Founder, owner and Medical Director of ADHD Boston since 2004, he has evaluated and treated thousands of adults with ADHD.

My mission is to improve the quality of life for adults with ADHD. I have spent well over 10,000 hours meeting with people who struggle with distraction, procrastination, and disorganization. The amazing positive changes I have witnessed over the years continue to inspire me, and I feel very fortunate to have met with and learned from so many intelligent, creative, and interesting people.

I absolutely love specializing in ADHD. No other diagnosis is as diverse, complex and fascinating.
