Green Park & Golf Ventures

Green Park & Golf Ventures (GPG Ventures) is a Dallas-based healthcare-focused venture capital firm founded in 2011, built on more than 60 years of combined operational and financial experience in the healthcare sector. The firm is led by co-founders Dr. Clay Heighten and Carl Soderstrom, who previously built MedicalEdge Healthcare Group (founded 1993, managing 550-plus providers across five major markets) and PhyServe Physician Services (founded 1998), both of which were sold to Texas Health Resources — a $3.8 billion healthcare system — in 2011. GPG Ventures operates three offices in Dallas, Houston, and Austin and invests nationally. The team includes Daniel S. Parsley as Managing Partner in Houston, Claire England as Investment Partner in Austin, and JR Garcia as Partner. The firm deploys $500K to $2 million per investment, targeting biotech, digital health, medtech, pharma, and consumer health companies at Seed and Series A. The portfolio spans 85 to 115 investments with five IPOs and twelve acquisitions. Notable portfolio companies include Lantern Pharma (Nasdaq: LTRN, AI-driven oncology drug development), Savara Pharma (specialty pulmonary drugs), Retrotope (neurodegenerative diseases), Iterion Therapeutics (targeted cancer therapeutics), and Gregor Diagnostics, which received a Series A-II investment in November 2025. GPG Ventures looks for companies with disruptive ideas, passionate seasoned management teams, large addressable markets with high barriers to entry, and aligned incentives across all stakeholders. The firm's founders bring direct experience scaling physician management businesses, providing portfolio companies with practical operational credibility rather than purely financial guidance.
