Get to Know Me
I am a licensed clinical psychologist and certified tobacco treatment specialist with a national certificate in tobacco treatment practice.
I am a passionate and committed clinician with expertise in evidence-based tobacco dependence treatments. These typically involve combining counseling with medications approved by the US Food and Drug Administration for quitting tobacco use. I am working with MSK’s Tobacco Treatment Program to expand telemedicine counseling for tobacco dependence to MSK’s regional sites.

I have a broad range of experience in behavioral health, addiction, cancer care, and lung cancer screening. One of my specialties is providing group tobacco treatment counseling in healthcare and workplace settings. My research interests involve using group counseling to help people quit tobacco products and making tobacco treatment services part of lung cancer screenings.
I currently serve on the Board of Directors of the Association for the Treatment of Tobacco Use and Dependence and as Co-Chair of its Business Practices Committee.
A psychologist has special training in therapy to help people with mental and behavioral health issues.

I appreciate MSK for their care of my case, myself and their attention to details.
I enjoyed our conversation. Mr. Kotsen spoke about the process it takes to completely to stop smoking and handling the urge to smoke.
I had a great and lengthy communication with my providers on my case and was totally satisfied by the answers to my concerns.
I wasn't even aware there was a nose spray to help you stop smoking and they informed me about it or the side effects or the information on it and I'm going to try it. I never knew about it so he was the only doctor that ever mentioned something like that and I really do appreciate it. Bye.
He listened to me. Did not judge my lack of control for smoking. Gave me some good tips to help me stop and think about. Formed a plan that seems reasonable and gives me a good chance to stop for good.
