The staff is always friendly and accommodating, and they consistently get me in for appointments right away. What I appreciate most is that they offer a full range of dental services in one place—from cleanings and crowns to root canals and extractions. I am so glad we made the switch a year ago and couldn't be happier with the care we've received.

Dr. Gwinn and his staffs are so nice, quiet and clean place. He’s very detail and find the way works for my nose. Couldn’t smell for a long time. He did nasal surgery for me. Now I feel like I got my life back, more energy and happier. Thanks to my family doctor who’s referred me to him. Thanks to Dr. Gwinn and his staffs. Highly recommend.

This was my first time at Knollwood and from the moment I walked in until the moment I left the experience was amazing. I have never had such a thorough and informative cleaning, thank you Teresa. Everyone was so nice and welcoming

This is truly one of the best dental offices I’ve ever visited:
From the moment you walk through the doors until the moment you check out, the entire experience is filled with comfort, kindness, and genuine care. Every staff member greets you with a smile and makes you feel at ease.
I’m now going on my third visit, and honestly, I wouldn’t trust anyone else moving forward.
As someone with dental anxiety because of past negative experiences in both dental and medical settings, Dr. K has been such a blessing. They always keep me calm during procedures and make me feel safe, respected, and heard.
I truly recommend this office to anyone looking for a gentle, patient, and trustworthy dentist. They’ve completely changed the way I feel about going to appointments.

Great friendly comfortable atmosphere, besides the care is outstanding. I have been coming here for about 60 years. (Dr. Marecki was the original doctor when I started coming here). I have no unpleasant thing to say about this practice. The staff is always welcoming, I couldn’t possibly name all of them. They are all great.
