We were referred to Mike Cox at GSF by our awesome realtor Jenny Ballwahn at Full House Realty. What a stroke of good fortune! The GSF team accomplished for us what four other institutions could not or would not do. We are deeply grateful to Mike and his team at GSF for the great service they provided in helping us into our new home.

“I rarely meet a "professional" within a profession anymore. So, when someone really shines and exceeds my expectations, I have to share my experience so that others may have the same opportunity. I am referring to Pam Gustafson and the team at GSF Mortgage who assisted us in a refinance with a VA Loan. The service we received was 10-star to us! Pam maintained excellent communication with my questions and with all the people involved in my lending experience (which was very challenging!) If something had to be done, she was on it! In addition, we had another house that was closing after our Refinance and she worked with the title company to assist us in associated closing details. The title company made a comment about how great Pam was to work with. Thank you, Pam, for taking care of all the things that came up. It was reassuring to know you were there because I had faith that you would get it done! And you did, every time! By assisting us with this loan, you have made our lives so much better and we cannot thank you enough. For those in need of a mortgage, we give Pam and GSF Mortgage our highest recommendation! Thanks again, Pam!!”

“Pam was such an amazing person to work with. We wouldn't be where we are today without Pam help, especially when we kept getting turn down in the past. Very helpful and answer every single question we had. Being first time home buyer, we were very nervous about everything and Pam was there every step of the way to reassure us that everything was going to be okay. We would definitely recommend Pam to family, and friends for future home buying. Pam made our first-time home buying experience the best.”

“Our experience working with Pam was amazing. She was so helpful and personable and she made our first-time home buying experience such a positive one. The information she gave us really helped us make an informed and confident decision on a mortgage that fit our needs and was in our best interests. Thank you, Pam, for all the hard work you did for us. We love our new home!”

“I was referred to GSF by my mother who is a realtor. She had had great experiences working with GSF through her clients, so when my husband and I decided to buy a home using a VA Loan, GSF was who was recommended to us. I can honestly say, they made the home buying process easier than we EVER thought it could be! Pam Gustafson was our loan officer (who we were referred to) and she was amazing from the beginning! She did our pre-approval in a matter of minutes and kept us in the loop EVERY step of the way. She answered all of our questions (and as first-time buyers, there were a LOT!) in a timely manner, a professional manner, and with a genuine desire to see us get through this process and wind up in the home we had chosen. Amy Coppus was our loan processor and to say she 'knows her stuff' or is 'on the ball' wouldn't quite cover it. Again, timely responses to questions (lots!), professionalism, efficient, and kept us in the loop every step of the way! Pam and Amy were quick to assure us that everything we were providing to them for documentation was normal and why it was needed, they told us ahead of time what to expect and when to expect it and what everything meant. We closed on our home on time with no delays and no 'mishaps' due to the amazing organization and efficiency of Amy and Pam, and their team at GSF! We couldn't be happier with the service we received from Amy, Pam, and the staff at GSF--they truly helped us make our dream of finally buying a home a reality!”

“I would highly recommend GSF and Pam Gustafson to anyone looking for a mortgage loan. They have a lot of options and can surely find the one that best suits your needs. Once Pam had the information she needed for pre-approval there was very little I had to do from there except digitally sign paperwork from an easily accessible secure web site. They made the entire process easy for us as the buyers and communicated tremendously with our realtor to make the entire process seamless with little work from us. I appreciate how personal they made the experience for me and my wife even though they had multiple other customers they were working with at the same time.”

“I couldn't be happier with my choice to finance through GSF. Brian got me a much better deal than the other lender I started the process of doing a VA loan with, and made the process very easy. He explained everything in great detail and left me with no surprises.
He fielded every one of my dumb questions with a smile and reassured me when we got a few bumps due to needed repairs on the home. He then made sure everything went through at the end when it came down to the wire due to those repairs taking longer than expected.
I can't recommend these folks enough. Ask for Brian!!”

“My husband and I worked with Brian Hofmann from GSF and he made buying our first home so easy! Brian made sure to provide the best opportunities for us to make buying our first home easy. He was always readily available and willing to go above and beyond to make sure my husband and I received the mortgage we needed for our dream house! I would highly recommend working with Brian and GSF mortgages!”

“My husband and I had an amazing experience working with Tyler Beckman at Beckmen Properties along with Brian Hofmann here at GSF Mortgage. It was an easy process and was always kept in the loop!! Brian never once hesitated when we had questions to ask him, he always had answers for us and reassured us when we were in doubt! If I could go through it all again for the first time I would!!! Highly recommended!!”

“Brian was awesome to work with! My wife and I had been working with another branch when we discovered they were trying to pull a fast one, and Brian jumped right in. In a matter of a week we were pre-approved for a loan and he help raise out credit scores. Being a first-time home buyer Brian and GSF Mortgage Fox Valley made it easy and made us feel good about making the biggest investment. Thank you, Brian, and GSF!!”

“Brian Hofmann and GSF Mortgage were amazing to work with. The process is so easy and no headaches. We enjoyed working with Brian, so much so that we are currently working with him again! Super knowledgeable staff, friendly and they have great snacks in the office. If you are in the home buying market, give him a call. Oh, and if you are a veteran, they very much recognize it and appreciate your service.”

"My husband and I had a fantastic experience working with Scott Bonovich on the purchase of our new home. From beginning to end, he was informative, extremely thorough and attentive to our financial needs, making sure we understood the process and educating us on our financing options to help us secure the best loan program for our needs. He went above and beyond in advising us on what we needed to do to improve our credit to secure our loan. We appreciate everything Scott did for us and we highly recommend him to anyone buying a home!"
Danial & Michelle | Mortgage in Neenah, WIContact Scott
"My husband and I recently used Scott for the purchase of our first home. We didn't understand anything about the mortgage process when we started. Scott was extremely knowledgeable, patient, and attentive with us and made us feel very comfortable during the home buying process. He recommended and referred us to a realtor to help us find the perfect home. Scott was always available to answer any questions we had and that was very important to us being first time home buyers, the process sure can be stressful and intimidating. We are so glad we chose Scott and would strongly recommend him to anyone thinking about buying a home"
Tony & Erica | Mortgage in Appleton, WIContact Scott
"Plain and simple, Scott is one of the best at what he does! I tried working with my bank, but was very frustrated at their inflexibility and lack of guidance. I had challenging circumstances throughout my home buying process and Scott guided me every step of the way and was there to reassure me that everything would work out. His professionalism and knowledge throughout the mortgage process was invaluable. I don't know how I would've gotten through it without him! I appreciate everything he did for me and I highly recommend him to anyone looking for a mortgage. Scott is exactly the type of person you want working on your behalf"

“We were recommended to Jake from GSF through my previous employer after running into financing problems with our current lender that we had been working with for 8 months! Jake was SPECTACULAR! He always has a positive outlook, was compassionate about our situation, gave great advice, and always seems to be available when needed to answer questions. He was also great at keeping us updated, even if nothing had changed, just to let us know they were still working on things. Plus, he caught something at our closing that saved a little more money! We have stayed in contact with Jake to refinance in the near future and he has given us so many tips on financial planning! He’s a miracle worker!! We are so glad we got the chance to work with him....it was a relief to have something good happen!!”

“I worked with Jake Knuppel at GSF and the entire process was very professional. I, like many, ask a million questions when it comes to spending money, and having little to no knowledge of mortgage loans, I asked a lot. Jake and the guys at GSF were patient and always helpful in explaining things in detail.”

“Jake Knupple was so helpful during our first home buying process! He made everything a breeze. We are extremely happy that we went through GSF mortgage, and that we had Jake to help us.
