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.

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.

Hey there! My name is Ben, and I am a neuropsycological technician. I recently moved here from California, so I am still getting used to what it is like to experience four seasons a year. Learning about the brain and helping people are a couple of my passions.

Like most people, I enjoy a good adventure! I like to go camping with my partner, go on walks with my cat, or get immersed in a good video game. Playing Dungeons and Dragons and reading adventure novels are some of my favorite things.

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). I also adore spending time with my family and surprising them in silly costumes just to make them giggle. Bringing happiness to people is my number one goal, and I am very excited to get to do that for you, too!

I can’t wait to meet you and learn about who you are! Here’s a little bit about me: I am from Colorado and love it here. I am a huge Denver Broncos fan and love to watch them play. At home, I have 2 cats, 2 dogs, and 3 ducks! Feel free to ask questions about any of them! I also love to cook and hang out with my friends and family. You can see all of them, as I always keep pictures at my desk.

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!
