Meet Our Doctors
Meghan T. Lee, Ph.D
Founder/CEO and Clinical Neuropsychologist
Dr. Meghan T. Lee earned her bachelor’s degree from Colorado State University and both her master’s and Ph.D. from Auburn University. She furthered her education in Neuropsychology through UC Berkeley Extension and Brigham Young University.
Hi everyone! Thank you for taking the time to read my bio and learn a little bit about me. To start, you can call me Meg, and I am what’s called a “Neuropsychologist.” This means that I study the brains of children, teenagers, college students, and adults. I help people understand how their brain works, what their strengths and weaknesses are (we all have them!), and how they can be the BEST version of themselves in life. Sounds pretty cool, right?
When I’m not learning about brains, I like spending time with my pets Dobby (Chihuahua), Finn (Great Dane), and Rylee (Great Dane). You’ll probably hear me talk about them a lot! I also love to travel, spend time with friends, and watch sports. As you can see, my husband (Matt) and I used to go to Red Sox games when we lived in Boston. However, since we both grew up in Colorado, we are definitely Rockies fans at heart.

She completed her pre-doctoral clinical internship at the University of Florida and post-doctoral fellowship in pediatric neuropsychology at the Children’s Hospital Colorado.
Over the last decade, Dr. Ramya has gained clinical expertise in a multitude of settings (i.e., medical, psychiatric, private practice) with children from early toddlerhood through early adulthood. Despite specialization in pediatrics, Dr. Ramya has also worked with younger and older adult populations in her training. She prides herself on understanding the "whole child" in the context of their home/family, school, and social realms and in providing families with tangible resources and recommendations in supporting their child’s development and success.
Hello! My name is Ramya, and I am looking forward to getting to know you. I work with kids of all ages. My job is to help others understand how you learn and think; so they can help you feel more successful and confident every day. A day with me will feel like a day at school (although I like to think it is a little more interesting because the day is all about YOU). I will get to know your brain through a number of different tasks such as questions, puzzles, writing, and drawing.
When I am not in the office, I love spending time with my friends and family. I am a Bollywood dance teacher and grew up learning all kinds of dance (ballet, tap, jazz, modern, hip-hop). I am pretty new to Colorado, but I love exploring it by hiking and camping. I would love to know if you have a favorite place you've visited in Colorado or if you have a favorite dance move to share!

Hey there! My name is Alison, and I am a neuropsychologist. This means I help people understand how their brains work. People also come to see me after they hit their heads playing sports, after a car accident, or even after slipping on ice!
Other than brains, sports are my favorite thing to talk about. I grew up figure skating and was also raised to be a big hockey and football fan (go Capitals and Seminoles!). Just like many of you, playing outside is important to me, and you can find me climbing up or skiing down mountains in my free time. I also love to run, do yoga, eat sushi, and listen to Taylor Swift. Looking forward to learning more about you and your favorite activities!

During her graduate career, she has worked with preschool-aged children in a school setting, and with adults and older adults in private psychological practice and outpatient medical settings providing therapeutic support and conducting psychological and neuropsychological evaluations. Her future career goal is to become a board-certified neuropsychologist focusing on assessment for traumatic brain injury and neurodegeneration populations. With her passion for neuropsychological assessment, Nicole is enthusiastic about completing her lifespan residency in clinical neuropsychology at Horizon Neuropsychological Services.
Hi! My name is Nicole, and I am very excited to meet you. Spending the day with me is similar to things you do in school. You’ll solve puzzles, answer questions, and tell me about things that are difficult for you. Our time together will help me learn about your strengths and things that you might struggle with. It’s my job to see how you learn best in order to provide you with tools to be successful and feel confident in yourself.
Here are a few things about me: I grew up in New Jersey and lived in California for a few years before moving here to Colorado. I really enjoy exercising, whether being in the gym or hiking, and I absolutely love traveling and exploring new places. I have two dogs and a cat that keep me entertained and I love spending time with family and friends having bonfires or just spending time outside soaking up the sun.
Spenser Nye, Psy.D
Clinical Neuropsychology Resident
Spenser Nye earned her bachelor’s degree from Kent State University and her master’s and doctorate degrees from the University of Denver. She completed her pre-doctoral internship at a Fort Collins, Colorado practice that focused primarily on neurodevelopmental, psychological, and neuropsychological assessments with individuals from across the lifespan.
During her graduate training, Spenser has trained across various settings, including emergency and outpatient medical settings, community mental health centers, and private practices. She has experience working with children, adolescents, and adults with a variety of neurodevelopmental disorders and neurological conditions, including autism, ADHD, FASD, and traumatic brain injury.

