Meet our psychologists, counselors, and therapists.

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. Sarah Hoerl

Psychologist, PsyD & Divorce Mediator

Dr. Hoerl works with adults, adolescents, and children, and primarily offers individual and couples therapy. She also offers divorce mediation. She has experience working with anxiety, depression, relationship problems, grief, interpersonal difficulties, behavioral problems, and trauma reactions.  In addition, Dr. Hoerl works with women experiencing difficulties with pregnancy and postpartum experiences.

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.

Dr. David Radovich


Dr. Radovich is a Wisconsin licensed psychologist with 20 years of service in the field.  He has worked in outpatient settings, crisis services, prisons, teaching, and has a history of working with community support programs.  He provides excellent care and solution-oriented goals to address patients’ needs.  He puts forth his best effort to create a safe and welcoming place for everyone that comes in so that they can get the most out of the therapeutic experience. 


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.

Brian Michael Flynn, MSW, LCSW, CPIC


Brian is a warm, compassionate and present Clinical psychotherapist with over 20+ years of experience working with adults and families in a variety of clinical and community settings. He uses a client centered approach to understanding the whole person, and partners with his clients as they take an active role in their own healing and growth. His clients will engage in a nonjudgmental, collaborative and creative process to help them see their own strengths and to identify thought processes that are counterproductive to their wellbeing and relationships. His goal is to help each client accomplish their goals in the most useful and realistic manner. He believes that when people take an active role in their process of change, it is a very challenging and courageous experience, and he is respectful of this process for people.
