# How to Build Credibility in Medical Sales When You're New to the Specialty A former Allergan Health System Manager shares the practical habits that earned trust, access, and President's Club results in a new medical sales specialty. By Jebb C. Ruff, MBA ยท 2026-10-02 There was a point in my career when I knew it was time to start over. I had built a solid career in Allergan Dermatology. I understood the customers, the specialty, the language, and the relationships. I was comfortable. But comfortable is not where growth lives. When several dermatology products were approaching patient expiration, I could see the long-term opportunity shifting. So I moved from Allergan Dermatology into Allergan Neurology: a new specialty, new customers, new coworkers, and new systems. Neurology was growing fast, with major treatment areas in Alzheimer's disease, Parkinson's disease, multiple sclerosis, and chronic migraine. I was covering half of Texas, working with major IDNs, academic medical centers, and Veterans Hospitals while supporting nine indications of a neurotoxin. There were only 34 Health System Managers in the United States. The group was small, the standards were high, and there was no room to hide. The question was uncomfortable but simple: how do you become a top performer in a room where everyone seems smarter and more talented than you? That question taught me more about medical sales, leadership, and career growth than almost anything else in my 22 years in the industry. Eventually, it led to President's Club. ## Compassion Comes Before the Sale When you enter a new specialty, the temptation is to lead with the product. I did the opposite. I led with the people. Every person inside a healthcare organization has a different job, set of pressures, and definition of success. Treat them all the same and you will lose every one of them. A physician wants clinical evidence, patient-selection criteria, outcomes, and appropriate use. A nurse is focused on workflow, patient education, scheduling, and what happens after the physician makes the call. Front-desk staff care about how a decision affects their day. A purchaser thinks about ordering, inventory, contracts, and utilization. A CFO is weighing financial performance, risk, and return. Same building. Completely different worlds. Before I ever tried to sell anything in Neurology, I learned what conditions customers treated every day, which patients they saw most often, what their workflow looked like from morning to close, who influenced the clinical decision, who influenced the purchase, who controlled the budget, and how a patient moved through the health system from referral to treatment. You do not need to know everything on day one. You do need to know what is happening in your territory. ## Credibility Has to Be Earned Before It Can Be Used Nobody cared what I had done in the past. Walking into Neurology, my Dermatology track record meant nothing to a physician who had never met me. My trust meter was at zero, and I had to earn credibility again. That meant homework: studying the specialty, the data, the accounts, the geography, and how to run an effective product injection training. I studied how the top performers in the division prepared before they ever set foot in a hospital. Here is what I still tell every client I mentor: confidence should come from preparation, not from being the smartest person in the room. In medical sales, success is not about proving you know more than everyone else. It is about being the representative who listens closely, solves problems, earns trust, and makes a customer's day easier. ### Three questions that build credibility - Why does this matter to this specific customer? - How does this problem affect their day, their patients, and their outcomes? - What does the data say, and what is the realistic next step? Those questions forced me to stop thinking like a product expert and start thinking like a business partner. Data alone does not build credibility. Data, context, and a story that people remember do. A mentor also taught me the power of three: organize your message around the need, the evidence, and the path forward. A strong sales conversation is not a data dump. It is a journey that helps the customer see where they are, what is happening, why it matters, and what could be different. ## Character Is Built When No One Is Watching You can understand a physician's specialty, memorize every data point, run a flawless demonstration, and build a sharp territory plan. Eventually, none of that decides whether a customer trusts you. Trust is bigger than what you say. It is your tone of voice, body language, consistency, and willingness to say, 'I don't know, let me find out,' instead of bluffing. It is following through when you said you would call someone back. It is how you show up on a bad day and whether you cut corners when nobody is watching. Healthcare professionals are dealing with patients, budgets, reputation, and outcomes. They are asking one important question: can I trust this person? When the answer becomes yes, professional momentum starts to build. Customers open their doors. They return your messages without being chased. They ask what you think. They introduce you to someone else in the building. That is the moment access begins to compound, and it changes the trajectory of a territory. ## Starting Over Is Not Starting From Zero Looking back, I never started from zero. I started with experience. I just had to translate it. The fresh start became one of the most valuable chapters of my sales career. It pushed me out of my comfort zone, forced me to sharpen my skills, and made me a stronger sales professional. I already knew how to sell, build relationships, manage a territory, prepare, and compete. What I did not know was Neurology, so I learned it piece by piece, week by week. That is the distinction every career changer needs to hear. A nurse does not start from zero. A B2B sales representative does not start from zero. A teacher, dental hygienist, pharmacy technician, or retail leader does not start from zero. They may be missing industry-specific experience, but they have capability. The work is learning how to translate that capability into the language medical sales hiring managers understand. That translation is positioning, and positioning is what creates access. ## How Aspiring Medical Sales Reps Build Credibility I have sat on both sides of the hiring table. When I work with someone searching for a career in medical sales or a professional who wants a promotion, I am not giving them a generic template. I look at their specific situation and help them build three things at the same time: access, strategy, and momentum. ### Access Who needs to know you exist? Who can open a door? How do you create conversations in a market where hundreds of talented candidates apply? ### Strategy Which companies should you target? How do you position your background so a hiring manager sees the value immediately? How do you translate your existing skills into business language they trust? ### Momentum What are you doing this week to move forward? Who are you talking to? What are you learning and improving today? Activity without strategy can keep you busy for a year and get you nowhere. Strategy without access can leave you invisible, no matter how good your resume looks. Access without preparation might get you in the room, but it will not help you win the job offer. You need all three working together: Access + Strategy + Momentum = Hired. President's Club did not come from motivation alone. It came from thousands of small, consistent decisions: building the territory, prioritizing accounts, planning travel, studying the specialty, running the demonstration, and following up when it would have been easier not to. One good conversation creates the next one. One solved problem opens the next door. Small actions stop feeling small and start becoming a reputation. ## One Question Before You Go After 22 years in this industry, after hiring, firing, mentoring, and building winning teams across multiple states, here is what I know: most applicants do not fail to break into medical sales because they are not good enough. They fail because they walk into one of the most competitive interview processes in corporate America with hope instead of a plan. If you are serious about breaking into pharmaceutical sales, earning a promotion, or building a six-figure medical sales career, prepare your career story, transferable skills, company research, STAR examples, and smart questions that make hiring managers remember you. What is one thing you did in a new role, city, or industry that helped you earn trust faster?
