By the time your starting material is in our hands, you will know your quality assurance expert and customer service collaborator by name. Over the past three decades that we have built our reputation of quality and excellence, we could have shifted to an impersonal fast-track approach, but that simply doesn’t align with what we know is important — partnership. We believe in standing by your side, being an extension of your team, and providing confidence at every stage of your work so you can be BreakthroughReadyTM.
For over three decades, Puresyn has intentionally taken a collaborator approach which means we:
Stand side-by-side with you.
We collaborate to understand the unique needs of your work, share consultant-level insight and advice, and provide high-quality plasmid DNA services.
Work as an extension of your team.
From the very first phone call, what matters most to you matters most to us.
Value a long-term working relationship.
Whether it’s the first time you reach out to us or you’ve been collaborating with Puresyn for years, we treat you and your work with utmost care and attention.
Show up for you, every time.
When you call, we respond immediately. No waiting around. No leaving messages in a voicemail void. When you need us, you can count on us to be there at every point along the way.
Keep you updated.
We provide regular reports and updates, so you’re always on top of our progress — with full transparency on your plasmid.

Long-term commitment starts at the top. Our leadership team has roughly 100 years of experience in plasmid DNA manufacturing right here at Puresyn. Always accessible and easy to work with, their vision and dedication shape everything we do.
Leslie started at Puresyn as an Office Manager in 1992. Over the years she worked her way to VP and General Manager. She is responsible for Administration, Human Resources, Legal, Finance, Equipment, Facilities and anything else that needs attention.
Dana started her career with Puresyn in 1998 as a Purification Scientist. Over the years, she has worked in both Quality Control and Quality Assurance. Currently, Dana is responsible for Quality and Operations and oversees the INDReady® Program. Dana takes the lead in customer onboarding, the quoting process and scheduling — as well as communication before, during and after each production. Additionally, Dana hosts and responds to Collaborator Audits and aids in HR and Business Development.
Trained as a Fermentation Scientist, Mike began his career with Puresyn in 1998 performing viral purification and characterization. After working in plasmid purification for 11 years, he became Manager of the Fermentation Department. In his current role as Director of Business & Process Development, Mike’s main function is to align company efforts with guidance and regulatory compliance and help our collaborators do the same. He also assists in Puresyn’s marketing efforts.
Denise joined Puresyn in 2004 as a Purification Scientist before making her way into Production. Ultimately, she became Production Manager and then Production Director. Denise is responsible for all day-to-day production, operations, scheduling and troubleshooting.
Throughout Puresyn’s 30+ years of development work, collaboration has always mattered the most to us. We’re proud that our efforts support the academic, government, biotech and pharmaceutical communities — and make a daily difference to collaborators like you.

“Just a quick note to thank the Puresyn team for the regular and well-documented weekly updates for our plasmid project. Also very much appreciate the flexibility in working with us to get a cell bank sample shipped to our External Contract Testing Lab.”
“I hope that we can work together sometime in the future, as Puresyn has been an excellent partner.”
“I can absolutely confirm that Puresyn plasmid was used in EVERY batch of lentiviral vector that was used to dose EVERY patient in the phase 1 and registration studies.”
“I recommended Puresyn for our company RFI. I have really enjoyed working with Puresyn for our products and let my new organization’s supply Team know how well this has worked for us in the past.”
“Thank you for the services, we appreciate the timelines Puresyn has been able to maintain!”
“I appreciate it when I come across a good organization and enjoy seeing people with passion for what they do!”
“I want to say that it has been a real pleasure working with a local company like Puresyn. I will always appreciate how you saved us when we were in a pinch earlier this year. Personally, I plan to stay in the area, so perhaps we will work together again.”
