Azia Berhe, PsyD, postdoctoral resident
Welcome! I'm Dr. Azia Berhe, and I’m glad you’re here. I hold a Master’s degree in Counseling and Psychological Services and a Doctorate in Psychology (Psy.D.) from Saint Mary’s University of Minnesota. I’m currently working toward full licensure in the state of Ohio, under the supervision of Dr. Jonathan Cleveland.
I work with adults of all ages, backgrounds, and life experiences—and I truly value the uniqueness that each person brings to therapy. I have a particular passion for supporting individuals from immigrant communities, as I understand how disorienting and complex it can be to adjust to life in a new country. Feeling seen and understood in those experiences can make all the difference.
My clinical background includes work in community mental health, outpatient clinics, and long-term care settings. I’ve had the privilege of helping individuals facing a wide range of challenges, including depression, anxiety, trauma, substance use, and cognitive concerns like dementia. I take a flexible, integrative approach to therapy—drawing from different therapeutic modalities to meet each client’s specific needs. What remains consistent, however, is my commitment to helping clients recognize their strengths, feel empowered, and move toward a life that feels meaningful and fulfilling to them.
I was drawn to this work because I’ve always found it natural to connect deeply with others and genuinely care about their well-being. Whether you're navigating a major life change, feeling stuck, or simply want a space to process your thoughts and emotions, I’m here to support you.
Outside of the therapy room, I enjoy traveling, trying new foods, relaxing with a good show, and spending time with friends and family.
If you're considering therapy, I look forward to the opportunity to work together.
Raquel Clark, PsyM, psychology assistant
Hello! My name is Raquel, and I moved to Ohio with a strong passion for education and mental health. I hold a master’s degree in clinical psychology from Wright State University, where I focused on forensic psychology and working with Spanish-speaking populations.
At Collective Within, I strive to create a supportive and inclusive therapeutic space where individuals from all walks of life feel welcome, heard, and empowered. I am deeply passionate about helping others become the best versions of themselves, and I approach therapy with an emphasis on positivity, personal growth, and resilience.
Outside the office, you’ll find me enjoying the outdoors with my dog, quilting, or curled up with a good book.

My name is Lillian Ferguson. I am a current second year graduate student at Wright State University’s School of Professional Psychology, earning my PsyD in clinical psychology.

I have a passion for working in this field, especially in the realm of trauma, and strive to make every person I interact with feel listened to, heard, seen, safe, and valued. I believe that with the right resources and care, every individual can tap into their resiliency and navigate this hard thing we call life with all the strength and power they are capable of. Regardless of what is brought to the table, I will be a support and the biggest advocate for your well-being.

Auden Blessing, administrative assistant
Hello, my name is Auden Blessing. I grew up in the Dayton area with three lovely sisters that have always been by my side and have helped me grow into who I am today. I attended Northmont High School and graduated in 2020. Before I started as a receptionist here at Collective Within, I worked for Target as a guest advocate for three years and as a barista at Warehouse 4 in Kettering. My prior work experience allows me to be well rounded when it comes to problem solving and showing up for someone in need.
I also enjoy pursuing creative endeavors. I love to produce music, sing, attend local music events, sketch, journal, and go hiking on cooler days. it’s important to have an outlet to express yourself, and for me, the arts are an amazing way to do that. :)
