Instituted a cutt-throat 48 hour cancellation policy with a $150 fine that comes in as a contract to sign. Been there for over 6 years. Standard for doctors and dentists is 24 hours-When you have multiple children running in multiple directions that 24 hour standard policy is a welcome friend.
Not a friendly dental practice for working moms.

Everyone at Brentwood Dental is professional and so gentle and caring. Dr. J is a wiz and I love that she looks for whole health solutions rather than going the surgical route straight away. I have always had an excellent experience with the hygienists as well. This is a top notch facility. 👍

Best move I ever made moving to BDD. Dr Johnson and the whole staff are very caring and knowledgeable. My teeth would be a lot better if I went to them sooner.

So kind, professional, and gentle! They are a wonderful team who specialize in more natural options and healthy recovery. I have had a lot of work done on my teeth (half way done), and I couldn’t be more than pleased! The first time I looked in the mirror at my white teeth instead of that black mercury, I literally teared up! It was so worth every minute, and I left feeling confident in not only my smile but the work that had been done. I would give them more stars if I could!

This office has exceeded my expectations, to simply put it. The time and care that was given to me was genuine and thoughtful. Rachael took the required time getting to know me, which allowed her to tailor her care to what I needed. The other members of the team were just as outstanding.
This office has a focus on your well-being and your health. They have the know how, tools, experience and desire to give you the best dental experience.
This practice was highly recommended to me and I am also highly recommending this practice.

I've always had great experiences at Brentwood Dental Designs even when the procedure has been intimidating. Everyone there has such compassion and knowledge, it's easy to relax. This is a state of the art facility - a role model for other practices to emulate. Fees are reasonable and comparative but with a higher level of treatment. I recommend Dr. J. and her staff to all my friends, can't say enough great things. Thank you Doc and all your staff!
Of particular importance: During this pandemic, Brentwood Dental has taken extraordinary cautions creating a safe environment for everyone!

It is hard to describe the level of comfort that I had while visiting Brentwood dental designs. The care and Customer Service is above anything I have ever experienced in my life. My hygienist Rachael explained everything in detail, all the processes-and I was so comfortable with everything that it was a 100% fantastic experience. The safety and care that is taken with each patient is above anything I have ever experienced before and I am so glad that my wife and I chose to come here and have are not only oral health but whole body health attended to.
