Psychiatry and therapy in Greater New England.
Visit our Acton office or meet by telehealth from Massachusetts or New Hampshire. We also offer care for people affected by cancer.
Our approach to care
We view therapy as a collaborative journey, where we partner with you to navigate life's challenges. We understand that you are the expert on your own life, and our role is to listen attentively and support you every step of the way.
Our services include medication management and psychotherapy, complemented by a compassionate focus on the unique challenges faced by cancer patients. We value the interconnectedness of mental, emotional, and physical well-being, integrating strategies that honor all aspects of your health and lifestyle to support a fulfilling life.
