O'Neill Law Firm, LLC

I was born and raised in the La Crosse area. I bought my first home when I was only 19 after coming home from a combat deployment in Fallujah, Iraq. I spent over 8 _ years in the Marine Corps reserve. Buying a home at a young age exposed me to the excitement and hassles of the home buying process. As an agent it is my job to take away that stress and give you the best experience possible.
It is my duty to be accessible to you at all times. Do not be afraid to text, email or call me late at night, early in the morning, or even on holidays. Communication is paramount, a trait the military engrained into my head and one that is reinforced in real estate. Whether youre buying your first home, selling your current home, or just have questions about homes please call me. I am dedicated to serving our country and serving our community, now let me serve you.
Interests: I enjoy jogging, volleyball, and riding my motorcycle in the summer. When the weather demands I remain inside I love bowling in leagues, working out and playing basketball at the YMCA, reading, playing board/card games, and I am a huge movie buff.
Community Involvement: I am a board member for the Young Professionals of the Coulee Region. A part of the Chamber of Commerce. I am a member and volunteer at the Onalaska American Legion. I am still in the Marine Reserves and plan on retiring in the reserves. I have been a guest speaker for Memorial Day and Veterans Day events in the local area. I enjoyed being a Dale Carnegie graduate and a coach.
