Dr. Colin Brietzke
Licensed Clinical Psychologist
Clinical Neuropsychologist
Jacy Holmes, PsyD
Licensed Clinical Psychologist
Clinical Neuropsychologist
Hi! My name is Dr. Jacy Holmes. I am a licensed clinical psychologist and clinical neuropsychologist, having completed a formal two-year post-doctoral fellowship in neuropsychology. My passion lies in providing comprehensive assessments for individuals with brain injuries, neurodegenerative diseases, neurodevelopmental disabilities and various psychiatric disorders, such as schizophrenia, bipolar disorder, and personality disturbances. My doctorate was obtained from a university committed to social justice, which deeply influences my advocacy for marginalized communities, something I actively engage in during my free time.
With diverse experience across nursing homes, inpatient facilities, community mental health, and private practice, I’ve built a robust understanding of this field. Initially focused solely on delivering accurate diagnoses, I’ve since developed a deep appreciation for the stories behind my client’s journeys. It’s a privilege to offer my clients answers that guide them toward a better quality of life. My approach is collaborative; you are the expert on your experiences, and I bring my knowledge, background, and research to our partnership to provide best possible recommendations. Known for my warm and humorous demeanor, I strive to make you feel comfortable and heard throughout the process.
In addition to neuropsychological and psychological testing, I also conduct forensic assessments including evaluations for fitness to stand trial, insanity defenses, and risk assessments. This work has honed my skills and ensured my assessments are evidence-based and accurate.
Outside the office, I enjoy spending time with my wife and daughter, typically debating our next tv show or movie to watch. I also enjoy exploring Chicago’s food scene. I am constantly learning about myself and I’m eager to learn more about you.
Thank you for taking the time to read about me. If you think we’d work well together, I look forward to meeting with you.
Tobin Ehrlich, PhD, ABPP-CN
Board Certified in Clinical Neuropsychology
Licensed Clinical Psychologist
Hi, my name is Dr. Tobin Ehrlich. I’m a Licensed Clinical Psychologist with advanced training in Clinical Neuropsychology. I have trained and worked in a variety of settings providing comprehensive neuropsychological, psychological, and psychodiagnostics assessment services for individuals with diverse needs. I have served those who are navigating various neurological and/or mental health disorders, in addition to those navigating the intersection of the two. I am passionate about understanding brain-behavior relationships and translating that knowledge to help provide clarity to individuals and their families.
Outside of work, I enjoy live music, reading, meditation, outdoor activities, and exploring the vast world of tea.
Brendan Hendrick, PhD (He / Him)
Licensed Clinical Psychologist
“The world needs all types of minds.”
― Temple Grandin
My name is Dr. Brendan Hendrick, and I am so glad to meet your magnificent mind! Trying to understand what makes your mind unique is no small task-maybe you want to know how to deepen your relationships, or you’re curious why some things are so hard to learn. Maybe you need a roadmap for understanding what strengths or weaknesses are unique to your brain. Or, maybe you are stuck-trying to figure out what kind of mental health care will fit your mind. As a clinician and diagnostician, I can help answer those questions, and many more.
My work focuses on assessment and evaluation and I bring my values of mental health inclusivity, care, and whole-person understanding to every client and family. I specialize in evaluation to support school-age children, especially those who may need coordination with school supports, and I have extensive training in autism spectrum disorder. I believe strongly in the limits of any one “label” or diagnosis, and will work to advocate across stakeholders for the best outcomes for you.
My own journey was anything but typical. I completed an M.A. in elementary teaching from National-Louis University after I finished by B.F.A. in Theatre Design from Illinois Wesleyan University. Then I followed my curiosity to a School Psychology PhD from UNC Chapel Hill. When I wasn’t rooting for the Tarheels, I was falling in love with cycling. Now that I’m back in Chicagoland, I spend my free time looking for the next great restaurant to bike to or movie to see. I love hosting dinners, supporting local theatre, and traveling with my wife, Noel, in search of the world’s best pizza!
I really appreciate you taking a moment to read about me, and I am sincerely looking forward to meeting you and your magnificent mind!
Aubrye Brower, PsyD
Licensed Clinical Psychologist
I am Dr. Aubrye Brower, a licensed neuropsychologist who completed a two-year APA-accredited postdoctoral fellowship in Neuropsychology. Over the last few years I have worked across a variety of clinical settings including hospitals, inpatient and outpatient clinics, nursing facilities, and private practice settings, providing comprehensive psychological and neuropsychological services to adolescents, adults, and older adults.
