Executive performance & longevity doctor
Diagnostics-led systems for founders, executives, and pros who want steady energy, sleep, and sharp decision-making.
Discretion-first, referral-led practice.
Afternoon crashes taper; reaction time variance tightens.
Deep/REM stabilize across travel and load.
Inflammation and cortisol patterns normalize.
Decision quality holds under pressure.
What Changes
All this means is: you’ll know what to change, in what order, and you’ll see it in the numbers.
Proof
Founder, 46 | 10 weeks
Baseline: Deep sleep 47 min; HRV 38 ms; 2 p.m. decision fatigue.
Intervention: Light timing, meal timing, travel protocol, strength micro-cycles.
Delta: Deep sleep 1h24; HRV 56 ms; decision speed +27% on cognitive test; crashes resolved.
Pro tennis, 31 | 12 weeks
Baseline: Morning cortisol spike; quad tendon pain; 3rd-set fade.
Intervention: Circadian reset, tendon-safe strength, anti-inflammatory block, court load map.
Delta: Match-end movement quality up; pain 0–1/10; winrate in deciding sets +18%.
How it Works
The process is very simple:
-
Bloodwork, sleep architecture, recovery, cognition, movement screens. We map where coherence is lost and what matters most.
-
One variable at a time: light and rhythm, training, sleep, nutrition, travel, recovery. Team integration if you have MD/coach/trainer in place.
-
Quarterly tune-ups; annual rebuilds when goals or load change. Confidential, minimal time cost, decision-grade reporting.
All this means is: measure first, act second, track honestly.
Dr. Donald Shrump
Scientist turned decathlete turned doctor. Early career in marine biology taught me to respect data and pattern. Sport taught me that more effort isn’t progress. Medical training taught me to sequence change and tell the truth about timelines. Today I integrate diagnostics with real-world constraints for people whose work carries weight.
Worked inside teams with Olympians, touring pros, executives, and surgical leaders. Discretion is standard.
Who I work with
Founders & executives
facing plateaus, travel load, and board-level stakes.
Professional athletes
competing for longevity and consistency.
Surgeons
protecting hands, posture, and stamina.
Creatives
looking for optimal performance during intense schedule and longevity in their careers
If you already have an MD, trainer, and nutritionist, I align the work so efforts don’t collide.
