Medical Director & Founding Physician

SPHERE FERTILITY — Miami Flagship

Location:  Miami, FL 

Reports to:  CEO

Role type:  Full-time, on-site 

Start date:  Flagship opening, 2026

Compensation:  Competitive base + productivity + equity participation

SPHERE FERTILITY is a next-generation reproductive medicine practice built on the premise that patients deserve a fundamentally better fertility experience: unhurried care, exceptional clinical outcomes, and physicians who know them by name. Our Miami flagship will be the first expression of that vision — a concierge-grade clinic with an in-house embryology lab, integrated genetics, and a design-forward environment that treats patients as whole people rather than cycles on a schedule.

We are hiring a Medical Director and Founding Physician to build and lead the clinical practice at our Miami flagship. This is a rare opportunity for a Reproductive Endocrinologist who wants the creative latitude of a founder, the backing of a mature capital partner, and the tools to practice medicine the way they always believed it should be practiced.

The Medical Director will own clinical strategy, protocols, lab oversight, and patient experience from day one. They will be the clinical face of the brand in South Florida and a central voice in how SPHERE scales.

• Deliver high-touch reproductive care across IVF, IUI, egg and embryo freezing, donor cycles, gestational carrier cases, and fertility preservation.
• Personally perform oocyte retrievals, embryo transfers, and complex monitoring; own a manageable caseload consistent with a concierge model.
• Manage complex and sub-specialized cases, including DOR, PCOS, endometriosis, recurrent pregnancy loss, male factor, and reproductive immunology referrals.

• Define and maintain stimulation protocols, lab SOPs, and quality metrics in partnership with the embryology and nursing leads.
• Serve as the final clinical authority for the Miami flagship; recruit, mentor, and evaluate future REIs, fellows, NPs, and nursing staff as the practice grows.
• Own outcomes reporting (SART, CDC) and drive continuous improvement against age-stratified benchmarks.

• Partner with the Lab Director on IVF lab design, equipment selection, and commissioning of the in-house embryology lab.
• Ensure compliance with CAP, CLIA, FDA, and state requirements; lead audit readiness and accreditation workstreams.
• Shape EMR configuration, clinical workflow design, and patient journey mapping alongside the operations team.

• Serve as the clinical face of the Miami flagship — patient events, media appearances, podcast guesting, and physician referral-building.
• Contribute to content, education, and peer-reviewed publications that establish Sphere’s clinical credibility.
• Collaborate with the founding team on expansion strategy, including future flagships and clinical affiliations.

• MD or DO from an accredited medical school.
• Completed residency in Obstetrics & Gynecology.
• Completed fellowship in Reproductive Endocrinology and Infertility (REI).
• Board certified in OB/GYN (ABOG); board certified or board-eligible in REI.

• Active, unrestricted Florida medical license (or ability to obtain prior to start).
• Active DEA registration in good standing.
• Clean National Practitioner Data Bank (NPDB) record — no material disciplinary actions, license restrictions, or unresolved malpractice claims.
• Eligible for hospital privileges at affiliated Miami-area facilities.
• Current malpractice coverage (or insurability) at or above Florida and Sphere minimums.

• Minimum 7+ years of post-fellowship REI practice, with a track record as a primary attending.
• Demonstrated independent volume across IVF, IUI, egg freezing, embryo transfer, and ovarian stimulation.
• Proficiency in transvaginal ultrasound, oocyte retrieval, and fresh and frozen embryo transfer.
• Experience with third-party reproduction: donor eggs, donor sperm, and gestational carriers.
• Fluency with PGT-A/PGT-M workflows and close coordination with embryology.
• SART-reportable outcomes at or above national age-stratified benchmarks; strong management of OHSS and multiple-pregnancy risk.

• Prior role as Medical Director, Lab Liaison, Practice Lead, or equivalent — or clear readiness to step into that scope.
• Experience building or meaningfully upgrading protocols, SOPs, or quality programs.
• Track record of recruiting, developing, and retaining clinical talent.
• Comfort with P&L awareness, productivity-based compensation structures, and operating within a venture- or family-office-backed practice.

• Comfort and polish in front of patients, press, and referral partners — media-trained preferred.
• Publications, conference presentations, or teaching appointments that establish thought leadership.
• Active in ASRM, SREI, or equivalent professional societies.

• Deeply patient-centered; longer consults and direct patient access energize you rather than drain you.
• Collaborative with embryology, genetics, nursing, mental health, and operations peers.
• Evidence-based and protocol-driven, with the intellectual honesty to update practice as the science evolves.
• Cultural competency for a diverse Miami patient base; Spanish fluency is a strong plus.

• Sub-expertise in fertility preservation, oncofertility, LGBTQ+ family building, or reproductive immunology.
• Active IRB-approved clinical research or published original research in the last 3 years.
• Existing Miami- or Florida-based referral network.
• Prior experience opening a de novo clinic or lab.
