Academic Background & Credentials

Barry E. Brenner MD PhD is a dual-trained physician–scientist with more than three decades of clinical, academic, and leadership experience in Internal Medicine, Emergency Medicine, and Microbiology.

 

He earned both his MD and his PhD (Microbiology), graduating in the top tier of his class and being inducted into Alpha Omega Alpha, the national medical honor society. His graduate scientific training included mentorship under Dean S. Gaylen Bradley, PhD — who himself trained under Nobel Laureate Joshua Lederberg, PhD — and Judith S. Bond, PhD, past President of the American Society for Biochemistry and Molecular Biology.

Dr. Brenner trained in Internal Medicine at University Hospitals Case Western University under CCJ Carpenter MD (chair), Leigh Thompson PhD, MD, and David Jackson MD (pioneers of critical care and neurocritical care medicine) and completed residency training in Emergency Medicine at University of Chicago Hospitals with Peter Rosen MD (father of emergency medicine).

 

Dr. Brenner went on to serve as:

  • Residency Program Director

  • Department Chair

  • Professor of Internal Medicine

  • Professor of Emergency Medicine

  • Professor of Microbiology/Biochemistry

  • National lecturer and educator

  • Director of complex-diagnostic services in academic medical centers

 

He has trained and supervised hundreds of residents, written many peer reviewed articles and books on asthma and respiratory disease, and is recognized for his expertise in rapid diagnosis, complex problem-solving, and patient-centered communication. His background uniquely blends internal medicine depth with emergency medicine acuity — a combination that now benefits his patients at Andover Internal Medicine where he plans a unique practice: coupling medical evaluations with a moderate complexity lab and in-office pharmacy: compassionate, clever care with real convenience.

Advanced Diagnostics & In-Office Laboratory

Dr. Brenner operates a CLIA-certified full-capacity laboratory, uncommon in outpatient medicine and extremely rare in DPC practices. This provides rapid, same-visit diagnostic capability usually only found in hospitals.

 

Same-Day Laboratory Testing Includes:

  • Hematology: CBC with differential, reticulocyte count, B12, folate, and ferritin

  • Chemistry: Full metabolic panel, lipids, electrolytes, kidney & liver function

  • Endocrine: TSH, HbA1c, vitamin D, vitamin B12, folate, quantitative HCG

  • Autoimmune: ANA, rheumatoid factor, CRP

  • Microscopy: Gram stain, KOH, Tzanck prep, crystal analysis, polarized microscopy

  • Infectious Disease: Rapid strep, influenza, RSV, COVID antigen, mononucleosis, salmonella, campylobacter, C. diff, procalcitonin

  • Molecular NAAT: Same-day gonorrhea & chlamydia testing, syphilis, and HIV screening, and herpes evaluation

  • Urinalysis & UTI Diagnostics: POC HCG

  • Micro: Blood agar for hemolytic strep

  • Men’s Health: Testosterone, PSA

  • Dyspnea: Spirometry, FENO, ABG, EKG

 

This level of diagnostic capability allows most patients to receive evaluation, testing, interpretation, and treatment in the same visit, without calling back for results or waiting days for answers.

In-Office Pharmacy

Most medications can be dispensed at wholesale prices immediately — so patients leave with the medication they need, not a prescription.

Professional Approach

Dr. Brenner’s practice operates on a simple philosophy: deliver Compassionate • Clever • Care — unhurried, personal, direct, and designed entirely around the patient. His background allows him to solve both everyday health needs and complex medical problems efficiently, accurately, and with genuine personal attention.
