 I have never had to hire a lawyer. Maybe I have been lucky in that regard. But I’ve talked to a lot of people who have had the need to hire an attorney. I first noticed a problem several years ago when my sister had to hire an attorney to help her with a child custody and visitation court case. She was always complaining about how her lawyer would never call her back, didn’t do the things that he said he was going to do, and didn’t keep her informed of what was going on with her court case. Since then, I have heard complaints like that countless times. Especially that lawyers won’t call them back or talk to them. That was one of the many things on my mind when I founded my Law Firm. It wasn’t going to be like that. That’s why we make it a priority to return phone calls, keep clients engaged and up-to-date, and provide a client-centered approach to solving legal problems!

Marcy Fassio, Criminal Defense Attorney


If you’re looking at this page and reading this, it most likely means you are looking for a lawyer for yourself or a loved one because you found yourself in a bad situation, being charged with a crime. Trying to determine the right attorney to help you is one of the most important decisions you’re going to have to make during this process. So if you’re considering hiring my firm, it seems only fair that you should know a little bit about me. Sure, I can tell you all the stuff about where I went to law school; and I do, that’s down below. But I don’t know if that necessarily gives you a true feel for who I am. So let me tell you a quick story, which hopefully illustrates a little bit about the type of person I am, and the type of representation my firm provides.

I was a member of the Yearbook Club in high school. Maybe you think that makes me sound like a dork, maybe it does. But it is what it is. I should mention that we won an award for yearbook cover design in 1996. Go Wilburton Diggers! Yes, my high school mascot was the Digger. Anyway, our club was going to a yearbook convention. (Yeah, this definitely makes me sound like a dork.) As we’re on the school bus rolling up to the conference center, my yearbook advisor tells me and my best friend, Kristy, that she just found out there’s a trivia contest at the conference and each school has to participate. She says that she knows she didn’t tell us about it or prepare us for it, so she definitely doesn’t expect us to win, but she’d like us to participate.

Here it is, this is a big part of who I am. I could have just said okay, and rolled with it, coasted through the trivia contest, guessing at answers, or not even trying. But no, I took this as a challenge. I don’t sit back and watch as things happen, especially when they’re important, I get in and get involved and put in the time and effort to try and get the result that I want. So with the very limited amount of time we had between rolling up in the school bus to the conference, and actually competing in the trivia contest, I studied the material. And then I studied it some more. Yeah, I know, I’m definitely sounding like a nerd, you probably would have hated me in high school. But this is exactly why you want to have me as your lawyer.
Ready for the punchline?  You guessed it, my best friend and I won the trivia contest! We had no preparation, our teacher didn’t expect us to win, but I had drive and commitment and fight. And a willingness to work. So we won the contest. I think we ended up getting like a $500 credit to use to develop our yearbooks. And like I said earlier, we won best design that year!


Just so you know that I’m not a complete nerd, later on that same trip, my friend and I snuck into the school bus and opened the hatch on the roof of the bus. Then I was able to climb up and stand on the top of the school bus. My friend was able to take a picture. I got in a little trouble, but it made for an awesome picture! And I even got to print it in the yearbook.

I believe in always getting better. I want to be better tomorrow than I am today. I consistently set goals, both for my practice and my personal life. For example, right now my goal in my personal life is to improve my physical fitness. I believe the stronger I am physically, the stronger and better every other aspect of my life will be. I strive and work to be strong: physically, mentally, and emotionally. I’m working to increase my muscle mass! It started as a thought, became a thing, and now it’s a habit. I follow the same philosophy with my law practice. Think up a strategy, materialize it, and see it through.

Ok, now here is the serious stuff:
