Katherine Billiot, Psy.D.


Board Certified in Biofeedback, Board Certified in Neurofeedback

"As a clinical psychologist at Medical Psychology Center, it is my goal to continue offering a thorough and pragmatic/results-driven approach in what I do.  I aim to provide a comfortable, safe, and professional environment for people to come to learn how to help themselves. This includes physical problems such as headaches and insomnia, cognitive difficulties like attention deficit and stroke recovery, and emotional problems such as anxiety, trauma, and panic attacks. I strive to help my patients make these difficult changes as simply and systematically as possible. We will revel in your accomplishments and learn from any setbacks, both of which are an inevitable and expected aspect of personal development and change. With an eclectic approach to clinical psychology, my therapeutic styles can range from dynamic to cognitive-behavioral, unique to each person and problem."

As a Florida licensed Psychologist, Dr. Billiot has specialized her training in neuropsychology, psychological evaluation, biofeedback, neurofeedback, RESET therapy, Eye Movement Desensitization and Reprocessing (EMDR), and hypnosis. She is Board Certified in Biofeedback and Neurofeedback and has been interested in the mind-brain-body connection since the early 1990’s. Dr. Billiot provides individual therapy, trauma resolution, and biofeedback/neurofeedback treatments to adults of all ages.  She also provides biofeedback/neurofeedback treatment to older children and adolescents and will consider this on an individual basis.

Dr. Billiot received her undergraduate training at Florida State University and a Masters of Arts in Psychology at the University of West Florida, Pensacola. An honors graduate of Florida Institute of Technology, Dr. Billiot was awarded a Doctorate of Psychology in 2002 and has over 14 years of experience in psychological evaluation and treatment.

Following graduation from FIT, Dr. Billiot moved to Yokosuka, Japan where she worked at the Navy Hospital as a Lieutenant. She served in the Mental Health Department prior to heading the Substance Abuse Rehabilitation Program which served the 7th Fleet and shore-based commands throughout Japan.

After being honorably discharged from service and receiving a Navy and Marine Corps Achievement Medal, Dr. Billiot returned to the Ormond Beach area to work with her father, Dr. George Lindenfeld, in his private practice of 20 years.  In 2006, Dr. Billiot founded the Medical Psychology Center, P.A. in the spirit of continuing Dr. Lindenfeld’s tradition of providing compassionate, professional, and effective treatment interventions and evaluation.

Dr. Billiot is currently studying physiology- and neurologically-based treatment interventions for emotional problems. These include EMDR, trauma RESET Therapy with BAUD, home practice with portable biofeedback devices,  biofeedback/neurofeedback for mindfulness, performance improvement, and panic attacks.  Her recent research study on the subject of Chronic Fatigue Syndrome and PTSD with RESET/BAUD was recently published and she continues to be amazed at this powerful treatment tool.

Lana Brown, MA, NCC, LMHC

"As a Licensed Mental Health counselor with specialized training, my therapeutic approach is optimistic, eclectic, and holistic. My goal is to use whatever techniques are appropriate for the client. I view mental health as part of the balance or imbalance of the individual, and I believe that a person's spiritual beliefs (with no bias) are easily integrated into the healing process. I am committed to a lifelong learning process and believe that as a mental health provider I can learn from each client I see, as well as from other professionals. I eagerly seek information about current counseling techniques and am willing to incorporate them with clients as they are applicable.  Some of my favorite approaches are hypnosis and relaxation therapy, cognitive-behavioral therapy, psychoeducation for empowerment, and positive thinking strategies."

Lana Brown is a nationally certified counselor and a Licensed Mental Health Counselor in the State of Florida. Lana began working with crisis and trauma clients over 30 years ago and has continued to develop specialty skills in treating the psychological aspects of trauma.  Lana is skilled in hypnosis and has pursued extensive training with the American Society of Clinical Hypnosis (ASCH).

Lana has worked in public mental health for several years and is comfortable working with persons who have chronic mental illness. Through professional and personal experience, she has more than 15 years of experience with patients and caregivers of those with traumatic brain injury. At the Medical Psychology Center, Lana has established herself as the resident dementia caregiver practitioner. She was a psychometrist at the Medical Psychology Center for a couple of years and has gained a comprehensive understanding of the psychological and neuropsychological instruments used by her colleagues.

Lana has individual and group experience with domestic violence offenders and survivors, sexual assault survivors, incarcerated persons, individuals with chronic mental illness, and caregivers.  She is skilled in providing couples therapy as well.  Depression and anxiety are present in the majority of these populations; much of Lana's experience has addressed these diagnoses.  Lana spent over a year in supervision with an internationally recognized specialist of dissociative disorders and has experience with the full spectrum thereof.
