About Mayra

Learn Mayra’s areas of practice.


I started my first law practice with a partner shortly after graduating from Saint Louis University Law School in 2010.  When I started the firm, I realized that there were many law firms to serve clients who could afford to pay a thousand dollars per month or more for their matter and that legal services and charitable organizations are able to help those living under the poverty line, but there was a great unmet  need for legal services on a payment/installment plan basis.  I have made it my mission to meet this need and help ordinary people.


I focus my practice on divorce, child custody, and support.  I also handle criminal cases.  At Flesner Wentzel, we have attorneys who focus in many practice areas so that we can give holistic and practical legal services.  If a client is being prosecuted for not paying their child support, they often need to have the amount of the support modified by a family law attorney to an amount they can afford.  If a client lives in an unsafe or uninhabitable apartment, they may be vistited by children's division regarding the conditions their children are living in. My goal is not just to get clients through the case they are dealing with now, but to help them make changes to avoid or, at least prepare for, the next case.

Honest and Easy to Communicate With
Erika and Mayra have been helping with my custody case. My ex repeatedly violates the custody order, but the folks at Flesner Wentzel are quick to answer emails and offer solutions. My previous attorney was great in the courtroom, but he often took weeks to respond to calls and messages. I was looking for an attorney who responds faster than that, and I found that in this firm. My messages are often answered the same day, and I don't think I've ever waited more than a few days for an answer, even when it was a non-urgent question. I completely botched my financial forms when we got started, but Mayra called and patiently helped fix my paperwork. I am under a lot of stress from this high-conflict custody battle, so it's nice to deal with kind people who understand how the legal system works. I also love that they have an online case management system where you can send emails, upload documents, etc. It's nice to be able to access my pleadings whenever I want, and it helps me feel like I'm in the loop. I have worked with other attorneys who would just file things on my behalf and not even tell me, but that doesn't happen here.

Dishonest and untrustworthy attorney
Working with this attorney has been the worst decision made in recent years. The quality of service is abysmal and she has no business operating in the family law arena. Mayra has issues with taking accountability and is incredibly untrustworthy. She and her partner have scammed me out of almost $10,000. They present themselves as competent attorneys but they have done nothing but cause issues in the case they were hired for, resulting in an incredible amount of unnecessary stress and anxiety.
