Stephanie Vaughn, Psy.D.
& Clinical Director

DBT-Linehan Board Of Certification, Certified Clinician™

As the owner and Clinical Director of PSYCHē, PLLC, in Nashville, Tennessee and now, Boston, Dr. Vaughn believes that healthcare industry, particularly the mental health care industry, needs to raise the bar. She believes in doing treatment the way it is supposed to be done and in truly listening. She knows that there is no substitute for doing “the basics” right. She believes in getting notes done on time, collecting records to better understand your case, educating herself regularly, and in providing actual help, not just an ear.

No one wants to take advice from someone who can’t manage their own life

Sarah Fink, M.Ed., Ed.S.

Sarah is known for unprecedented responsiveness and a warm and inviting smile. She is easy to talk to, but also gets “real” when need be. She has worked with kids, adolescents, adults, and families for over 5 years providing home-based therapy and parent coaching, working with families with a child diagnosed with Oppositional Defiant Disorder (ODD) or Attention Deficit/Hyperactivity Disorder (ADHD), and has experience with the early identification of Autism Spectrum Disorder. She has honed her basic skills treating depression and anxiety, but also enjoys helping people through life-transitions (aka, “girl, *^%# that job!”) and working out issues you may or may not have with your mother-in-law.

Sarah completed her undergraduate degree at Georgia State University, received her Master's of Education in Clinical Mental Health Counseling at Clemson University, and is a Mental Health Counselor under supervision with her license pending in Massachusetts.

Along with her background in mental health and psychology, Sarah has also completed a cosmetology program, which further informs her passion for self-care, attention to detail, and the pride and satisfaction that comes with taking care of yourself physically, as well as emotionally. Sarah knows taking the first step to find a therapist isn't easy and doesn't take that show of strength lightly, or the fact that you chose her for granted! 

When she's not in the PSYCHē office, Sarah thoroughly enjoys spending time with her family and friends, traveling to new places, finding new podcasts, cooking, and trying to convince her boyfriend they need a Golden Retriever puppy. Sarah also loves coffee, dark chocolate, any kind of baby animal, home decorating, and visiting any kind of body of water, big or small.
