Home Base Welcomes New Chief Medical Director, Announces Clinical Leadership Updates

Thomas Spencer, MD

Veterans and their families at Home Base will have a new friend keeping tabs on their health and well-being thanks to the appointment of Tom Spencer, M.D., as Home Base’s new Chief Medical Director. He succeeds Naomi Simon, MD, who held the position of Chief Medical Officer.

“We are honored and delighted to have Dr. Spencer assume the role of Chief Medical Director at Home Base,” Home Base Executive Director, retired Brigadier General Jack Hammond said. “He brings a passion for the Home Base mission and sensitivity to the needs of those who receive care in our program; he will be a model of integrity and compassion for those who rely on us for their health care services.”

Dr. Spencer’s varied clinical experience makes him a well-known presence throughout the Massachusetts General Hospital (MGH) – recently serving as Assistant Chief of the Pediatric Psychopharmacology Research Program. Before arriving at the MGH, Dr. Spencer served as the Head of the Clinical Team, Child and Adolescent Division, of the Massachusetts Department of Mental Health. His research and clinical interests have focused on the effectiveness and safety of standard and novel pharmacologic treatments of Attention-Deficit/ Hyperactivity Disorder (ADHD) throughout the life-cycle.

In his role as Chief Medical Director at Home Base, Dr. Spencer plays a critical role spearheading Home Base’s clinical initiatives and partnering with internal teams to support the expansion of Home Base’s Intensive Clinical Program (ICP) and furthering innovation within Family Services and the Outpatient Clinic (OPC).  “Home Base has been a clinically-driven organization from the start, and we look forward to leveraging Dr. Spencer’s breadth of clinical experience in both adult and pediatric medicine to sustain and build on the high-quality standard of care that has earned us our strong position in supporting the entire military family,” adds Michael Allard, Chief Operating Officer for Home Base. “His clinical background and operations expertise will provide the vision and leadership not only for our clinical services but also for our teaching and research initiatives.  We are thrilled he has joined our organization.”

Dr. Spencer, likewise, expresses enthusiasm about joining Home Base.

“I am humbled, excited and awed to join such a highly esteemed organization. An organization that is devoted to improving mental health care for our Veterans and their families,” Spencer concludes. ” I’m eagerly looking forward to working with our team of skilled and dedicated professionals. Moving forward we will be working together to advance Home Base’s impact in the field of mental health and brain injury care.” 


Moving forward, Home Base will implement a new clinical leadership structure within the ICP and OPC that will allow the program to enhance patient-focused programming and increase access allowing us to achieve broader reach among Veterans and their families. “Even at the Massachusetts General Hospital, which is full of some of the world’s best physician-scientists, Home Base clinicians continue to stand out in their respective fields, continually seeking innovative ways to define new standards of care,” adds Hammond.

With that in mind, Home Base has named Simon Lejeune, MD Medical Director for the ICP; he will co-direct the ICP with Peg Harvey, PsyD. Dr. Lejeune began his tenure at Home Base in September 2017.  He has a background in general psychiatry and has worked in inpatient, partial hospital, and outpatient settings. His clinical interests and expertise include major mental illness, suicidology, and addictions. He has taught psychiatric residents and Harvard CME courses for many years as well as consulting to other clinics and educational institutions.

Additionally, Kalo Tanev, MD will assume the role of Medical Director for the OPC and he will co-direct the OPC with Liz Goetter, Ph.D. Dr. Tanev has been amongst a group of clinicians at Home Base who share a passion for the development of neuropsychiatry. A specific area of interest for Kalo within neuropsychiatry is sleep disturbances in hospitalized patients with Alzheimer’s or vascular dementia. He is also interested in identifying successful treatment strategies for traumatic brain injury.

“The future of care for our veterans and their families starts and ends with collaboration among experts to provide the most effective and efficient outcomes,” adds Allard. “And we are immensely proud of our clinical team and the impact they have had on veterans and families here in Boston, New England, and across the Nation.”

As Home Base welcomes Drs. Spencer, Lejeune and Tanev to their new leadership positions, we offer our heartfelt appreciation for your unwavering support of the Home Base mission as we undertake this important work to heal the invisible wounds, now and in the future.
