Clinic A - Three Vlans:
Vlan 1 - 192.168.140.1 (Internal Data)
Vlan 2 - 192.168.32.2 (Inter-office traffic)
Vlan 3 - 172.16.140.1 (Voice)

Clinic B - Firewall (192.168.100.104)
Router 192.168.100.1

Clinic C - 192.168.180.1

Clinic A can ping everything at Clinic B (and vice versa) from all interfaces

Clinic B can ping everything at Clinic C (and vice verse) from all interfaces

Clinic A Vlan 2 can ping Clinic C and vice versa

Clinic A Vlan 3 can ping Clinic C and vice verse

Clinic A Vlan 1 CANNOT ping Clinic C nor can Clinic C ping Vlan 1 at Clinic C

Debug ICMP at Clinic A shows that ICMP traffic hits it and a reply is sent back. No reply is ever received at Clinic C.

Here's what's getting me - Clinic A is using the same routes for each VLAN - if the other two can hit Clinic C, why can't VLAN1? What could possibly be stopping 192.168.140.0 traffic from replying properly back to Clinic C?

are you trunking the VLANS? copy and paste the configs and I'll tell you what the problem is
 
What subnet masks are you using on all those devices? What subnet masks are on the router?
