Brownell Mack III, PsyD, LP

Clinic-Based Therapy Services

Having worked in the mental health field for over 20 years, I have extensive experience providing behavioral health assessment and therapy services to children and adults. My clinical competencies include diagnosis and treatment of depression, anxiety, trauma, developmental and intellectual disabilities, substance use disorders, and adjustment difficulties. I provide services in multiple modalities (e.g., individual, family, and couples therapy).

Throughout my career, I have been particularly interested in delivering person-centered care, tailoring my services to clients’ preferences, values, and unique needs. My practice of psychology is guided by principles of resilience and wellness. I constantly aim to utilize each individual’s strengths, adaptive capacities, and sources of joy and purpose to facilitate change.

I view the practice of psychology as a privilege, an opportunity each day to unleash the unique talents and potential that exists within every person. I welcome the chance to work with anyone interested in finding a way through life’s challenges but ultimately in learning how they can thrive amid adversity.

Telehealth Services

To expand and improve our care options for clients, ACP offers Telehealth (phone or video) appointments. Telehealth uses phone or video conferencing to connect you with highly qualified and experienced providers in real-time from the comfort and convenience of your own home or office. Before your telehealth appointment, you will receive details for how you will connect with your provider. If you will be connecting via phone, the provider will plan to call you at your scheduled appointment time. Please be ready to take the call and also check that your phone allows calls from blocked numbers (accessible within your phone settings). If you will be connecting via video conference, your provider will email you an invite to join the appointment. Please call our office to learn more about ACP’s telehealth services and to schedule an appointment.
