood Village Child Support Lawyer


I am now in my 30th year practicing law in the wonderful State of Colorado. I have spent all those years in our courtrooms, traveling across the state to fight for clients in family law (divorce and postdivorce), personal injury, and minor criminal defense matters. While courtroom work is something I love, working toward just resolutions in cases always comes first...

I am now in my 30th year practicing law in the wonderful State of Colorado. I have spent all those years in our courtrooms, traveling across the state to fight for clients in family law (divorce and postdivorce), personal injury, and minor criminal defense matters. While courtroom work is something I love, working toward just resolutions in cases always comes first. At Ammarell Deasy, we pride ourselves in our ability to fashion resolutions that give our clients control of outcomes - outside of courtrooms. As for me, there is very little that I have not encountered in the legal world, so if you need help dealing with anything, feel free to track me down to see if I can either give you the full service of our firm or steer you in the right direction.

When seeking legal counsel, "fit" matters. You need to make sure you have comfort and security working with your lawyer. I know that when people need attorneys, the circumstances usually aren't the best. We work hard to meet your needs and give you timely guidance in challenging times. While we can never guarantee you a result, we can promise to do everything we can to deliver the outcome you seek!

We have dealt with everything from multi-million-dollar estates to horribly abusive relationships in the family law arena. What we value even more than the "work," however, are the relationships we build with clients. When Laura and I started Ammarell Deasy, we decided that our firm would be different from the places we had left behind - focused on commitments to customer service and superior representation. As the proud son of a retired Denver Police Officer, I learned the value of service at a very young age. I also learned through various legal mentors over the years that effort never takes a day off. Put a service motive and effort together and you have a family law attorney ready to help no matter how difficult the circumstances.

When not in the office, I spend a great deal of time teaching. I travel around the nation teaching advocates how to stand up before judges and juries and "do it" the right way for the National Institute for Trial Advocacy (NITA). I have been selected to serve as faculty for the American Bar Association's Family Law Trial Advocacy Institute in Boulder, Colorado. I have taught at the Colorado District Attorney's Council, for the Colorado Defense Lawyers' Association, the Denver City Attorney's Office, the Colorado County Attorneys Association and for the Colorado Bar Association on multiple occasions. I think I have lectured on every aspect of courtroom work over the last ten years for both state and federal litigators. I have worked as an adjunct law professor at the University of Denver Sturm College of Law for two decades and I am proud to see many of my former law students working hard in Colorado's courtrooms and law firms, with a few having taken the bench. I am also a past President of the Douglas/Elbert Bar Association and a past Regional Vice-President for the Colorado Bar Association.

After all these years, I am humbled to know that my colleagues think I bring something positive to the profession, as the links below show. I can't help but remember what my mom and dad told me many years ago: "You won't get any place in this world unless the people you work with want you around."

These days, if I am not doing something in the legal world, I am probably cycling down some roadway or path in Colorado or trying to lift weights, wondering why I'm not as strong as I was at 25 years old!! With two degrees from the University of Colorado, you can imagine how much I love my Buffaloes on fall Saturdays. Of course, that love is matched only by my passion for the Broncos on Sundays!

And of course, ultimately, the balance I try to keep in my life is tethered by my wife. I told her ten years ago that when the angels ask what I loved most about life, the answer will be "you." That never changes.

Many attorneys have discovered reputations matter in our world of social media and on-line reviews.

When a pair of judges were asked to evaluate co-founding partner Daniel Deasy in the areas of legal knowledge, analytical capabilities, judgment, communication ability and legal experience, they offered the following:

Tremendous litigator - able to quickly analyze a case and prepare persuasive arguments. Knows the law extremely well. Has a rare gift of being able to connect with jurors and witnesses in a friendly, nonintimidating way to put them at ease. Incredibly hard worker- will go the extra mile (or ten) to adequately prepare and present his case. Has earned the unqualified trust, respect and admiration of this judicial officer. Highest possible recommendation.

Outstanding trial attorney. Ethics beyond reproach. One of the best litigators I've ever seen - persuasive, reasonable and knowledgeable. Would place the highest confidence in him and his abilities. Tremendous grasp of the rules of evidence and procedure. Highest recommendation.

Attorneys in Colorado offer the following comments about Mr. Deasy:

Grade "A", First Class, Outstanding Lawyer.

Dan is an excellent trial attorney.

