The entire office is the best. Great Dentist and the staff is so friendly and professional at the same time. The Dentist is clearly not my favorite thing to do but Grout makes it as pleasant as possible.

The staff is always so friendly and very skilled at their jobs. The office is clean and organized and the staff really care about the patients and their comfort level while being treated. They offer advice to help improve the way you care for your mouth to avoid serious problems requiring fillings. They offer a senior discount if you pay with cash or check right after the appointment is concluded. We are grateful for the care we have gotten for almost 20 years.
Thank you Grout Family Dentistry!

Excellent establishment with the utmost integrity. With the rampant soulless corporate take over of many dental practices, it's more important than ever to support your local dentist. Guaranteed, you will receive better and far more genuine care here than being a number to a corporate office. Dr. Jeff is personable, professional, and to the point. Highly recommend this practice.

My family and I have been going to Dr. Jeff Grout for so many years, Ive lost count. I entrust my teeth with Jeff and his staff and they always do a great job from cleanings and exams, to fillings and crowns. He is a conservative dentist who keeps a close eye on changes to your teeth, recommending when the time is right if a tooth needs more than just watching. He and his team are knowledgeable, gentle and thorough.

Timely, informative, friendly and thoughtful experts. From the office staff to the dental hygienists and dentists, this practice is so professional and intentional. Nothing is ever forced, shamed, or questioned. Everything is explained, cared for, and provided options. The most considerate and kind dentistry I have ever been to. Everyone I have recommended it to has enjoyed their experience as well.

Had a chip in my front tooth, it had been fixed twice by another dentist. Not only was I seen the next available time slot, the filling in my front tooth looks so much better than the other 2 repairs, and Dr Jeff made it stronger, too. Hes a great dentist, the staff is super nice too.

What a fantastic team! I was greeted by Sam at the front desk who introduced me to the other staff And I was welcomed with smiles. Regan and Dr. Kack listened and treated me with patience and understanding. I am so glad I followed up with this stellar reference. I look forward to making GFD my regular dentist office and to getting my teeth cleaned by my all-time favorite hygienist, Kelly!

I've been going to Grout Family Dentistry for several years now and I highly recommend Dr. Jeff Grout and his staff for your Dental care. Everyone in the office is kind and welcoming and Dr. Jeff does GREAT work. I appreciate the care he takes as he explains what he's doing as he's working. Shout out to Sam, one of Dr. Jeff's Assistants. Dr. Jeff was about to put the permanent crown in and I didn't even realize Sam had already taken off the temporary crown! I don't live near their office, but I am happy to make the drive to Broadway and Mineral. Go see Dr. Jeff, you'll be glad you did!
