About Us


As a self-made man, Marlow Gish understood the challenges involved in creating, sustaining, and increasing corporate market share and in 2012 founded Professional Analytical Services (“PAS” and “we”) to streamline a uniform process of analytics for companies to develop stronger market share and penetration in both the public and private arena.

Gish has structured PAS as a holding company, parent to five independent subsidiary trusts:

  • Gish Analytics Trust to redesign corporate structural agility, sustainability, extensibility, predictability, and accountability within a comprehensive analytical proprietary toolbox.
  • Gish Consulting Trust to compel economic returns to its clients by accelerating performance improvements in EBITDA, cash flow, growth, market penetration through operations excellence, strategic procurement, and logistics.
  • Gish Marketing Trust to promote client acquisition, proprietary branding, advertising, digital marketing optimization and positioning.
  • Gish Private Equity Trust to employ deal generation, due diligence, value creation, exit planning, firm and sector strategies, and institutional strategies.
  • Gish Commercial Acquisition Trust to acquire nationwide ESG friendly real estate opportunities for REIT merger integration and structuring.
All subsidiary trusts work both independently and comprehensively to create a cohesive toolbox of performance enhancement, financial restructuring, and corporate innovation in both market penetration and positioning.


We believe that every client is unique and deserves a comprehensive process that is tailored to meet client objectives. Rather than implementing a uniform process for all companies, we create a customized and creative process to adhere to clients’ interests while developing a best-in-class outcome. While we leverage our deep industry experience and knowledge for all projects, not all situational aspects are always consistent for similar companies in the same industry. Therefore, we focus on remaining thoughtful, thorough, and open-minded in understanding our clients’ businesses and developing our marketing approach and positioning strategy.


We innovate our financial analytical models and apply this proprietary platform to achieve outstanding outcomes. By establishing design, process, product, and service differentiators, along with our unique market approach, we help companies develop market penetration more rapidly and their clients appreciate the rationale for our action. We implement this proprietary platform using an open-ended approach to foster transparency, distinguishing us from our competitors. We develop strong client relationships by superimposing corporate honesty and integrity in all our innovative dealings, elevating our reputation as a company known to always do what we say we can do and refusing to take on ventures that do not benefit our clients fully.


We achieve best-in-class outcomes by leveraging our industry expertise and tailoring each process to achieve the optimal outcome. We are able to gain direct access to and attention from the key decision makers through our industry relationships and reputation. Furthermore, we have a demonstrated history of running tailored processes to achieve best-in-class results. Not every company is the same, and therefore not every process should be the same. Our extensive completion experience and repeat business results from consistent success positioning businesses for best-in-class results. We have a demonstrated history of finding solutions for the most complex transactions.
