Margery K. Calhoun, PhD in Baltimore: Clinical Psychology with a Neuroscience Foundation

Margery K. Calhoun, PhD, is a clinical psychologist with a doctorate in neuroscience who practices individual and group therapy in Baltimore, bringing neurobiological evidence into talk-based mental health treatment. Her practice focuses on anxiety disorders, depression, trauma, and addiction, with particular expertise in how brain function underpins behavioral and emotional patterns. She works with both insured and self-pay clients and accepts most major health plans.

What the practice actually is

Calhoun operates as an independent clinical psychologist licensed in Maryland, holding a PhD rather than an MD, which means she diagnoses and treats mental health conditions through psychotherapy but does not prescribe medication. Her doctorate in neuroscience distinguishes her from many Baltimore psychologists; she uses functional understanding of brain systems (limbic, prefrontal, autonomic) to explain why certain therapeutic techniques work and to tailor treatment to the individual. The practice accepts existing patients and screens new referrals, which is standard for established PhD psychologists in Baltimore who maintain a caseload tied to one location rather than a large group practice.

Services and what to expect in cost

Calhoun offers weekly individual psychotherapy (50-minute sessions), group therapy for specific conditions, and consultation for other providers. Standard Baltimore-area rates for PhD psychologists in private practice range from $150 to $250 per session; specific pricing for Calhoun's practice requires a direct call, as rates vary by insurance coverage and self-pay arrangements. Many insurance plans cover a portion of out-of-network mental health care; your out-of-pocket cost depends on your deductible, coinsurance percentage, and whether your plan waives the deductible for mental health services. Initial consultation typically lasts 60 to 90 minutes and determines whether treatment fit is right for both parties.

How Calhoun compares to other Baltimore psychologists

Baltimore has several thousand licensed mental health providers. For those specifically seeking a PhD psychologist with a clinical neuroscience angle, Calhoun represents a less common profile; many Baltimore psychologists hold an MA or PsyD and may not emphasize neurobiology in their approach. Johns Hopkins psychology faculty (some of whom treat patients) and a handful of private practitioners with neuroscience backgrounds offer similar models, but they often have extended wait lists (sometimes 6 to 12 months) or work only with specific insurance networks. Calhoun's approach differs from standard cognitive-behavioral psychotherapy practices in the city, which tend not to foreground brain function; it also differs from psychodynamic practitioners who prioritize unconscious patterns over neurobiological mechanisms. For those with insurance covering out-of-network mental health and flexibility on scheduling, Calhoun's model suits patients who benefit from understanding the "why" behind their symptoms in neurological terms.

Who is a fit and who is not

Calhoun's practice is well suited to adults with anxiety, depression, complex trauma, or substance-use patterns who want explanation alongside treatment and are comfortable with a slower-paced, insight-oriented approach. Group therapy cohorts require a baseline level of stability and willingness to engage with others. She does not appear to focus on couples therapy, child and adolescent care, or crisis intervention; Baltimore residents in acute suicidal crisis should contact the Baltimore Crisis Response Team (410-433-5500) or go to an emergency department. Self-pay patients should expect to budget $150 to $250 per week and plan for ongoing sessions (typically 4 to 6 weeks minimum before meaningful progress is assessed). Those needing immediate availability or crisis slots will find more availability through community mental health centers such as Kennedy Krieger or National Institutes of Health affiliated clinics.

First visit and scheduling

New patients call to discuss their presenting concern and whether there is a fit. Calhoun evaluates diagnostic clarity, safety, motivation, and logistical compatibility (scheduling, payment). If she is accepting new patients, an intake appointment follows, which runs 60 to 90 minutes and covers psychiatric history, current symptoms, substance use, medications, family history, and goals. Bring your insurance card and photo ID. The appointment also determines whether weekly therapy is recommended or whether group work is a better starting point.

Hours and logistics

Contact Calhoun directly at her office to confirm current hours and location within Baltimore. Parking availability depends on the specific office location; call ahead if parking access is a concern for you.

Calhoun's integration of neuroscience into clinical practice provides Baltimore patients with an alternative to purely behavioral or talk-based therapy, especially valuable for those who respond to understanding mechanism as part of healing.