Dan is an excellent lawyer who cares deeply about his clients. I have tried cases against him and hold him in the highest regard.

Daniel Deasy has quickly distinguished himself as one of the top Family Law practitioners in the State. I have referred clients to Dan and he has taken great care of them - enhancing his reputation in the process while protecting mine!

While it's nice to be recognized by colleagues and judges, clients have kind comments about Daniel Deasy as well: The words, kindness and guidance I have received from this practice, have been life changing for me. Everyone that is a part of this team, from the front desk all the way to the attorneys, have helped me regain my sanity and strength, something, that I had been missing for so long. Everyone I've interacted with at this office has been more than kind to me. There have been times, when I was a complete and utter mess or needed a lifeline, and with every interaction with Dan, or the wonderful people behind the scenes, they took their time to just help or listen to me. The moment I landed at the front steps of their office, the chaos began to finally stop and started fading away. I could finally see that there was a light at the end of the tunnel and what my path forward would be. To anyone wearing the shoes I was when I arrived at their door, there is help, and the office of Ammarell Deasy is it. I truly can't say enough amazing things about everyone at this practice! Thank you again for everything!

Finding words to express my gratitude to the Ammarell Deasy Law Office is hard because how do I put into words what family means to me? Dan and Shawn took my very difficult case by the horns and rode it like a bull ride at the National Rodeo Championships. They fought hard for me in pursuit of my greatest assets in three precious children. They surrounded me every step of the way and pulled and pushed me through a nightmare I never expected to experience. If you are traversing the walk through the Hell that a conflicted divorce can create, Ammarell Deasy will guide you, protect you and advocate for you relentlessly with a safety first and no fear mindset until you make it out on the other side. I don't promise much but I promise you that you will be in the arms of valiant warriors fiercely committed to ensuring the right outcome for you and your family. And family is who they are and always will be to me. This law firm redefined gratitude for me. Thank you!

Mr Dan Deasy represented me through my very technical divorce and did an amazing job. I respect him very much as a lawyer and a friend. He ALWAYS had my family's best interest in mind. I highly recommend him and his firm to anyone seeking representation. I love you Dan! Thank you!

I began working with Dan more than six years ago in a very, very contentious custody battle. I have to say that, without a doubt, he is the finest courtroom attorney I have ever seen - and I have worked with several. Watching him fight for my girls was unbelievable. For anyone who asks about my experience and needs help, I just say, "you have to hire Dan Deasy." Dan just gets it. I can't imagine ever looking elsewhere for help in a custody case.

My entire experience with Mr. Deasy and his office has been amazing. Since my consultation I have felt completely confident that I could not have hired a better attorney. I was continually kept informed of everything involving my case, was prepared for my trial exceptionally well and very satisfied with the results. Mr. Deasy is an amazing attorney that is very knowledgeable and his courtroom demeanor is unsurpassed. He put me at ease with the situation even in the most stressful moments. His staff and fellow attorneys were exceptional as well, every communication I have had with them was handled professionally and promptly.

I have worked with Dan since 2009 and he is, simply put, a miracle worker. He understands the needs of his clients and makes sure that everything makes sense along the way. There is nothing he is not prepared to handle in the courtroom. Having looked back at some of the reviews on another website, judges use the words "excellent" and "outstanding" in describing his courtroom skills - they are more than right. I give Dan the highest recommendation possible.

How do I choose a lawyer?

Consider the following:

Comfort Level
- Are you comfortable telling the lawyer personal information? Does the lawyer seem interested in solving your problem?

- How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?

- How are the lawyer's fees structured - hourly or flat fee? Can the lawyer estimate the cost of your case?

- Is the lawyer's office conveniently located?

Not sure what questions to ask a lawyer?

Here are a few to get you started:

  • How long have you been in practice?
  • How many cases like mine have you handled?
  • How often do you settle cases out of court?
  • What are your fees and costs?
  • What are the next steps?

Want to check lawyer discipline?

It is always a good idea to research your lawyer prior to hiring. Every state has a disciplinary organization that monitors attorneys, their licenses, and consumer complaints. By researching lawyer discipline you can:

  • Ensure the attorney is currently licensed to practice in your state
  • Gain an understanding of his or her historical disciplinary record, if any.
  • Determine the seriousness of complaints/issues which could range from late bar fees to more serious issues requiring disciplinary action.
