Meghan T. Lee, Ph.D
Clinical Neuropsychologist and Practice Owner
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 visit my page and learn a little bit about me. To start, you can call me Meg, and I am what’s called a “Pediatric Neuropsychologist.” This means that I study the brains of children, teenagers, college students, and young working professionals. Said differently, I help kids 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 who are named Kiki (rag doll cat) and Dobby (chihuahua), as well as my friend’s dog Bruno (mastiff). 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.

Ramya Rangamannar, Psy.D
Clinical Neuropsychologist
Dr. Ramya Rangamannar earned her bachelor’s degree from Barnard College at Columbia University and her master's and doctorate degrees in Clinical Psychology from the University of Hartford. 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 adult and geriatric 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!

Meghan Lechuga, Psy.D
Clinical Neuropsychologist
Dr. Meghan Lechuga earned her doctoral degree with a concentration in neuropsychology from William James College.

She also has experience working with patients navigating the functional challenges associated with ADHD, learning disability, mood disorders, and complex medical conditions. She is dedicated to helping patients understand the causes of cognitive changes and providing patients with recommendations individually tailored to meet their needs. She is also interested in helping adults understand the normal cognitive changes expected across the lifespan and take action to preserve brain health throughout the aging process. Dr. Lechuga primarily sees adult and older adult patients.
Hi there! My name is Meghan, and you might see me around the office. I work mostly with adults, but I love chatting with kiddos too! I help people understand strengths and weaknesses in their thinking abilities.
Outside of the office, I love spending time outdoors with my family. You might catch me hiking up a mountain, skiing down a steep slope, running a trail, or cruising on my bike. You might even find me on a rock climbing wall! I love reading, baking bread, soaking up the sun, and chasing my toddler around on the playground!

Hi there! My name is Lexi and I am here to get to know you better. It is my job to help you better understand your thoughts, feelings, and behaviors. I enjoy working with kids of all ages to help figure out what you’re good at (strengths) and areas for growth (weaknesses). When we work together, we will do many different activities, such as drawing, playing games, answering questions about yourself, and puzzles to help us learn about your brain. I look forward to meeting you!
A little about myself: I grew up in Minnesota before moving to Colorado to finish school. I have lived here in Colorado for 6 years. When I am not working, I enjoy yoga, being outdoors, playing with my dog (Phoebe), and spending time with my family.

When I'm not at the Horizon office, I can be found spending time with my family and friends on outdoor adventures, snuggling with my dogs Ophelia (a chihuahua) and Ace (a rottweiler/bullmastiff mix) (quite different dogs, I know), taking horseback riding lessons, practicing music, and working out. I'm so excited to meet you!

Hiya, Pals! So very excited to get to know you! My first question for you will be “Who is your favorite Disney character?” So come prepared to tell me who and why! I am a big Disney fan! I worked at Walt Disney World for 8 years; or as they say out there “8 yEars.” Getting to work with amazing kids (like you!) is a big passion of mine, so you can count on me to be there for you and to bring a smile to your face.
When I’m not working, I love spending time with my cats, Jazz and Button. They are super snugly and rarely leave my lap (unless they see a laser pointer come out for play time).

Hi! My name is Bridget. I am a mother of two incredible children, wife to an amazing husband, and a proud Colorado native. I taught 2nd through 4th grade for 27 years and then decided it was time to retire from teaching and do something different. I have a positive, kind, and friendly personality and love helping others become their best.
When I am not working, you can find me reading, kayaking, gardening, going on long walks, swimming, volunteering in our community, attending my daughter's college events, or with my son on his Boy Scout adventures. My motto: "Strive to learn something new every day!"

Hello, my name is Markayla! If my name is too confusing, Kayla works as well! Right now, I am going to college to learn how to be a music producer—which is just a fancy name for someone that records music and helps the music artist figure out what they want their music to sound like. I am all ears if you want to talk about anything music related!
My job, here, at Horizon, is to sort and upload paperwork—so you'll probably see me around the office. When I am not at the office, I work as a stagehand, helping musicians set up and sound awesome during concerts. I also enjoy nature with my two dogs, Cookie and Lulu. Feel free to say "hi" anytime!

Hey, my name is McKenna! I am currently going to college and studying zoology (the study of animals). So, if you ever want to talk about animals, I am all in!
My job at Horizon is to help with the sorting and uploading of paperwork. You may not see me around the office that much.

If you do ever see me, feel free to come over and say "hi!"
