For the first time in a decade I feel like I have a doctor who actually knows me. Dr. Marco caught a thyroid issue three other physicians missed.

Our Philosophy
Medicine Should Work Before You Get Sick
Allicere was founded on a simple but radical idea: aging is not something to accept passively — it's something to understand, measure, and optimize. We practice proactive medicine, not reactive treatment.
- Scientific Integrity — We only practice what evidence supports, never chasing trends without clinical validity
- Precision Personalization — Your care is built around your biomarkers, genetics, and individual biology
- Optimization over Normalization — "Normal" is not the goal. Your highest function is the goal
- Healthspan first — Extending life only matters if those years are lived with strength, cognition, and independence

Real people, measurably better.
A few words from patients who've spent a year — or several — inside our care.

My biological age dropped almost six years. But the bigger thing is how I feel — sharper, calmer, way more like myself. Allicere changed how I think about getting older.

She's the first physician who treated my labs as a starting point and not a verdict. Genuinely warm, deeply rigorous. I send everyone I love here.

Questions
Everything You Want to Know
Straightforward answers about our services, approach, and how to get started with Dr. Marco.
Some diagnostic labs may be partially covered by your plan. Our longevity programs are primarily self-pay, giving Dr. Marco the freedom to practice medicine without insurance limitations. We offer flexible payment plans and can provide documentation for FSA/HSA reimbursement.
Our programs are designed for adults who want to be proactive about their health — typically 35 and older. You don't need a diagnosis to start. Both healthy individuals wanting to optimize, and those noticing early signs of decline, are ideal candidates.
Traditional concierge medicine still operates reactively — it just offers more access to that reactive care. Allicere is built around longevity science: we use advanced diagnostics, biomarker tracking, and individualized protocols to identify and address risk before disease develops.
Yes. While initial assessments and certain therapies require an in-person visit at our DFW clinic, follow-up consultations, protocol reviews, and ongoing check-ins with Dr. Marco are available via secure telehealth for patients in Texas.
Pricing varies by program and is discussed during your free discovery call. We offer single assessments as well as ongoing membership programs. Flexible payment plans are available, and we can provide documentation for FSA/HSA reimbursement where applicable.
