Hi there and welcome!

My priority is supporting clients on their journeys towards personal healing & growth.

In 2010, I received my MSW/LMSW. While doing outpatient clinical work at the NYC non-profit agency JBFCS, I became an LCSW. In 2016, I began to establish my private psychotherapy practice, focusing on young and professional adults presenting with a broad variety of life challenges.

Hello! My name is Cathy Randolph and I am a Board-Certified Mental Health Nurse Practitioner. I developed my passion for mental health during my journey working with veterans in residential PTSD and Substance abuse programs. My specialties include, but are not limited to treating and managing PTSD, Substance abuse, ADD/ADHD, anxiety, depression, mood disorders, and adjustment disorder. I am also a Medicinal Marijuana clinician.

What if improving your relationships isn’t starting together, but starting with you? As a Marriage and Family Therapist (LMFT), I work with individuals who are curious about their relationship patterns and ready to create meaningful change from the inside out. You may feel stuck in recurring dynamics, find yourself questioning how your family background shapes your relationships, or want to communicate more effectively. Together, we create a space to gain clarity, better understand what’s driving these patterns, and begin making intentional shifts toward healthier, more balanced relationships.

Hi, I’m Chamin!

I bring over 25 years of experience to my work with individuals, couples, and groups, helping them move from feeling overwhelmed to truly empowered. My expertise has led to regular media contributions on platforms like The TODAY Show and CBS Sunday Morning, and I am the author of Seeking Soulmate: Ditch the Dating Game and Find Real Connection. I founded Chamin Ajjan Psychotherapy to provide a warm, welcoming, and supportive space where clinical excellence meets compassionate care and a little pop culture when I can throw it in. We are the regional clinic for the National Social Anxiety Center providing evidence-based treatment that upholds the rigorous standards of the organization. I am dedicated to helping you navigate life's challenges with a collaboration rooted in deep experience and practical, effective tools.

Our couples or relationship therapy framework is designed for partners seeking to rebuild intimacy, improve communication, and navigate life transitions. Please note: Our outpatient practice does not provide crisis intervention, court-mandated counseling, high-conflict mediation, or active separation/divorce litigation services.

I firmly believe it is never too late to seek help to live your best life. My name is Dr. Brittany Herbert. I am the sole founder and creator of Never-Too-late Solutions, a private psychotherapy practice that aims to meet all clients where they are and provide a safe and supportive environment. My practice is a client-centered, judgment-free zone where I aid clients in doing the work necessary to pull back layers, allowing us to explore feelings, thoughts, and behaviors.

I have a Ph.D. in Clinical Psychology and 22 years experience treating a range of difficulties with clients from all walks of life. I've narrowed my practice over the years to working strictly with adults and couples. While my postdoctoral work was focused on mood and anxiety issues, I have both training and experience with relationship issues, binge eating conditions, work/school stress, grief, and Ketamine Assisted Therapy (KAT).

As your mental health provider here's what I want you to know about me:

• I listen first
• I believe in collaboration
• I treat the whole person
• Medication is a tool, not a requirement.
• There is no shame in seeking help.
• Progress is possible.

I am a board-certified Psychiatric Mental Health Nurse Practitioner with over 14 years of nursing experience, caring for individuals from diverse backgrounds across healthcare and community settings.

My clinical background includes approximately one year working with men experiencing homelessness, where I conducted psychiatric evaluations to identify diagnosed and previously unrecognized mental health conditions that could affect employment, housing stability, and daily functioning. This experience strengthened my understanding of how mental health, life circumstances, and social challenges can impact overall well-being.

I also have extensive experience in postpartum and maternal health, giving me a unique understanding of perinatal and postpartum mental health concerns. While this remains a special area of interest, I provide psychiatric care to adults with a wide range of mental health needs, including depression, anxiety, mood disorders, ADHD, trauma-related concerns, and sleep difficulties.

At NurtureNest Behavioral Health, I provide comprehensive psychiatric evaluations, personalized medication management, and supportive therapy using a compassionate, evidence-based approach. My goal is to create a safe, judgment-free environment where you feel heard, understood, and supported as we work together toward greater emotional well-being and an improved quality of life.

Your mind and body are speaking—are you listening? As a board-certified Psychiatric Mental Health Nurse Practitioner with over a decade of experience in high-stakes intensive care, I understand what many overlook: mental and physical health are inseparable.

In critical care, I saw how stress, trauma, and anxiety manifest in the body—tight chests, sleepless nights, unexplained pain. And when the pandemic hit, I witnessed the silent emotional suffering of patients, families, and healthcare workers alike. That moment changed everything.

I chose psychiatry because healing your mind is just as vital as healing your body. If you’re feeling overwhelmed, exhausted, or like no one sees what you’re carrying—you don’t have to hold it alone. I’m here to help you reconnect, restore, and rise.
