Let me help you get pre-approved today!

I have been in the mortgage business since 1978 and recently returned to loan origination after many years in sales and branch management. During my 37 years in the industry I have maintained numerous relationships with first-time buyers who have since purchased their second or third home, and I am now doing loans for their children and grandchildren.

I am a Butler University graduate with a degree in Vocal Music performance. Many of my musical endeavors have strengthened my mortgage business referrals, including my participation in the Indiana Opera Theatre, MacAllister Awards for Opera Singers, a tenor soloist at Zion Evangelical United Church of Christ for the past 27 years, Repertory Theatre at CTS, and Warren Performing Arts Center. I enjoy going to Purdue basketball and Indianapolis Colts games, the Lyric Opera of Chicago and trips to St. Louis for baseball and hockey.

My diversified interests make it easy for me to connect with my customers. My goal is to make the mortgage approval process as easy as possible for every customer and provide the highest level of service deserved by each and every applicant.

  • I love working with Mark Willen!!! Can’t say enough good about him! He answered any and all questions I had promptly and was always easy to contact, talk to, and was very understanding with me. I am not knowledgeable at all about these things and he does a great job “dumbing” things down for me! All reasons I chose him to complete my second mortgage loan! I would never want to use anyone else!

    Teresa W, happy client
  • Mark Willen is a warm and friendly guy with a lot of knowledge and a strong desire to provide guidance through the entire process. This is our second home through him.

    David D, happy client
  • My wife and I loved the whole process with Ruoff. After being misinformed by a different mortgage company, we turned to Ruoff because of a recommendation from a friend and it was the best decision we’ve ever made. Mark was beyond knowledgeable and helped us through every step of the process. This made the home buying process easier and more fun than we could have ever imagined.

    Nicholas P, happy client
  • Mark, was always very quick to return my calls or emails. He took time to explain everything each step of the way. I never worried once something wasn't going to get done on time.

    Carolyn H, happy client

    Lynne U, happy client
  • Mark did a great job of guiding me through this process. He met me in places that were convenient to my schedule and his goal was to make sure I was informed along the way until the time refinancing occurred. Mark is easy to work with and knowledgable about this field.

    Jill L, happy client
  • Excellent communication and service! Highly recommended!

    Mark & Elizabeth M, happy client
  • Everything through the whole process was very organized and painless. By the time we reached the closing date, it almost seemed like a formality. This was the easiest homebuying experience we could have hoped for. Mark and his assistant Jennie did an outstanding job for us. We were treated well and made to feel like doing business with us really mattered.

    Mark M, happy client
  • Mark Willen is my "go to guy" for a mortgage!
