Lyle is a nationally certified Physician Assistant specializing in psychiatry, with a clinical focus on mood and anxiety disorders, ADHD, bipolar disorder, and PTSD.

Lyle graduated with a Master of Science in Physician Assistant Studies from South University, where he earned a 4.0 GPA and high honors distinction. He received his undergraduate degree magna cum laude from the University of Georgia with a Bachelor of Science in Health Promotion from the College of Public Health. A lifelong scholar and recipient of several academic accolades—including the Georgia Governor’s Scholar and UGA Charter Scholar—Lyle has also contributed to the Physician Assistant National Certification Exam Forms Review in 2019.

Lyle has nearly a decade of experience providing high-quality, patient-centered care to adults and adolescents. He strives to build trustworthy, supportive relationships with patients and simplifies complex psychiatric concepts so individuals feel informed and empowered in their care. Lyle tailors his approach to each patient’s unique needs, experiences, and goals, focusing on treating the whole person with attentiveness, integrity, and genuine care.

Outside of the office, Lyle finds joy in gardening, cheering on the Georgia Bulldogs (“Go Dawgs!”), and staying active through sports. He also enjoys spending quality time with his family and two beloved dogs: Buster, his 15-year-old rescue pup, and Tux, a playful Bernedoodle.

 

We’re proud to share that our three affiliated practices—Psych Atlanta, Georgia Psychiatry & Sleep, and Roots Behavioral Health—are now part of the Hightop Health family. While each clinic has built its own legacy of trusted care, we’re taking the next step forward—bringing everything together under the Hightop Health name.

This change is part of our commitment to creating a premier, clinician-led outpatient mental health group that sets a new standard for comprehensive, compassionate care. Though the brand is evolving, nothing about your experience is: same expert teams, same innovative treatments, same personalized approach. Now unified by a single mission—to deliver better mental health care that inspires hope and lasting healing.

This transition won’t affect your care—but it will enhance the way we show up, work together, and serve communities across Georgia, Texas, and beyond.
