Adisa Ptah M.S, BCBA
Behavior Analyst
As a Behavior Analyst, I find immense satisfaction in the daily opportunity to make a positive impact on the lives of individuals and their families. What I enjoy most about my job is the chance to use evidence-based strategies to assess and understand behavior, ultimately helping individuals achieve their goals and improve their quality of life. It’s incredibly fulfilling to witness the progress and growth of the clients I work with, and I appreciate the collaborative nature of ABA, where I get to work closely with families and interdisciplinary teams to tailor interventions that are both effective and compassionate. The constant learning and adaptability required in this field keep me engaged and motivated, ensuring that each day brings new challenges and opportunities for growth.
I have a passion for photography, revel in the beauty of hiking through nature, and thrive on exploring new destinations through travel.

I am a Behavior Analyst at Atlas and been in the field of ABA since 2016. I began as a behavior technician for a clinic in Dallas, TX, moved to California to pursue an education in Applied Behavior Analysis at California State University at Northridge, and joined Atlas in 2020. A fun fact: I was born in Asuncion, Paraguay and moved to America when I was 6. I hope to visit and see how much things have changed!
Coral Florian M.S,
Program Supervisor
I currently serve as a Program Supervisor at Atlas Behavior Services. I earned my BA in Psychology and MS in Applied Behavior Analysis from California State University, Northridge (CSUN). During my academic journey, I gained valuable practicum experience as a student at CSUN and contribute as a research assistant at KLab Behavior Science & Technology Lab. My career in this field began as a behavior technician and intern at Atlas Behavior Services where I provided one-on-one services to our clients. Outside of work l find joy in immersing myself in nature, photography, creating new experiences, and despite my admitted lack of culinary experience, I excel as a wonderful sous chef.
One of the most rewarding aspects of my role is witnessing our clients’ progress and hearing parents’ excitement about how their child applies what they’ve learned in their daily lives. I also enjoy working with parents and providing them with support and guidance.

Monica Montalvo M.S, BCBA
Behavior Analyst
I studied at the University of California, Irvine where I earned my bachelor’s in psychology and social behavior in 2016. After working as a behavior technician for 6 years, I furthered my education at California State University of Northridge to attain a Master of Science in Applied Behavior Analysis in 2021. After graduating, I received my BCBA certification and have been practicing as a program supervisor at Atlas Behavior Services for the past 2 years. Seeing my clients make their little and big successes from session to session is a rewarding experience and allows me to go home with something to look forward to every day. In addition, seeing parents and other family members gain confidence in participating and implementing treatment plans that help their child and family dynamic adds to the fulfillment I feel walking into and out of sessions. Lastly, a big part of my job that I truly enjoy is getting to mentor and train my behavior technicians because without them, improvement of my clients would not be possible. Fun fact, I paint canvases of all sizes at home and work part time at an art studio making sculptures.
