Celine Corona, MD

Staff Psychiatrist

Dr. Celine Corona is a psychiatrist who earned her medical degree from the University of Santo Tomas in the Philippines. She completed her psychiatry residency at St. Elizabeths Hospital in Washington, DC, followed by a child and adolescent psychiatry fellowship at the Icahn School of Medicine at Mount Sinai in partnership with BronxCare Health System in New York. Dr. Corona is double board certified in adult psychiatry and child and adolescent psychiatry by the American Board of Psychiatry and Neurology. After training, she joined a group private practice serving patients of diverse ages and backgrounds and continues to occasionally oversee fellows and their cases at an outpatient clinic at BronxCare.

Dr. Corona strives to create a warm, calm, and supportive environment where patients feel validated and genuinely cared for. Her approach is largely psychodynamic, with an emphasis on understanding the psychological roots of behavior patterns and how past experiences shape present functioning. She views each patient holistically, considering lifestyle factors alongside emotional and psychological concerns, and often incorporates psychodynamic therapy, cognitive behavioral therapy, and mindfulness-based practices.

During the initial intake, Dr. Corona carefully explores the patient’s presenting concerns and conducts a comprehensive review of medical, psychiatric, and psychosocial history, including developmental history for child patients. She discusses her assessment openly, values patient input, and collaborates closely with each individual to develop a personalized treatment plan aligned with their goals and unique circumstances.

Anastasia Ruiz, MD

Staff Psychiatrist

Dr. Ruiz is a compassionate psychiatrist specializing in adult and maternal mental health. She develops personalized treatment plans to address anxiety, depression, bipolar disorder, ADHD, OCD, PTSD, PMDD, and perinatal conditions. Her goal is to help patients reconnect with their values and live balanced, fulfilled, and meaningful lives.

Her passion for medicine began in childhood, inspired by curiosity about the mind and body. She earned an Honors Chemistry degree with  magna cum laude and completed her medical training and psychiatry residency at Texas Tech University Health Sciences Center. With a strong scientific foundation, Dr. Ruiz understands the role of medications, and embraces holistic healing through connection, gratitude, and spirituality.

Dr. Ruiz has experience in diverse clinical settings and has received national awards including the AWP International Fellowship and ADMSEP Innovations Award. She is dedicated to advancing maternal mental health screening and treatment through clinical care and education.

Dr. Ruiz combines pharmacotherapy (medication) with psychotherapy to create individualized treatment plans. Therapy provides powerful tools to manage thoughts, emotions, and behaviors that support balanced brain chemistry. Research shows that medication helps restore this balance more quickly and effectively, especially in moderate to severe cases.  

Dr. Ruiz likens medication for the brain to fertilizer for a garden. Imagine your mental health as a vibrant garden—when well-nourished, it can thrive with resilience, beauty, and balance. But when symptoms like depression, anxiety, ADHD, or mood instability take hold, they act like invasive weeds, crowding out healthy growth and making it hard to enjoy the space. Medication acts like fertilizer, strengthening the garden’s natural systems so the healthy parts can reclaim their place and flourish. Just as some gardens need only seasonal care while others require more consistent tending, medication plans are personalized to support each person’s long-term mental wellness. When the garden is healthy, there's more room to grow, connect, and fully enjoy life.

With a strong background in chemistry and pharmacology, Dr. Ruiz prioritizes educating her patients about how medications work and why they can be helpful. She believes patients should take an active role in understanding their diagnosis and treatment. Her approach emphasizes diagnostic clarity, medication management, patient education, and brief psychotherapy based on cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT).

Your first appointment is a supportive, in-depth conversation to share your story, challenges, and goals. Dr. Ruiz will review your medical and psychiatric history and assess symptoms using a whole-person approach that considers biological, psychological, and social factors.

Together, you’ll develop a personalized plan that may include lab work, medication, and therapy. Initial visits last 60 minutes for thorough evaluation; follow-ups typically last 20–30 minutes, focusing on medication management and brief therapy. If needed, Dr. Ruiz can refer you to in-house or community therapists for add-on therapy support.  

Throughout your care, Dr. Ruiz prioritizes shared decision making to ensure you feel informed, empowered, and supported.
