How to Work in Health Care: Your Complete Guide to Building a Rewarding Career
31 Aug, 2023
If you're a healthcare professional with a passion for science, communication, and building meaningful relationships, learning how to become a medical science liaison might be the career pivot that changes everything. I've worked with thousands of healthcare professionals through healthcareers.app, and medical science liaison (MSL) roles consistently rank among the most sought-after non-clinical positions in the industry. These professionals serve as the critical bridge between pharmaceutical companies and the medical community, and the demand for talented MSLs has never been higher.
In this comprehensive guide, I'll walk you through every step of the journey — from understanding what an MSL actually does day-to-day, to the education and experience you'll need, to strategies for landing your first role. Whether you're a pharmacist, a physician, a nurse practitioner, or even a sports medicine doctor looking to transition out of clinical practice, this guide is designed to give you a clear, actionable roadmap.
A medical science liaison is a field-based, non-promotional scientific expert who works within the pharmaceutical, biotechnology, or medical device industry. Unlike sales representatives, MSLs don't carry sales quotas. Instead, they engage with key opinion leaders (KOLs), healthcare providers, and academic researchers to share clinical data, gather medical insights, and support the scientific exchange around a company's therapeutic area.
Think of an MSL as a scientific ambassador. They attend medical conferences, present data to hospital formulary committees, support clinical trial recruitment, and serve as the go-to scientific resource for both internal teams and external stakeholders. According to the Medical Science Liaison Society, the MSL role has grown by over 59% in the past decade, reflecting the industry's increasing emphasis on science-driven engagement with healthcare professionals.
Let me break down the process into manageable steps. I want to be transparent — becoming an MSL isn't a weekend decision. It requires serious academic credentials and typically some form of clinical or scientific experience. But with the right preparation, it's absolutely achievable.
The MSL role is one of the few positions in the pharmaceutical industry that almost universally requires an advanced degree. The most commonly accepted degrees include:
According to the Bureau of Labor Statistics at bls.gov, medical scientists — a category that overlaps significantly with MSL qualifications — typically need a doctoral degree, and employment in this field is projected to grow 10% from 2022 to 2032, faster than the average for all occupations. This growth directly fuels MSL demand.
If you're a sports medicine doctor with an MD or DO, you already meet the educational threshold and bring valuable clinical credibility that pharmaceutical companies prize. The same goes for other specialist physicians, pharmacists, and doctoral-level scientists.
MSL roles are almost always tied to a specific therapeutic area — oncology, immunology, rare diseases, cardiology, neurology, or others. Companies want candidates who can speak fluently about the science in their product portfolio from day one.
Here's how you can build that expertise:
For example, if you're interested in cardiovascular-focused MSL roles, having experience working alongside cardiovascular technologists in a cardiac catheterization lab or echocardiography department gives you hands-on familiarity with the diagnostics and treatment pathways that make your candidacy far more compelling. Understanding how cardiovascular technologists contribute to patient diagnosis and care gives you real-world context that hiring managers find invaluable.
This is where many highly qualified candidates stumble. Having a PhD or MD is necessary but not sufficient. The MSL role is fundamentally about communication — translating complex scientific data into digestible, compelling narratives for busy physicians and researchers.
I recommend:
One of the biggest barriers to entry for aspiring MSLs is the classic catch-22: companies want MSL experience, but you can't get MSL experience without a job. Here are some workarounds we frequently recommend at healthcareers.app:
I cannot overstate how important networking is in the MSL world. Based on data from the Medical Science Liaison Society, over 70% of MSL positions are filled through networking and referrals rather than cold applications. Here's what I suggest:
Your MSL resume should look different from a traditional clinical CV. Focus on:
MSL interviews typically include a scientific presentation component where you'll present clinical data to a panel. Practice delivering a 15-20 minute presentation on a pivotal clinical trial, followed by Q&A. Companies evaluate your scientific depth, communication clarity, ability to handle tough questions, and your overall executive presence.
