  • review rating 5  Dr. Ferrin is a godsend. I switched over to him after an discouraging experience with the last periodontist that I met with. I was really nervous at first, but Dr. Ferrin and his staff were very kind and comforting towards me. They went out of their way to make me feel at ease. I’ve only had one appointment with Dr. Ferrin and I trust him. I would definitely recommend him to anyone if you have to have a dental procedure because he is the perfect example of a medical professional in that area.

  • review rating 5  September handled my quarterly cleaning today in a particularly human way. I have been suffering from a bad case of shingles on the right side of my head and she went out of her way to make my cleaning as painless as possible. Thanks again.

  • review rating 5  You can feel comfortable and secure that you are receiving the best treatment possible with Dr. Ferrin and his amazing team. I have needed multiple procedures, and have not always had the best experiences in a dental chair, -therefore I do know the difference. I instantly felt at ease when I walked into Dr. Ferrin's office. He is professional, sensitive, and shows a genuine passion for his work. I have never experienced a "specialist" who truly thinks in the grand concept for the health of his patients, instead of just completing the task he is trained to perform. This passion and professionalism trickles down to all the staff in his office. They are all friendly and upbeat, which further exudes that feeling of confidence and comfort; and are obviously happy to be a part of his team. They are well-trained in explaining a specific and detailed financial plan when necessary, and are always available to answer questions. THEY MAKE ME FEEL LIKE A PERSON, -NOT JUST A PATIENT. Dr. Ferrin does exceptional work, is empathetic, and we are truly blessed to have his service in our area. I felt compelled to share my positive experiences online for those who are apprehensive or just looking for re-assurance to get the best periodontal care possible. Dr. John Ferrin and his staff are awesome!

  • review rating 5  I never thought I'd need a gum graft (or that I'd write a review for one!), but thankfully, there is Ferrin Periodontics. Dr. Ferrin is kindhearted, empathetic, and highly skilled. He clearly presented my options and did a stellar job with the procedures. He and his staff are grand; they take the "scary" of grafting. If you've gone down the rabbit hole of Internet research and emerged worried, I am happy to say my experience was 10 times better than I thought it could be. You'll be in good hands.

  • review rating 5  Thank you Dr. Ferrin and staff for a first class experience. Everyday I examine the gum graft surgery spot and am so amazed at the difference. My gums are now very youthful and healthy looking!

  • review rating 5  I gave Dr. Ferrin and his staff a five rating for the family atmosphere and professionalism I experience every time I go there. I had a crown Lengthening procedure and I couldn’t be more please with the out come. I was impressed with the way my general dentist and Dr. Ferrin both collaborated and gave/give me the best care possible. My treatment treatment is now ongoing due to my periodontitis diagnosis. I have regular cleanings with Heidi every 4 months and my teeth never felt more healthy and with their help I have been able to save all my teeth.
