A message from Nicole: 

"As a licensed therapist my job is to empower you to reach your greatest potential and meet your goals. Each person has a unique set of needs, strengths, and goals that they want to accomplish. In our work together, I will serve as a guide for you to discover a deeper understanding of yourself, your emotions, thoughts, and behaviors. The journey of therapy can result in many things for many people, some of those things being improved relationships, increased self-esteem, enhanced ability to cope with life stressors, and greater happiness and life satisfaction.

Each therapists’ approach to counseling is distinct and it’s important that you work with a professional whose style “fits” with your personality and needs. I integrate several counseling approaches in my practice, including cognitive behavioral therapy, dialectical behavioral therapy, mindfulness, and person-centered and strengths-based approaches."

Robert earned his Masters in Education degree in Counseling and Human Services from Lehigh University in 2023. He is currently practicing therapy as a pre-licensed professional. 


Robert uses an integrated style of counseling focusing on methods from Rational Emotive Behavior Therapy (RBT) and Internal Family Systems (IFS). This means he offers a safe and non-judgmental space where you can explore the content of your thoughts and emotions, and how they influence your behavior and overall well-being. IFS also teaches that we are divided into different “parts” that can be in conflict with each other and prevent wholeness. 


Robert’s therapy practice focuses primarily on anxiety, depression, relationship/attachment struggles, alternative sexualities, and helping those who are neurodivergent. He currently sees individuals and groups. He is also bilingual and able to see Spanish-speaking clients as well. “Él es bilingüe y puede ver a clientes hispanohablantes”.

Anna treats each person as a unique individual and tailors therapy to meet each person’s specific and sometimes changing needs. She takes an integrative and trauma-informed approach and makes use of psychodynamic, psychoanalytic, CBT, and narrative approaches, as well as mindfulness and nutritional psychiatry. 


Anna focuses on working with individuals with relationship issues, trauma, depression, grief, and anxiety, as well as those with personality disorders.