One of the reasons the MSL career path is so attractive is the compensation. According to the Bureau of Labor Statistics, medical scientists earn a median annual wage of approximately $100,890 as of their most recent data. However, MSL-specific compensation typically exceeds this figure substantially.
Based on industry salary surveys from the Medical Science Liaison Society and other sources:
In addition to base salary, most MSLs receive annual bonuses (typically 15-25% of base), company car or car allowance, equity or stock options, comprehensive benefits, and a home-office stipend since the role is field-based. Total compensation for an experienced MSL can easily exceed $250,000 annually.
Over the years, I've seen successful MSL transitions from a wide variety of healthcare backgrounds. Here are some of the most common:
Interestingly, professionals who have collaborated with cardiovascular technologists, respiratory therapists, and other allied health professionals often bring a uniquely collaborative mindset that translates well into the MSL role. Understanding the full care team — not just the physician's perspective — makes you a more well-rounded scientific communicator.
This is the number one challenge I hear about. My advice: focus on transferable skills. If you've given scientific presentations, managed complex research projects, or built professional relationships with KOLs during your academic or clinical career, you already have MSL-relevant experience. Frame it that way on your resume and in interviews.
Most MSL positions require 50-75% travel. This is a significant lifestyle consideration. I always encourage candidates to honestly assess their willingness and ability to travel before pursuing this career path. The role often covers a multi-state territory, and you'll spend considerable time in airports, hotels, and hospitals.
Many clinicians worry about leaving patient care behind. While the MSL role doesn't involve direct patient care, you're still making a significant impact on patient outcomes by ensuring healthcare providers have access to the latest scientific data. Many former clinicians tell me this broader impact is deeply fulfilling.
The timeline varies depending on your starting point. If you already hold an advanced degree (PharmD, PhD, or MD), you could potentially land an MSL role within 6-18 months of focused preparation and networking. If you're starting from an undergraduate degree, plan for 6-10 years including graduate education and relevant experience building. MSL fellowships, which typically last 1-2 years, can accelerate the process for recent graduates.
While it's not impossible, it's increasingly difficult. Most MSL job postings explicitly require a doctoral-level degree. However, some companies, particularly in the medical device space, may consider candidates with a master's degree combined with extensive therapeutic area expertise and industry experience. If you have a master's degree, I'd recommend either pursuing a doctoral degree or exploring adjacent roles like clinical specialist or field medical advisor that may have more flexible requirements.
This is one of the most common questions I receive. The fundamental difference is that MSLs are non-promotional. They do not carry sales quotas, cannot initiate discussions about off-label uses for commercial purposes, and report into the medical affairs division rather than the commercial division. MSLs focus on scientific exchange, while sales representatives focus on promoting approved products. MSLs also require advanced degrees, whereas pharmaceutical sales roles typically require a bachelor's degree.
Absolutely. A sports medicine doctor brings valuable clinical expertise in musculoskeletal health, pain management, biologics, and rehabilitation — therapeutic areas with significant pharmaceutical and biotech activity. Companies developing treatments for osteoarthritis, sports injuries, regenerative medicine, and pain management specifically seek physicians with this background. The transition from clinical practice to an MSL role also often comes with improved work-life balance and competitive compensation.
Board certification is not required for MSL positions, but it can strengthen your candidacy. The Medical Science Liaison Society offers the MSL-BC (Board Certified MSL) credential for practicing MSLs. For physicians, maintaining your medical board certification demonstrates ongoing clinical expertise. For pharmacists, board certification in a specialty area (such as BCOP for oncology) can set you apart from other candidates.
Learning how to become a medical science liaison is just the beginning — taking action is what separates dreamers from professionals who actually land these coveted roles. Start by honestly assessing your qualifications against the requirements I've outlined. Identify your gaps, whether they're in therapeutic area expertise, presentation skills, or networking. Then build a 6-12 month plan to address those gaps systematically.
