I hired Mark for my husband and let me tell you, he is darn good at what he does! Not only was Mark honest, but we always knew all the possibilities along the way of what could happen during the case. Don’t even get me going on Jeanette. She’s an absolute dream. She always answered my calls or texts.And not only is she good at her job too… she made it personal. She would ask how I’m doing and make sure I was okay every step of the way! If you want an aggressive attorney who’s honest and will get you the best outcome, HIRE Mark and his team !!! I promise they treat you as if you are their own family. I love the entire team! Thanks for representing my husband and getting us the absolute best outcome there ever could be !

Mark and his office saved my life. I had a very high profile case and the Government was hell bent on destroying my life and imprisoning me for a very long time. I was innocent and this was my first time being arrested. Before I hired Mark, The Government refused to give me bond and held me in jail for over two years. The jail treated me horribly and I was always in the hole. Before Mark I had four different lawyers representing me. I let go of them all because none of them fought for me, I was just another number to them. One lawyer only visited me once in six months, stayed three minutes, and didn’t know my name. Another lawyer refused to believe me and wanted me to take a plea to go to prison for ten years. Three months before my trial I hired Mark O’Brien and my life took a 180 for the best! Unlike every other attorney Mark and his team made sure to pick up the phone and answer all of my concerns. He visited me in jail consistently and he talked to the Warden multiple times on my behalf. I was treated with respect at the jail for the first time. The guards no longer harassed me because they knew Mark would step in. Mark and his team communicated with my family constantly. Mark made sure my suit went to the dry cleaners to assure I looked good every day in court. Mark only had a couple of weeks to prepare for trial he exposed every lie and trick the Government did against me and totally destroyed their case against me. I was released three months after hiring him, right before Christmas just like Mark said I would and spent it with my family. I was in jail for two and a half years due to bad representation. One of my previous attorneys event contacted me afterwards and said “I understand why you fired us, only Mark could have gotten you that kind of outcome.” Mark freed me and prepared housing for me until my family was able to pick me up. When the police heard I was released they were so upset and embarrassed, they tried to arrest me again ..twice, but Mark put a full stop to that and I’m free because of him today. Mark and his team are truly the best! Take it from me I have had many lawyers. Even though I was innocent the other lawyers were scared of how many resources the Government were using against me and didn’t want to do the work to get the job done right. Without Mark I would have went to prison for a very long time for something I didn’t do. He is simply the best and I know this because he helped so many other inmates in jail get justice as well. Federal inmates weren’t going home if they didn’t have Mark as a lawyer. I recommend him highly.

What Questions Should I Ask Before Hiring a Lawyer?

Hiring the right lawyer is crucial for the success of your case. Here are some important questions to ask during your initial consultation:

  1. What experience do you have with cases similar to mine?
    Ensure the lawyer has relevant experience in the specific area of law pertaining to your case.
  2. How do you charge for your services, and what are the estimated costs?
    Understand the fee structure, including hourly rates, flat fees, retainer fees, and any additional expenses.
  3. Who will be handling my case?
    Find out if the lawyer will handle your case personally or delegate tasks to other attorneys or paralegals.
  4. What is your approach to resolving cases like mine?
    Learn about their strategy, whether they prefer negotiation, mediation, or litigation.
  5. What potential outcomes can I expect?
    While no lawyer can guarantee results, they can provide an assessment of possible scenarios based on their experience.
  6. How will you communicate with me throughout the process?
    Establish expectations for updates, preferred communication methods, and response times.
  7. What is the expected timeline for my case?
    Get an estimate of how long the process may take from start to finish.
  8. Do you have references from past clients?
    Testimonials or references can provide insight into the lawyer's professionalism and effectiveness.
  9. What challenges do you foresee in my case?
    Understanding potential obstacles helps you prepare and sets realistic expectations.
  10. Are there alternative ways to resolve my legal issue?
    Discuss options like mediation, arbitration, or settlement to resolve the issue efficiently.

Can a Lawyer Represent Me in Courts Outside of Tampa, Florida?

Whether a lawyer can represent you in courts outside of your city or state depends on their licensure and the jurisdiction of the court:

  • Within the Same State:
    Lawyers licensed in a particular state can typically practice anywhere within that state, including all cities and counties. They can represent you in both state and federal courts located in that state.
  • Outside of Their Licensed State:
    If your case is in a different state, the lawyer must be licensed in that state to represent you. However, there are exceptions:
    • Pro Hac Vice Admission: An out-of-state lawyer can request special permission to represent a client in a specific case in another state. This requires filing a motion with the court and often working in conjunction with a local attorney.
    • Federal Courts: If your case is in federal court, a lawyer licensed in any state may be able to represent you, provided they are admitted to practice in that particular federal court.
  • International Representation:
    For cases outside the United States, different rules apply, and the lawyer may need to comply with the foreign country's legal requirements or collaborate with local counsel.

It's important to discuss your specific situation with the lawyer to determine if they can represent you in the desired jurisdiction and what steps may be necessary to do so.

How to Check the Credibility of a Lawyer

Before hiring a lawyer, it's crucial to verify their credibility and ensure they're qualified to handle your case:

  • Verify Their License:
    Check with your state's bar association to confirm the lawyer is licensed and in good standing. Most state bar websites have an online directory for this purpose.
  • Experience and Specialization:
    Ensure the lawyer specializes in the area of law relevant to your case. Review their website, professional profiles, and case history.
  • Disciplinary Record:
    Look up any history of disciplinary actions or complaints through the state bar association's records.
  • Client Reviews and Testimonials:
    Read reviews on legal directories like Avvo, Martindale-Hubbell, Google, or Yelp to gauge client satisfaction and experiences.
  • Professional Memberships:
    Membership in professional organizations or specialty bar associations can indicate a commitment to their field and adherence to high ethical standards.
  • Awards and Recognitions:
    Honors from reputable organizations reflect expertise and a positive reputation in the legal community.
  • Consultation Assessment:
    Use the initial consultation to evaluate their communication skills, responsiveness, and willingness to address your concerns.
  • Ask for References:
    A credible lawyer should be willing to provide references from past clients who can speak to their abilities and professionalism.

What Should I Prepare for My First Consultation?

To make the most of your initial meeting with a lawyer, come prepared with:

  • Relevant Documents:
    Bring all documents related to your case, such as:
    • Contracts or agreements
    • Correspondence (emails, letters, texts)
    • Legal notices or court papers
    • Financial records (if applicable)
    • Evidence (photos, videos, receipts)
  • Written Summary:
    Prepare a concise written summary of your situation, including key dates, events, and parties involved. This helps the lawyer quickly understand the context.
  • List of Questions:
    Write down any questions you have about your case, the legal process, fees, or the lawyer's experience.
  • Financial Information:
    If your case involves financial matters, bring relevant documents like pay stubs, tax returns, bank statements, or invoices.
  • Contact Information:
    Provide details of any witnesses or other parties relevant to your case, including their names and contact information.
  • Personal Identification:
    Bring a valid photo ID for verification purposes.
  • Pen and Notebook:
    Take notes during the consultation to remember important points discussed.
  • Budget Constraints:
    Be ready to discuss your budget and any financial limitations so the lawyer can provide appropriate guidance on fees and payment options.
  • Openness and Honesty:
    Be prepared to discuss your case candidly. Full disclosure allows the lawyer to give accurate advice and anticipate potential challenges.
