Marian O'Brien-Frigo

Clinical Social Work/Therapist, LCSW

With over 14 years of clinical experience in an outpatient behavioral health setting, I have worked extensively providing treatment in Evidence-Based Therapies.
I am committed to helping my clients identify and reach their goals using a supportive, compassionate, strengths based, direct approach. Reach out today to start feeling better. I look forward to working with you.

Dr. Leah O'Reilly


Dr. O’Reilly works with children 5 and older, adolescents, and adults in individual therapy. She also conducts psychological assessment/evaluations (personality, cognitive, and more). The primary issues she works with include mood disorders (anxiety, depression, etc.), behavioral issues, interpersonal issues, family life, and LGBTQIA+ affirming therapy.

Tina Brigham LCSW, SAC


Tina strives to create a warm, comfortable, and trusting environment. It is important to her to tailor therapy to individual needs. She utilizes collaboration, teamwork, the mind-body connection, and strength-based approaches to foster an environment of empowerment, understanding, and authenticity. She typically combines talk therapy with psychoeducation in order to help clients process experiences, build skills, and gain insight. Tina finds value in looking at the symptoms, rather than the generalized diagnosis, and is skilled at “digging deep” to help understand patterns of behavior, thoughts, and belief systems. She also has a passion for identity exploration work and assisting patients in pursuing their authentic self.  Tina adheres to trauma-informed care, diversity competency, and is a LGBTQA+ ally. She is confident that her unique approach to therapy, combined with her skill set, can be a good match for you.

Dr. Abigail Ream

Psychologist, PsyD

Welcome to our site! I provide adult patients with individual therapy specializing in the areas of trauma, loss, transitions in life, relationship difficulties, clarification of life goals, and self-esteem. I will work to assist you in identifying your own strengths and how to nurture and harness these strengths to meet your unique goals for therapy and life. You have a wealth of knowledge about what works and what does not work- I’m here to help organize this information in a useful way and help you fill in the blanks or help problem solve areas where you might be stuck. I’m ready when you are.

Dr. Joanna Love

Psychologist, PhD

I understand that assessment is an ongoing and collaborative process. I share the knowledge I have gained through my education and experience, so clients understand what informs my practice. I am very transparent with my perspectives, so clients shouldn’t have to wonder what I am thinking. I am far more interested in understanding the unique individual rather than focusing primarily on the specific diagnosis or problem.

Dr. Heidi Heimler

Psychologist, PsyD

Recent or remote trauma may be limiting you socially, professionally and/or interpersonally. If you’re struggling with emotional symptoms, I’m here to help. I offer evidence-based psychotherapy to assist you in regaining a sense of balance and wellbeing. Whatever your struggle, I am here to listen, to provide support and psychotherapeutic treatment tailored to meet your unique emotional needs.

She has 10+ years of experience working in a variety of behavioral health settings, and she has worked in every level of care (i.e., inpatient, residential, partial, intensive outpatient, and outpatient).

Dr. Lori Garfinkel

Clinical Psychologist, Licensed Professional Counselor

Dr. Garfinkel works to holistically create a warm, supportive, and judgment-free space for the person to include all aspects of their lives to help them reflect on their struggles and draw on their personal strengths to bring about change. She believes that most people have the tools within themselves to make meaningful progress in therapy and, for most, problems in living can effectively be resolved through an outsider’s perspective and by drawing from the person’s inner perspective on their experiences.

Dr. Kavitha Venkateswaran


When we are enduring personal struggles, oftentimes we are searching for a sense of understanding within our relationships. Dr. Venkateswaran takes an interpersonally-rooted, culturally-informed approach to therapy in an effort to help you feel deeply understood and to honor your identity and life experiences, as we work collaboratively to reach your goals. She has over 10 years of experience practicing within university counseling centers, hospital settings, VA medical centers, and community clinics. She has expertise working with women’s health issues and Veterans and also has experience working with a wide array of issues, including depression, anxiety, trauma, life transitions/stressors, relationship issues, perinatal mental health, sleep concerns, chronic pain, and race-based stress. Dr. Venkateswaran is also certified in Cognitive Processing Therapy for the treatment of PTSD.

While all of our Milwaukee therapists share a common goal, providing premium care in a safe environment, we know that therapy is not a one size fits all process.

This allows us to ensure that our patients get specialized care in a comfortable setting, whether that is in-person at our Milwaukee office or via Telehealth appointments.
