Patient Reviews

Vibe


The staff was prepared when I told them I have bad dentist anxiety and haven’t been to the dentist in years. I’ve found my forever dentist, and I would 10/10 recommend!

Ciara Was


Being new to the Pittsburgh area, my husband and I were looking for a dentist close by. Our realtor recommended Dr. Marion, and I am so thankful she did.

Kathy Makepeace


Today was my first visit, and there is no doubt that I will go back. As a matter of fact, I have already scheduled my next appointment.

William McGeehan


I needed gum treatments and two extractions. I now understand why the Marion Smile Center receives such high praise: they earned it!

David Green


We’ve recommended friends and family of all ages, from ages 4 to 94. Every person we’ve recommended has been 100% satisfied with the services at Marion Smile Center.

Chloe Huber


My 3-year-old loves Dr. Marion and all of the staff – she actually looks forward to her cleanings! She even wants to be a dentist when she grows up because of how incredible Marion Smile Center is.

They take the time to make sure kids feel 100% comfortable and have a positive experience.

The staff is so warm and friendly. We love everyone at the office, and it is always a happy experience. I actually enjoy going to the dentist now!

Dr. Marion took his time and at no point did I feel I wasn’t his main priority. He was gentle and comforting throughout the procedure.

Teresa Schultz Gomori


I am always so nervous before a dentist appointment – but not at Marion Smile Center. From the time you walk in the door to the end of your visit, you are put at ease.

Michelle Makepeace

Kristen Hogan


Dr. Marion has a very calming demeanor and is very gentle. He always makes sure you know why he is doing any procedure. Give them a try, and they will change your mind about dentistry.
