Dr. Karen Lederer
BScN, DDS
It’s in my nature to want to achieve the best possible results for my patients—it has been since my first career as a Registered Nurse. I learned a lot about myself during that time, like how I thrive in team-oriented settings and when I do something, I like to make sure it’s done right the first time.
I decided to get into dentistry so I could channel my desire to help people and get back to patient-focused care. I was able to take what I learned in my years as a nurse, like the importance of building rapport and taking my time with patients, and bring that into my dental profession so I can ensure my patients truly feel cared for.
To me, there is artistry in dentistry. I love making every smile its own masterpiece. At the same time, I am supportive of functionality too, so my patients get the best of both worlds.
Yes Dental is built on the belief that every patient should be presented with options for their care so they can make informed decisions and feel comfortable knowing they are in control of their dental health.