My current practice focuses on comprehensive psychological and neuropsychological evaluations with expertise in ADHD, learning disabilities, mood and anxiety disorders, traumatic brain injury (TBI), stroke, dementia, and concerns related to aging and cognitive functioning. I am passionate about helping individuals gain clarity and understanding during times of uncertainty. I strive to create a warm, supportive, and collaborative environment where patients feel heard and understood as they share their experiences and concerns. I provide diagnostic clarity and thoughtful recommendations tailored to each individual’s unique cognitive, emotional, and functional needs. I am dedicated to helping patients and families better understand themselves and move forward with greater confidence and direction.
Outside of work, I enjoy exercising, hiking while visiting family in North Carolina, and exploring local coffee shops.
Kenneth Vicencio, PsyD
Licensed Clinical Psychologist
Pediatric Neuropsychologist
Hi! I’m Dr. Kenneth Vicencio. When children struggle at school, at home, or with friends despite consistent support, it often signals a deeper underlying challenge. Parents frequently feel frustrated knowing something is getting in the way, yet lacking the clarity to address it effectively. I specialize in helping school-aged children and adolescents find clarity when things feel confusing or overwhelming, focusing on challenges like ADHD, Autism, learning disabilities, and the cognitive effects of medical conditions such as TBI, epilepsy, and other neurological health challenges.
I look at how your child functions in the real world, translating complex brain-behavior findings into practical plans. Whether it’s securing the right school supports, understanding a medical diagnosis, or finding a new way to connect with your child, I work with you to bridge the gap between clinical data and daily life.
I believe the best results come from partnership, focusing on strengths as much as struggles. It’s easy to get lost in what a child can’t do, so my goal is to uncover what they can do brilliantly. You know your child better than anyone else, and my role is to bring my clinical lens to your insights, creating a collaborative process where your child feels heard, understood, and safe. I strive to make the evaluation process itself a positive experience, building a roadmap that feels achievable and fosters confidence rather than just providing a label.
When I step away from clinical work, I enjoy exploring new cuisines, tackling home improvement projects, and spending active, creative weekends with my family. I’m also an enthusiast of visual animation. Every child’s brain works differently, and I am committed to learning how your child specifically thinks and learns. I would welcome the opportunity to meet you and create a clear plan for your child’s future.
Kayleigh Slater, M.Ed, Ed.S
Psychometrist
Hi, my name is Kayleigh Slater, and I’m a psychometrist at Chicagoland Neuropsychology. In my role, I administer neuropsychological assessments to patients.
Before joining this team, I worked as a school psychologist, where I had the opportunity to support students in both urban and rural school settings. I’ve worked with students from pre-kindergarten through twelfth grade, which gave me a strong foundation in assessment. I have experience administering and interpreting a wide variety of cognitive and academic tests, as well as behavioral, emotional, and executive functioning rating scales.
Outside of work, I enjoy reading, gardening, and boating with my family. A fun fact about me is that I’m scuba certified!
Gabriel Nkemeh, MHSc
Psychometrist
Hi, my name is Gabriel Nkemeh, and I’m a Psychometrist at Chicagoland Neuropsychology. In my role, I work with patients and clinicians to administer, score, and help interpret psychological and neuropsychological assessments.
I believe that creating a welcoming, supportive environment where patients feel truly heard and understood is fundamental to effective assessment. Throughout my clinical training and work across diverse healthcare settings, from urban medical centers to international health systems, I’ve seen firsthand how taking time to listen empathically, communicate clearly, and offer compassionate care can make all the difference to patients.
I’m particularly passionate about mental health and working with individuals from varied backgrounds, ensuring that everyone receives culturally-sensitive care tailored to their unique needs. My clinical interests center on understanding how psychological and neuropsychological assessments can provide powerful insights into a person’s cognitive strengths and challenges. Overall, I’m dedicated to being a supportive partner in each patient’s journey toward deeper self-understanding.
Outside of work, I love working with my hands and tinkering with projects. I’m also a movie enthusiast, always on the hunt for hidden gem restaurants, passionate about seeing the world through travel, and making new memories with friends and family.
Ally Matson, MA
Psychometrist
Hi, my name is Ally Matson, and I’m a Psychometrist at Chicagoland Neuropsychology. In my role, I administer neuropsychological assessments and work closely with patients and clinicians throughout the evaluation process.
Originally from the Chicago area, I moved to Boston to earn my bachelor’s degree in Psychology, followed by a master’s degree in Child Study and Human Development with a concentration in Clinical Developmental Health and Psychology. Throughout my education and training, I had the opportunity to work in a variety of educational, clinical, and research settings, including the Cognitive Neurology Unit at BIDMC, Museum of Science, McLean Hospital, the Tufts Memory and Cognition Lab, and the Tufts Interdisciplinary Evaluation Research (TIER) Lab.
