Dr. Rennicke is a Columbia University trained clinical psychologist working in the vibrant Soho neighborhood of downtown Manhattan.

Dear R&A Community,
I was feeling a little sheepish about this newsletter coming out late this month, but then I reflected on the cosmic sea change we have gone through as a country since the election and reframed with a bit more self-compassion, “Yes it is late, Courtney, and it has also been a rough month.” I wanted to directly comment on the election in our newsletter, to see if there was some way to make a little sense of it, however here we are six weeks later and I really don’t know what to say. There is so much to say, there is a litany of things to do and to protest and yet…I feel no clarity or integration of the bigger picture, do you?

Anxiety, Depression and Bipolar Disorders
Post-Adoption Issues and Parent-Child Attachment Related Concerns
