“Leanna has simply been a breath of fresh air for me and I’ve really come to enjoy/look forward to our sessions. She’s kind and understanding and always actively listening - amazing qualities in a provider. She’s well-structured and gives me things to think about in between sessions and offers practical guidance and feedback. She’s created such a safe space for me, something I’ve always really needed. She’s been the best therapist I’ve ever had and I’m really looking forward to our future sessions - I actually believe that there’s personal growth and change on the other side of my journey having had her as my therapist thus far. She’s very attentive and asks really great questions - she’s awesome! I highly recommend her and her practice ”

Getting to know Leanna Lee-Sydnor
Hi, I'm Leanna Lee-Sydnor, founder of LLS Therapies, a boutique group practice supporting individuals, couples, and adolescents throughout New York and Connecticut.
You may be the person everyone depends on. The one who gets things done, keeps showing up, and rarely lets anyone see when you're struggling. From the outside, you look capable and composed. On the inside, you may feel overwhelmed, emotionally exhausted, disconnected, or unsure how much longer you can keep carrying everything on your own. Many of our clients live with a relentless inner critic, constant overthinking, or the feeling that they always have to get it right.
That's where we come in.
At LLS Therapies, we work with people navigating anxiety, burnout, relationship challenges, life transitions, and the emotional weight of always being the responsible one. Many of our clients are naturally private and have spent years solving problems on their own. They often don't need someone to tell them what to do, they need a space where they can think differently, soften rigid patterns, and understand themselves with greater clarity and compassion.
Our clinicians integrate psychodynamic therapy, CBT/DBT-informed skills, and attachment-based approaches to help you quiet the inner critic, improve emotional flexibility, strengthen relationships, and build lasting resilience.
Depending on your needs, you may work directly with me or with a thoughtfully matched clinician on our team. Our Zocdoc calendar reflects all current telehealth availability across New York and Connecticut, making it easy to find an appointment that fits your schedule.
What should a new client know about working with you?
At LLS Therapies, clients can expect sessions that are grounded, culturally responsive, and tailored to your goals. Our clinicians support teens, adults, and couples through a blend of insight, coping skills, and clear therapeutic structure. We create a space where you can be honest, slow down, and make meaningful changes that strengthen emotional regulation, connection, and long-term resilience.
What is your typical process for working with clients?
At LLS Therapies, we begin by understanding your needs and matching you with a clinician who fits your goals, personality, and preferences. Because we work with individuals, couples, adolescents, and college students, this step helps ensure you start in the right place.
Your first session is structured and grounding. We explore what’s been going on, identify patterns, and clarify what you want to change. Together, you and your therapist set a pace that feels both safe and productive.
From there, your clinician tailors the work to you; blending insight-oriented therapy with practical strategies. Our approach integrates psychodynamic work, CBT/DBT-informed tools, and attachment-focused exploration.
Most clients begin with weekly sessions to build momentum. Over time, sessions may shift depending on your needs.
Our goal is to offer a space where you can step out of performance mode, understand your patterns, and build lasting emotional clarity and stability.

Finding this therapist changed the trajectory of my life — I don't say that lightly. I came in carrying a lot: professionally high-functioning on the outside, running on fumes on the inside. What I didn't expect was someone who could meet me at both levels simultaneously — who understood that being capable and being okay are two very different things.
What sets Leanna apart isn't just skill, it's presence. She actually listens — not to diagnose or redirect, but to understand. Sessions never feel formulaic. She has a rare ability to reflect things back to you in a way that lands differently than you expected, and suddenly you're seeing your own patterns clearly for the first time.
She holds space without judgment, pushes when it matters and makes hard conversations feel safe. That balance is genuinely rare. If you're on the fence — this is your sign. Book the consultation. Do the work.

I was Leanna’s client for almost 5 years. She is the best therapist I’ve ever had and I’m very sad to leave her (I moved outside of her license area). From start to finish, she was caring, consistent and professional. She helped me process and manage anxiety, depression, and PTSD. For me, the safe, supportive space she provided during sessions was the key. She is an expert listener. She will validate when it’s appropriate, redirect unhealthy thoughts, and offer gentle accountability. Through it all, she helped me achieve a level of peace that I never thought was possible for me.
On the administrative side, she accepts insurance and her online portal makes paying for sessions very easy. Both the portal and Telehealth programs were very user friendly.
I highly recommend Leanna and her practice.

Leanna seemed to understand how I feel: Laughed with me when I was trying to be funny and was quiet and let me talk when I was serious. She's empathetic; I felt comfortable with her. I'll stick with her for the long run.

Working with Leanna has been awesome. I’ve been “in-therapy” off and on for a few years and I have never seen and felt a change in my life from therapy so quickly. The pre-session Q&A set the direction for the begin sessions; which I appreciated. Having an idea of what would be discussed took away some of the anxiety that came with seeing a new therapist. I leave my sessions with helpful suggestions and a sense of direction as to where I should start on my journey to improve.

Leanna demonstrates exceptional attentiveness, compassion, and professionalism throughout our sessions. She provides honest and constructive feedback while ensuring my feelings are acknowledged and validated. Rather than speaking down or minimizing my experiences, she skillfully guides me through processing and unpacking my thoughts in a supportive and respectful manner.
What sets her apart is her ability to connect through real-life experiences rather than relying solely on clinical terminology. Her approach feels genuine and relatable, making every session meaningful and personal. Working with her is not a check-box exercise—it’s a truly individualized experience tailored to my needs and growth. She consistently offers practical resources, such as reflective quizzes and vision board exercises, and always follows up to ensure continued progress.
I am deeply appreciative of her empathy, dedication, and the authentic care she brings to her practice.

The office was able to accommodate my work schedule, and I was seen relatively quickly after contacting them. Leanna is an amazing therapist! She took the time to understand my culture and background, and give empathetic feedback. She truly felt like a partner in my healing journey. I would highly recommend Leanna to anyone seeking to understand the root cause of their pain, and then build a collaborative plan to heal.
