Hi, my name is Jennifer and many people call me Jen. I am a Licensed Clinical Social Worker in NY and PA and have truly enjoyed my work for many years now. A little about me: I graduated from CUNY Lehman College in 2007 with an MSW.

I have worked in inpatient and outpatient settings, including a number of years in nursing homes and primary care.

I have worked with clients from a variety of backgrounds and age groups, helping them manage stress, depression, anxiety, relationships and medical difficulties. Most recently I have been working a great deal with adults with a variety of behavioral health and medical needs. I have worked in inpatient and outpatient settings, including a number of years in nursing homes and primary care. Having this variety of experience over the years has allowed me to build an understanding of effective ways to work with and support clients with varying needs.

First session

In our first session I will spend time gathering some history, getting know you and your values, and developing a treatment plan based on your goals. We will begin to dive into the specific challenges you are facing. We will finish our session by discussing timing and scheduling of sessions, and informed consent.

Strengths

With over 18 years of experience, my approach stands out by blending expertise with evidence-based practice. I prioritize goal-oriented treatment while maintaining a compassionate, collaborative and empowering space for my clients.

Ideal clients

I enjoy working with clients from many backgrounds and age groups, specifically helping them manage life stressors.

Origin story

I have a deep desire to help others navigate life's challenges and foster meaningful personal growth. I learned this many years ago when I was an intern and saw how creating a safe space and utilizing active listening helped people feel truly heard and supported.

Treatment methods

Cognitive Behavioral (CBT)

I use CBT techniques to help clients identify negative or anxious thoughts and learn how to reframe them, which helps reduce distress.

Mindfulness-Based Therapy

Mindfulness techniques such as deep breathing and grounding help us calm our bodies and mind.

Motivational Interviewing

Motivational Interviewing is a collaborative counseling technique designed to enhance motivation for change by exploring & resolving ambivalence.

Jennifer listened to my challenges and provided useful feedback to help me move forward. She is very genuine, not rigid, and easy to have a conversation with.
