I was introduced to Sarah Smith by Gary Cooper – a respected advisor on Mighty 1090 – a radio station I worked for as a traffic reporter for many years. Gary gave me his word that Sarah would do a great job for me and Sarah exceeded my expectations. Sarah worked with dedication and intention to sell my home quickly and at the best possible price.Read more

When we first met with you, you listened to our needs, asked for our pertinent info and then turned your computer screen around and showed us our plan of action. You showed us what steps we needed to take, exactly what we were able to afford and promised that, once we completed our to-do list, you would have us in a home within six months. Read more

Our Realtor was phenomenal! If you want someone who is on it and down to earth, this is the place! I don’t want someone to BS me and take me along on this crazy rollercoaster ride of home buying. He is your everyday honest friend. I want a Realtor who gets to know my style and does everything with integrity. He responds to you within hours and makes appointments a.s.a.p. I never had to wonder where we were at in our process because he was in constant contact with us. Above all, I am most impressed with his way of explaining things and patience for my questions. He's a rockstar, as is Gary. I would highly recommend this company to any of my family or friends.  Read more