During graduate school, I discovered my passion for psychometry and the unique role neuropsychological assessment plays in helping individuals better understand their cognitive, academic, and emotional strengths and challenges. I enjoy creating a welcoming, supportive environment where patients feel comfortable throughout the assessment process, and I value being part of a team that helps individuals and families gain clarity and direction.
Outside of work, I enjoy drawing, reading, playing board games, thrifting (especially, vintage art and postcards), and taking care of my ever-growing collection of houseplants. In the future, I hope to pursue a doctorate in School Psychology so I can continue supporting children, adolescents, and their families through assessment and intervention.
Hildie B. Ericksen, LCPC
Licensed Clinical Professional Counselor
I am Hildie Ericksen, a Licensed Clinical Professional Counselor (LCPC) with a Master of Arts in Counseling Psychology from North Park University, where I graduated in 2018. I also hold certification in ADHD therapy. With experience working with individuals across the lifespan, I am dedicated to empowering individuals through personalized and effective therapy to meet your needs.
My approach is grounded in person-centered therapy, which fosters a strong therapeutic alliance, creating a supportive environment where clients feel valued and understood, thus facilitating meaningful self-exploration and personal growth. I incorporate other evidence-based practices, including Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT). Whether you are managing mood concerns, building executive functioning skills, working through personal challenges, or seeking to improve your emotional well-being, I am committed to guiding you towards a more balanced and fulfilling life.

Lisa Buckley
Licensed Clinical Social Worker
My name is Lisa Buckley and I am a licensed clinical social worker with over 25 years of experience working with children, adolescents and families. Having worked as a clinician within schools, I offer a unique perspective to supporting children and adolescents as they navigate the changes and challenges of life.
I believe that when people feel heard and are able to share their story without fear of judgment, lasting change begins. Relationships that are built on trust and acceptance are the cornerstones of the therapeutic process. By integrating relationships with a variety of treatment modalities and evidence based techniques, including cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and solution focused therapy, I am able to customize support for those who are experiencing challenges with depression, anxiety, autism, ADHD, interpersonal conflict, low self-esteem, trauma and grief. I am also able to provide support to families who are wanting to improve communication, manage conflicts, and build stronger relationships.
Ultimately, I believe the therapeutic process ought be a positive and collaborative experience in which people feel safe, respected, and empowered to explore improved mental and emotional well-being. Together, with authenticity, compassion, and humor, we will navigate an individualized plan of care to achieve your treatment goals.
When I am not at Chicagoland Neuropsychology, I provide school social work services in the near north suburbs. In my free time, I enjoy spending time taking nature walks with my dog, listening to books and podcasts, and laughing with my family.
If you think I could be the right therapist for you, I invite you to contact me to schedule a consultation.
Jennie Weng, PEL
Therapeutic Learning Specialist
Hi, my name is Jennie Weng and I’m the Therapeutic Learning Specialist at Chicagoland Neuropsychology. I’m a dedicated educator and licensed teacher who believes every student can thrive when they feel seen, supported, and understood.
I take a thoughtful, individualized approach with each student and work to create a safe, supportive space where they feel comfortable asking questions, making mistakes, and building confidence in their abilities. I combine academic support with social-emotional guidance and executive functioning strategies to help students develop organization, self-awareness, and effective learning habits.
I also believe strong partnerships with families are essential. I work closely with parents to understand each child’s strengths, challenges, and goals so we can create a plan that supports their success both academically and personally.
At Chicagoland Neuropsychology, I meet with parents to develop personalized learning plans and work directly with students during tutoring sessions.
Outside of the office, I enjoy spending time with my husband and our cats, playing Nintendo Switch with my younger brothers, listening to live music, traveling to new places, and trying great food.
Marzena Kukulak, CPB
Office Manager
I have over 10 years of experience in Healthcare Administration and Revenue Cycle Management. I focus on keeping the practice running smoothly and efficiently, ensuring that both patients and providers have a seamless experience from start to finish.
I thrive on the challenge of resolving billing issues and find satisfaction in knowing that I’ve made a difference in helping patients navigate what can often be an overwhelming process. Knowing that I’ve helped improve the overall patient experience is incredibly rewarding. While it’s one of those behind-the-scenes tasks that doesn’t always get noticed, it makes a significant difference in how patients perceive their care.
Fluent in Polish, I am always ready to connect and provide support in both Polish and English.
Outside of the office, I enjoy working out, spending time with my family through outdoor activities, teaching my children how to cook, and exploring new travel destinations.
