Mark and his team are fantastic to work with. Mark is extremely knowledgeable about the local market. He is also very helpful in giving guidance around making improvements to a property. He listens and he cares...and is willing to go the extra mile. I give him and his team my highest recommendation.

We were so impressed with Mark and his team! Having used his expertise to sell two homes, I urge anyone who is looking for a dedicated hard working realtor team to call The Mark G Group!

It was a pleasure working with Mark G and his team on the sale of my house. The team was always very professional and efficient. Communication throughout the process was timely and clear. Selling a house is a stressful situation, but Mark and his team made it a pleasurable experience.

Mark and Rachel were a great team to work with. They were prompt, efficient, and available at any time. Mark sold our home within two weeks at asking price. Rachel was available around our busy schedule and showed us homes in the evenings and on weekends. She made sure everything was advancing smoothly during the transactions. They both kept in constant contact with us and they have a great process in place from first contact through closing. We couldn't be happier!

Rachel was amazing, I was looking for just the right house and the one I fell in love with was sold before I could offer, unfortunately for them the financing fell through and Rachel rushed out to get me a showing at 830 at night that same day and we offered that night. She was amazing at preventing the loss of this house again! I just moved in last week and am so happy

Far superior from other experiences with Realtors - Mark and his team really care about helping us to sell the house. I never felt like just another listing - but that Mark and his team genuinely cared about our goals and really put in the effort to help us be successful.

We had a very good experience with Mark Greskowiak as our realtor. He is very knowledgeable and personable. You can approach him with anything (even if is just to vent), and he is patient, kind, and understanding, all while being professional. He always appears positive and upbeat, which can set you in a better mood. We would recommend him to others in a heartbeat.

His sales record and advertisement on the radio spoke for itself. Mark gave us a few things to fix the inside of the house we complied and within the first week of being on the market we had a buyer. The support staff is excellent, very friendly and very knowledgeable. We had a different agent before and couldn't sell the house in 7 months. Mark sold it within the first week on the market. We couldn't have done any better than that.

I had just an over all good experience with the G Group. Mark Greskowiak and his team always made themselves available when I had a question. They sold my house in a short amount of time and for a price I was happy with. I would use the team again and would recommend G Group to others. ~ Rob Hudec Burt, Michigan

Buying a house from out of state was sure to be a complicated task. I have an extremely busy work and travel schedule. Janice Arends was a pleasure to work with and made the distance a non-issue. She always advised the next steps and prepared me for what was to come. I'm grateful for Janice and all of her help assisting me buying a home in Saginaw, MI. I would highly recommend her to anyone purchasing a home.

Mark and his daughter Rachel are top notch professionals. Sold my house in three months and it was in a flood plain! Worked hard to get me into the houses I wanted and for the price I wanted. I cannot speak highly enough about the Mark G group.