With her passion for pediatric neuropsychological assessment, Spenser is beyond excited to complete her residency in pediatric neuropsychology at Horizon Neuropsychological Services.
Hello! My name is Spenser, and I work with kids of all ages. My job is to figure out how the brain is working by asking clients to solve all kinds of different problems and puzzles. These activities will show me the things clients do really well, but it also shows me the things that are harder or take a little more time and effort. This information tells us the kinds of skills and supports a child will need (at school, home, etc.) to help their brain do the things it finds hard and reach their full potential.
When I am not in the office, I like to spend time with my family, friends, and dog named Lucy. On the weekends, I’m likely skiing, checking out a local farmer’s market, or playing fetch at the park with Lucy. I also love watching sports and am a huge fan of the Denver Nuggets! I am originally from Cleveland so also: go Cavs!
Kevin Ball-Duane, Psy.D
Clinical Neuropsychology Resident
Kevin Ball-Duane earned his bachelor's degree from Mercyhurst University and his master's and doctorate degrees from Widener University, specializing in neuropsychology, school psychology, and biofeedback. His pre-doctoral internship included rotations in adult forensic neuropsychology at a private practice near Philadelphia, PA, and pediatric neuropsychology at Good Shepherd Rehabilitation Hospital in Bethlehem, PA. He is also a certified school psychologist in Pennsylvania and board-certified in biofeedback.
Kevin's graduate training involved clinical experiences in private practices, schools, and an inpatient/outpatient medical center. He has evaluated individuals across the lifespan presenting with neurodevelopmental, medical, and psychological concerns. Kevin hopes to pursue board certification in neuropsychology, with a particular focus on helping individuals who have sustained a traumatic brain injury. With his passion for pediatric neuropsychological assessment, Kevin is 'psyched' to complete his pediatric clinical neuropsychology residency at Horizon Neuropsychological Services.
Hello, I'm Kevin! I look forward to getting to know you. My job is a little like being a detective for the brain, trying to understand how our brains work and how they affect how we think, feel, and behave. Spending the day with me involves some activities that may feel like school, while others are more like brain games or puzzles. Once we are all set, I will gather all the clues to figure out the types of things your brain finds easy, and then I will find some strategies to help you when things may be more challenging. We are all unique, and that is part of the mystery!
Here are some fun facts about me: I am originally from Buffalo, New York, where we tend to get a lot of snow. I am new to Colorado, but I have made many trips and always make some time for hiking! Outside the office, I enjoy playing games with family and friends, building LEGO, and watching movies or TV shows with our cat, Bandit.
Molly Sullan, Ph.D
Faculty Affiliate
Dr. Molly Sullan earned her doctorate degree in clinical psychology, with a specialization in neuropsychology, from the University of Florida. She completed her pre-doctoral internship and her two-year neuropsychology fellowship at the VA San Diego Healthcare System/University of California, San Diego.
Dr. Sullan’s research has focused on understanding the relationship between post-traumatic sleep difficulties and cognitive, psychological, and physiological recovery for patients with a history of acquired brain injury (e.g., traumatic brain injury and stroke). Clinically, she has experience in the assessment of a broad spectrum of neurological disorders both in inpatient and outpatient settings, including brain tumors, epilepsy and movement disorders (e.g., Parkinson’s disease), memory disorders and dementia, stroke and cerebrovascular disease, traumatic brain injury, demyelinating lesions, autoimmune disorders, complex psychiatric concerns, substance use disorders, and neurodevelopmental considerations.
Dr. Sullan is an affiliate faculty member at Horizon, which means that she does not currently see patients clinically. She works in research and remains involved with the HNS didactic series related to the HNS training program.
Hi! My name is Molly, and I am a neuropsychologist. I work in research, which means that I get to learn all about the brain and how it functions. A little about me—I was born and raised in Colorado, so when I am not in the office, I am usually outside doing all the fun things that this beautiful state has to offer: hiking, skiing, camping, and hanging out with my family, which includes my husband, daughter, and our two cats! I love to play soccer and am a huge fan of most Colorado sports teams (Go Broncos!). Since I went to the University of Florida, I will always be a Gator at heart as well!

I'm getting pretty close, too! This means that I want to help people understand how their brain works so they can feel successful and confident as they navigate life. I will mainly work with adults, but you might see me around the office. Feel free to say "hello!"
When I'm not studying or writing papers, I like to travel and spend time with my family, friends, and dog, Eros. I have lived in Colorado my entire life, so naturally, I love hiking, camping, paddleboarding, and doing all things outdoors except skiing. I have only ever gone once but am open to going more.
