Maria P. Hanzlik, PsyD, HSPP, Licensed Psychologist

Dr. Hanzlik is a clinical psychologist and an AASECT-certified sex therapist who works with children, adolescents, and adults to provide psychological evaluation services and individual, couples, and family therapy serving the Indianapolis area. She received her Bachelor of Arts degree from The University of Delaware followed by her Master and Doctorate degrees in Clinical Psychology from The Chicago School of Professional Psychology, Chicago Campus. She has trained and worked in a variety of clinical settings including an inpatient psychiatric hospital, a college counseling center, and community mental health centers. She worked in group private practice for several years before opening her own private practice in 2015. In order to better serve the needs of the community, Dr. Hanzlik transitioned from independent practice to group practice in 2018, and renamed the practice Integrated Psychological Center of Indiana (IPCI). 

Dr. Hanzlik was trained as a generalist to treat a variety of mental health concerns, including depression, anxiety, and behavioral issues, for individuals across the lifespan (children, adolescents, adults, and older adults). She was also trained in providing therapy for individuals, couples, and families. 

One aspect that makes Dr. Hanzlik is unique is having obtained additional post-graduate training in sexual concerns, and she is one of the few AASECT-certified sex therapists in the Indianapolis area, as well as across the state of Indiana. In addition to treating sexual concerns, her other areas of expertise include trauma work (including approaching trauma treatment from a tri-phasic model and the use of EMDR, (Eye-Movement, Desensitization, and Reprocessing), couples therapy, and psychological assessment/evaluation. Please refer to the Services Provided tab for more information. 

Dr. Hanzlik is trained in a number of theoretical and applied therapeutic orientations including psychodynamic, cognitive-behavioral, humanistic-existential, family systems, emotionally-focused couples therapy, and Gottman couples therapy work. Her therapeutic approach includes creating a safe, accepting, and collaborative therapeutic space to allow the healing process to occur freely. After therapeutic goals are set, she balances utilizing practical, applied tools with exploration of factors that fuel or underlie presenting symptoms. This approach facilitates immediate symptom relief while working on long-lasting change. 

In addition to providing therapy and psychological evaluation (testing) services, Dr. Hanzlik frequently presents to general audiences, as well as at regional conferences, training centers, medical schools, and graduate schools, to provide continuing education and training speaking on the topics of incorporating sexual health into psychological and medical practice, trauma-informed care, and effective parenting practice. Dr. Hanzlik is also available for media interviews on any of her areas of expertise.

Josie Gronbach, PsyD, Post-Doctoral Clinician 

Dr. Gronbach earned a Bachelor of Arts degree in Psychology at Concordia University, St. Paul as well as both Master of Arts (MA) and Doctor of Psychology (PsyD) degrees in Clinical Psychology at the Minnesota School of Professional Psychology. Dr. Gronbach has had a variety of clinical training experiences ranging from community mental health and private practice settings, university counseling centers, and a large outpatient center providing intensive outpatient group services for adolescents and adults.

Dr. Gronbach works with adults seeking both individual and couples therapy and conducts psychological evaluations for children, adolescents, and adults. She treats many presenting concerns including anxiety, depression, trauma, relationship issues, grief/loss, sexual concerns, and family of origin concerns.

Dr. Gronbach is a great fit for clients who are curious about why they are suffering, so that they can identify and resolve the underlying causes of their symptoms. In session you will address the questions, “How can I immediately treat my symptoms?” but also, “Why are they presenting in the first place?” and "How can I resolve these underlying issues?" Dr. Gronbach cares deeply about creating a strong therapeutic relationship, and works to best understand and treat each person from a multifaceted, depth approach. She builds a trusting, safe, and compassionate space for each person to explore all aspects of their story on their journey to finding greater peace, healing, and contentment. She pulls from emotion-focused, psychodynamic, interpersonal, and mindfulness approaches (such as Acceptance and Commitment Therapy).
