Miriam considers herself a life-long student above all else and is constantly seeking to expand her knowledge and expertise as a clinician.
Miriam’s approach has worked well for various needs, including (but not limited to) survivors of trauma, mood and anxiety disorders, body-focused repetitive behaviors, and those seeking to explore their sexuality and/or gender.
Outside of her practice, Miriam loves to read, practice yoga, explore New York City on foot, and perfect new recipes in her Brooklyn kitchen. Miriam also loves to sing and performs as a cantorial soloist.
