The FPrin way

Fprin offers “first principles” oriented, knowledge-driven design and engineering services to our clients.  We deliver cost-effective innovation by leveraging computational methods and targeted testing to explore the design space and identify robust operating regimes. These tools enable cost-function driven optimization and Monte Carlo simulation. 

We have demonstrated that this process results in will work designs that culminate in demonstration prototypes, supported by robust analysis, that are scalable, rather than can work, one-off, designs that may not be reproducible.

This helps the decisions makers:

Data Design Decisions Icon

Make informed design decisions based on data – not guesswork and hope. We simulate to refine the design and test to confirm the prediction and demonstrate the required function.

Prototype Select Down Icon

Finish the design process in an
efficient manner. You won’t be left wondering if there is a better design within the same constraints.

EVT and DVT validation completion icon

Brings design assurance which enables passing phase gates like EVT & DVT and confidently  transferring into manufacturing.

Our Process:

We Foster A Culture That Encourages Asking "Why?" and Managing Risk Through Analytically and Empirically derived Data to Drive Decision Making

This “go slow now to go fast later”, First Principles based alternative to a “design by analogy” (DBA) approach enables objective design decisions.  Models, simple test, careful consideration of what the models tell us, and application of the models as design tools all support a more reliable, predictable, and efficient product development process.

This is the approach that we employ at FPrin. We perform analysis, modeling, and test to build a knowledge base for your design. We use this to determine strengths and weaknesses of the design and to map an informed approach to design development. This knowledge tells us where we need to focus our efforts – specifically on “make or break” design elements – and where we can afford to defer closer scrutiny. It allows us to put the right resources on the right problem at the right time.

Our People

FPrin is grounded in the principles of fair treatment of its staff and suppliers. Our passion is helping our clients to deliver safe and effective products to enhance the lives of their customers.  We work together to foster a culture that offers superior value to our Clients by building a financially strong company where we all share the benefits and enjoy a meaningful and fulfilling journey.

Anna Kovchina

Liz Tuzzolino

Director, Business Development

Liz Tuzzolino

Focused primarily on medical device sales, Liz’s role includes development, implementation and streamlining systems for the FPrin team.

She has over 15 years of experience in medical device engineering & manufacturing services with a particular focus on Drug Delivery & Diabetes management systems. Her expertise ranges from large diagnostic instrumentation, complex minimally invasive devices, to active implantable devices, drug deliver and wearables. She is a natural collaborative team builder.

Although she has worked in Boston & the Silicon Valley for over 15 years, her home is Colorado where she spends her free time with family, hiking, biking and practicing yoga.  Prior to Joining FPrin she worked with Radius a Jabil Company, Triple Ring and Cirtec Medical Systems. 

Peter Holst

Founder

Peter Holst

Peter Holst, Founder, has nearly 30 years of experience in R&D and product development in the field of medical devices and equipment.  He has experience with visual field testers, IV and enteral pumps, surgical robots, cholesterol testers and glucose meters.  He is experienced with drug delivery technologies for liquid drug formulations as well as pulmonary and trans-dermal methods.

Peter is a strong proponent of data driven design methods known as “Lean Engineering” or “Knowledge Driven Product Development”.  With these methods the outcome of the design process is a design that is well understood – by analysis, modeling, and simulation – and well characterized – by directed testing, typically at the sub-system level.  Using this process the design can be typically characterized as “will work” rather than “can work” before making major capital commitments.  Peter has experience in design for high volume manufacturing using various component manufacturing methods including plastic injection molding, metal injection molding, casting, powder metal, sheet metal and machined components.  He also has background in the design of low volume capital equipment medical mechanisms and systems.

Peter has a BSME from Northwestern University and an MSME with a concentration in dynamics and controls from Santa Clara University.
