Benjamin Joe Chambers, MD

Dr. Carter chose the field of psychiatry with the goal of empowering her patients and equipping them with the skills and tools to improve their mental health. She strives to create a safe, nonjudgmental space where patients feel heard and supported. She strives to destigmatize mental illness and normalize seeking help when struggling. Her passion for psychiatry stems from a deep interest in connecting with people and understanding their unique stories.

Dr. Carter believes the patient-physician relationship should be a partnership, built on trust, empathy, and shared goals. She encourages honesty, collaboration, and open communication, and believes there are no wrong questions, and your voice matters. She encourages questions and feedback and tailors care to each person’s goals, comfort level, and pace.

Dr. Carter wants to get to know the whole person, not just their symptoms. Together, she works with patients to create a personalized and thoughtful treatment plan that may include therapy, lifestyle support, and/or medication, always with room to adjust based on your evolving needs and preferences.
